O camu-camu [Myrciaria dubia (Humb., Bonpl. & Kunth) McVaugh], da família Myrtaceae, é encontrado em áreas inundáveis da Região Amazônica e utilizado como conservante em antioxidantes por seu alto teor de ácido ascórbico. O objetivo deste trabalho foi avaliar porta-enxertos desta família, adaptados a terra firme, visando à propagação vegetativa de camu-camu. Selecionaram-se duzentas e quarenta mudas de camu-camu, goiabeira (Psidium guajava L.) e pitangueira (Eugenia uniflora L.), que receberam quatro tipos de enxertia, originando doze tratamentos de sessenta plantas, com cinco repetições. Apenas o porta-enxerto de camu-camu se mostrou compatível. A incompatibilidade entre camu-camu e os porta-enxertos de goiabeira e pitangueira foi demonstrada por análises anatômicas. Camu-camu [Myrciaria dubia (Humb., Bonpl. & Kunth) McVaugh], of the Myrtaceaefamily, can be found at flooded areas in the Amazon region and it is used like a conservant in antioxidants due to its high ascorbic acid content. In order to obtain rootstocks of this family adapted to dry land for vegetative propagation of camu-camu, two hundred and forty plants of camu-camu, guava (Psidium guajava L.) and Surinam cherry (Eugenia uniflora L.) were selected. They received four different kinds of grafting, originating twelve treatments of sixty plants and five repetitions. Only the camu-camu rootstocks showed compatibility. Incompatibility between camu-camu and the rootstocks of guava and Surinam cherry was demonstrated by anatomical analysis.

The height of mango trees is, in general, of the order of 10 to 12 m, with a crown diameter of 7 to 10 m, a size that is not compatible with management practices such as phytosanitary spraies and harvest. The reduction of the crown of the mango tree to half its size would permit a higher plant density per hectar, a greater facility of management practices, like harvest and deseased branch pruning. As a consequence a higher yield is also expected. This note is presented with the aim of discussing this issue.

O objetivo deste trabalho foi verificar a interferência copa x porta-enxerto no desenvolvimento da mangueira. As alturas e os diâmetros das copas foram tomadas uma vez em 1981, quando as 210 plantas atingiram 15 anos de idade. As variedades de copas estudadas foram as seguintes: Extrema, Oliveira Neto, Carlota, Imperial, Pahiri e Bourbon. Os porta-enxertos utilizados foram Espada, Extrema, Olivara Neto, Carlota, Coco, Pahiri e Bourbon. Os dados foram analisados e a comparação das médias foi feita através do teste de Tukey em nível de 5% de probabilidade. O estudo mostrou que as variedades de copa, Olivara Neto, Extrema e Bourbon atingiram uma altura e um diâmetro maior que as demais variedades. The aim of this paper was to investigate the influence of the combination tree crown + rootstock on mango tree performance. The trees were selected according to height and crown diameter, measured once in 1981, using 210 trees, 15 years old at the beginning of the experiment. The Extrema, Espada, Oliveira Neto, Carlota, Bourbon, Coco and Pahiri varieties were used as rootstock and Extrema, Pahiri, Imperial, Oliveira Neto, Cariota e Bourbon were utilized as scions for tree crown development. Data were analysed by classical statistics, comparing means through the Tukey test, at a probability level of 5%. The crowns Oliveira Neto, Extrema e Bourbon showed the highest heights and diametres.

Bulbos de mesmo ciclo, com pesos e tamanhos próximos, apresentaram comportamentos semelhantes para a produção de flores, bulbos e cormilhos. Os bulbos maiores, tipos 1 e 2, tiveram melhor rendimento de flores, bulbos e cormilhos que os demais tipos, decrescendo esse rendimento com a redução do tamanho dos bulbos por unidade plantada. Em função do peso plantado, as unidades menores apresentaram melhor desempenho.

Para todos os cultivares, as plantas semeadas em dezembro cresceram mais e desenvolveram-se com maior rapidez que as plantas semeadas em maio; entretanto, as produções das plantas semeadas em maio foram maiores e a qualidade de seus frutos foi superior. Tanto para as plantas semeadas em maio como para as semeadas em dezembro, 'Santee' apresentou produções baixas e frutos de má qualidade. 'Aodai' foi o cultivar mais produtivo e seus frutos foram os de melhor qualidade. As produções dos demais cultivares foram equivalentes. 'Verde Paulistano' apresentou a produção mais tardia. 0 comportamento de 'Marketer' foi pouco afetado pelas variações ambientais. As maiores produções de todos os cultivares, nas duas é poças, foram obtidas entre a terceira e a penúltima colheitas. Foram encontradas correlações positivas entre a produção de cada colheita e a produção total, entre a produção total e a produção comerciável, entre o número de frutos e seu peso, entre produção e a altura da planta e entre produção e número de ramos laterais da planta. A relação entre produções comerciável e total e o peso médio dos frutos diminuíram no final do ciclo das plantas. Plant development and fruit production of cucumber cultivars 'Marketer IAC- 2 2 0 5 ' , 'Palomar IAC- 3 0 5 0 ' , 'Santee IAC- 2 4 4 1 ' , 'Verde Paulistano IAC-1336' and 'Aodai 1 - 4 3 2 1 ' were compared under two sowing dates, 5 t n of May and 5 t n of December of 1970 in Campinas, SP, Brazil, in a Yellow Red Latossol. Air temperature ranged from 1 2 , 0°C to 26, 8°C in the first period of culture, and from 18,5°C to 30,2°C in the second period. Adequate cultural practices were provided. When the first female flower appeared in the field, insecticides and fungicides applications were interrupted. For all cultivars, yields were higher and fruit quality was better in the first period of culture. Both in May and December cultures, plants have concentrated their highest yields between the third and the penultima te harvesting dates. 'Santee' presented low yields and the quality of its fruits was poor. 'Aodai' showed the best results as to fruit yield and fruit quality. Yields of the other cultivars were similar. 'Verde Paulistano' presented the latest fruit production. 'Marketer' showed a relatively uniform behaviour in both periods of culture. There were found positive correlations between yield in each harvesting date and total yield, total yield and marketable yield, number of fruits and fruits weight, plant height and yield, and number of lateral branches and yield. The relation between marketable and total yield, and fruit average weight, decreased at the end of the plants cycle.

A profundidade de plantio dos cormilhos influi na produção e qualidade do material de propagação. Em maiores profundidades, o peso médio por unidade produzida é maior. Para produzir bulbos dos tipos jumbo até o tipo 5, a profundidade de 7,3 cm foi a melhor. A profundidade de 5,6 cm foi melhor para quantidade. Maiores profundidades produzem menor cormilhos. The depth of planting cormels has influence on production and quality of propagation material. In bigger depth the average weight per unity planted is bigger. For production of corms type: jumbo untill type 5 the depth of 7.3 cm was the best one. The depth of 5.6 cm was the best for quality. Bigger depth produce less cormels.

Foi realizado no Campo Experimental do Setor de Horticultura da ESALQ, Piracicaba - SP, um experimento com a finalidade de verificar o efeito do linuron, cloroxuron e clorobromuron no controle de plantas daninhas na cultura da cenoura cv. "Kuroda". Foram testadas as dosagens mínima e máxima recomendadas pelos produtores dos herbicidas, em pré e pós-emergência das plantas daninhas. O linuron, tanto em pré com em pós-emergência, foi o mais eficiente, e o clorobromuron também deu bons resultados. O menos eficiente foi o cloroxuron a 6 kg/ha (dosagem mínima). Os herbicidas não conseguiram impedir o desenvolvimento das plantas daninhas até o final da cultura, havendo necessidade de se aplicar, talvez, uma outra dosagem após 40 dias de semeadura de cenoura.

O presente trabalho foi desenvolvido no Departamento de Agricultura e Horticultura da ESALQ, Piracicaba, tendo como objetivo estudar o crescimento da cultura da berinjela. Foram retiradas 14 plantas de uma cultuta de berinjela, cv. Florida Market, com uma população de 9.926 plantas por hectare. As plantas foram submetidas à análise de crescimento, de acordo com os métodos de Williams e Blackman & Wilson. A berinjela cresce vagarosamente durante a primeira fase, crescendo rapidamente a partir dos 42 dias após o transplante. A atividade fotossintética varia com a idade da planta, atingindo o ponto máximo ao redor dos 28 dias após o transplante.

). A nespereira (Eriobotrya japonioa Lindley) tem o habito de produzir numero elevado de frutos, de modo que o seu desenvolvimento natural resulta em produto de baixo valor comercial. Os poucos autores que trataram da cultura dessa frutifera mencionam a conveniencia de reduzir a carga dos frutos, porem, uns nao definem a intensidade com que deve ser feito o desbaste, outros indicam-na sem uma comprovacao experimental. Assim, Bailey (

Em condições de campo, borbulhas de laranja 'Pera' foram enxertadas sobre porta-enxertos de limão 'Cravo'. As alturas de enxertia utilizadas foram 5, 10, 20 e 40 cm acima do colo dos porta - enxertos nas exposições norte, sul, leste e oeste. Utilizou-se como método de forçamento do enxerto, o corte parcial do porta-enxerto pouco acima da enxertia com envergamento (pique). As alturas e as exposições de enxertia não afetaram o pegamento dos enxertos. Ovigor das mudas não foi afetado pelas exposições de enxertia, mas foi pelas alturas. As alturas de 5 e 10 cm promoveram maior desenvolvimento e maior diâmetro da haste principal do enxerto. 'Pera' sweet orange budwood was budded on fieldgrown Rungpur lime seedlings. Compared budding heights were 5, 10, 20 and 40 cm and budding expositions were north, south, east and west. The forcing method was lopping. There were no effects of height or exposition on bud take. Vigours of the plants, however, was affected by budding height. Budding heights of 5 or 10 cm induced the longest axes and the heightest diameters.

). A "mancha arro-xeada" constitui um dos problemas mais graves da cultura de nespereira no Estado de Sao Paulo- Trata-se de um disturbio que afeta a epiderme dos frutos, produzindo manchas de coloracao pardo-arroxeada e depreciando o aspecto do produto, que tem a cotacao drasticamente reduzida (

The author carried out a study on the behavior of cabbage for a period of two years (1952 and 1953). From the results obtained it was concluded that, cabbage, Brassica oleraceae, var. capitata, developed better during the cooler season of the year, that is, from April to June and, the yield decresed from the beginning to the end of the sowing time, that is, from April to Ocotber.

The author studied the possibility of propagating "Samambaia de Metro" Polypodium Subauriculatum, by means of spores, since vegetative multiplication is hard to obtain for large numbers of plants. Five treatments were tried, with 4 replications. I - Coarse "Flores Floor" and fine "Flores Floor". II - Coarse Flores Floor and moss. III - Coarse sand, Flores Floor and brick powder VI - Coarse sand, Flores Floor and brick powder V - Coarse sand and Flores Floor. The best germination was obtained with treatment V (Coarse sand et the boltom), topesed by Flores Floor. The pots were permanently kept on a tray pul of water, in a Greenhouse. This method provided over 4.000 offspring, which at 2 ½ years of age were of a size mitable for ornamental use.

O presente trabalho foi realizado em Piracicaba, São Paulo, Brasil. Os autores fizeram observações sôbre a posição que as gemas ocupam na base das bainhas das fôlhas da bananeira e às quais estão associadas. Utilizaram o cultivar Musa (Grupo AAA, Sub-Grupo Cavendish) "Nanicão", classificado de acôrdo com a nomenclatura de SIMMONDS (1966). Chegaram às seguintes conclusões: 1. As gemas associadas às bases das bainhas foliares estão colocadas em sua metade esquerda. 2. A metade direita das bainhas encobre as gemas colocadas mais internamente no caule da bananeira. 3. A disposição das gemas no caule é função da filotaxia da planta. In this paper, result of studies conducted in Piracicaba, São Paulo, Brazil, the authors made observations about the position of the buds at the base of the leaf sheaths to which they are associated. They used the banana plant variety Musa (AAA Group, Cavendish Sub-Group) "Nanicão", classified according to SIMMONDS' nomenclature (1966). The following conclusions were drawn :(1) The buds at the base of the leaf sheaths are found on the left, at lateral position on the sheaths. (2) The right side of the sheaths covers the younger buds which are placed more internally on the banana stem. (3) The position of the buds in the banana stem is a function of the phyllotaxy of the plant.

This paper brings to light new data on the absence of influence of lunar phases on the preservation of bamboo sticks. The author cut down for one and a half years (from - June 18, 1947 to December 30,1948) bamboos in every phase of the moon. With part of the sticks obtained a fence was built; the rest v/as kept under shelter. In the fence there were: 5 whole sticks with no preservative, 5 whole sticks with thanalith, 5 halved sticks with no preservative, 5 halved sticks with thanalith, all buried 10 centimeters in the soil. An equal number of the same types and in the same fence were kept upright 10 centimeters above the soil. Under shelter, in a shed, there was another group of sticks, 10 of each of the same four types. After 5 1/2 years no damage was observed in the fence for any treatment or any phase of the moon. On the other hand, for those bamboos kept under shelter the following numbers of perforated sticks were observed. Number of perforated sticks after 5 1/2 years Without Thanalith Thanalith Date of cutting Phase of the moon Whole Halved Whole Halved 8 - 25 - 47 Prime 0 3 0 0 9 - 29 - 47 Full 0 3 0 0 10 - 7 - 47 Wane 0 3 0 0 10 - 14 - 47 New 2 4 0 0 10 - 29 - 47 Full 0 5 0 0 11 - 6 - 47 Wane 3 3 0 0 11 - 13 - 47 New 0 1 0 0 4 - 1 - 43 Wane 3 5 0 0 8 - 27 - 48 Wane 1 3 0 0 10 - 10 - 48 Prime 1 3 0 0 Totals 10 36 0 0 So, among the 400 sticks kept under shelter, after 5 1/2 years, only 46 were perforated, all among those withe no preservative. No influence of lunar phase at cutting down of sticks seems to be present.

The author carried out an experiment of watering of lettuce (Lactuca sativa L.) in the vegetable garden of the Escola Superior de Agricultura "Luiz de Queiroz", with soil of the type know as "terra roxa". Eight treatments, with 4 replications, were used, divided into 3 groups, as follows: Group A - Watering once a day, late, in the afternoon, with 5, 10 and 15 liters per square meter; Group B - Watering twice a day, with 10 and 15 liters per square meter, one half in the morning, one half late in the afternoon; Group C - Watering as in group A, but with a 0.1% Chilean nitrate of soda, every 3 days. The size of plots was 2,0 x 2,0 meters. The means obtained, with their respective standard errors, were the following: Group A- (4295 ± 53 gm.) 5 lit./sq.m. 4120 ± 92 gm. 10 lit./ sq. m. 4248 ± 92 gm. 15 lit./sq.m. 4518 + 92 gm. Group B- (4091 ± 65 gm.) 10 lit./sq.m. 3960 ± 92 gm. 15 lit./ sq. m. 4223 ± 92 gm. Group C- (4490 ± 53 gm.) 5 lit./ sq. m. 4300 ± 92 gm. 10 lit./sq.m. 4480 ± 92 gm. 15 lit./sq.m. 4690 ± 92 gm. Differences between groups, as well as within them were significant, even if within groups B the 5% probability level was not quite reached.

Foi realizado no Campo Experimental do Setor de Horticultura da ESALQ, Piracicaba, um experimento no sentido de verificar os efeitos de linuron, clorobromuron e cloroxuron sobre a cultura da cenoura. Foram testadas as dosagens mínima e máxima recomendadas pelos produtores dos herbicidas, em pré e pós-emergência das plantas daninhas. Os herbicidas não interferiram na parte aérea da cenoura. Em geral, os tratamentos em pré-emergência deram maior produção de parte aérea, raízes e raízes comerciáveis que os tratamentos em pós-emergência. Tanto o linuron como o clorobromuron deram bons resultados, sem interferir na produção, enquanto que a dosagem mínima de cloroxuron deu menos produção, devido ao pequeno controle das plantas daninhas. It was conducted an experiment in the Experimental Field of Horticulture Section of ESALQ, Piracicaba, to verify the effects of linuron, chlorobromuron, and chloroxuron on carrot crop. It was tested the minimum and maximum rates recommended by herbicide productors in "pré" and post-emergence of weeds. The herbicide did not interfy over carrot overground part. Generally, pre-emergence treatments gave higher production of overground part, roots and commercial roots than post-emergence treatments. Both linuron and chlorobromuron gave good results, without interfy over production, while the minimum rate of chloroxuron gave the least production due to poor weed control.

As densidades de plantio estudadas foram de 233.333, 175.000 e 116.667 plantas por hectare, obtidas da utilização dos seguintes espaçamentos: 0,15 m x 0,20 m; 0,20 mx 0,20m e 0,30 m x 0,30 m. Scania Red foi o cultivar utilizado. Os parâmetros analisados foram o número de cravos com cálice inteiro e rachado por planta e por hectare, bem como comprimento da haste com flor, peso da haste com flor e diâmetro da corola. Concluiu-se que o aumento da densidade de plantio ocasionou um acréscimo na produção de cravos com cálice inteiro por hectare, uma diminuição da produção de cravos com cálice rachado por planta, uma diminuição do peso da haste com flor e uma diminuição do diâmetro da corola. Não houve influência da densidade de plantio sobre a produção de cravos com cálice inteiro por planta, sobre a produção de cravos com cálice rachado por hectare e sobre o comprimento da haste com flor. The influence of density of planting on quality of the flower in carnation plants grown in vinil houses was studied. Planting densities of 233,333, 176,000 and 116,667 plants per hectare were obtained by using planting spacings of 0.20m between rows and 0.15m, 0.20m and 0.30m between plants in the rows. Data on number of flowers with perfect calyx and on number of flowers with splitted calyx both per plant and per hectare were taken, as well as on flower plus flower stalk weight and on length and diameter of corola. As far as planting densities are concerned, there was an increase in production of flowers with perfect calyx per hectare and a decrease in production of flowers having splitted calyx per plant, flower plus flower stalk weight and corolla diameter as planting density increases. There was no influence of the planting density on the production of perfect calyx flower per plant, splitted calyx flower production per hectare and flower plus flower stalk length. UNESP F.C.A.

Os cormilhos tipo 7 produziram bulbos e cormilhos dos tipos de 1 a 8 em maior quantidade que o tipo 8 e os bulbos tipos 1, 2, 3, 4 e 5 mais pesados. Os cormilhos tipo 8 também produziram bulbos e cormilhos dos tipos 1 a 8, porém seus cormilhos foram mais pesados que os cormilhos produzidos pelo tipo 7. Cormels type 7 produced corms and cormels type 1 to 8 in greater quantity than type number 8 and corms type 1, 2, 3, 4 and 5 were heavier. Cormels type 8 also produced corms and cormels type 1 to 8, however their cormels were heavier than cormels produzed by type 7.

Bulbos de 2° ciclo, tipo jumbo, com 84 g/unidade e tipo 1, com 35 g/unidade, foram comparados. Verificou-se que: o tipo jumbo teve melhor rendimento de: peso de bulbos; número de bulbos; comprimento da haste floral; comprimento da espiga floral e hastes florais de melhor qualidade. Otipo 1 apresentou melhor rendimento para peso de bulbos plantados por peso de bulbos e cormilhos colhidos. Corms of 2nd cycle, type jumbo with 84 g/unity and type 1 with 35 g/unity were compared. It was verified that: type jumbo had better profit in the production of: weight of corms, number of corms, lenght of stipe, lenght of spike and stipe of better quality. The type number 1 showed better profit for weight of corms planted by weight of corms and cormels harvest.

O presente trabalho teve como objetivo estudar a influência de diferentes densidades populacionais de craveiros, cultivados em casa de vegetação, sobre a produção das flores. As densidades populacionais estudadas, 233.333, I75.000 e 116.667 plantas por hectare, foram obtidas pela utilização de espaçamentos de respectivamente 0 ,15 m x 0,15 m; 0,20 m x 0,20 m e 0,30 m x 0,20 m. Scania Red foi o cultivar utilizado. Concluiu-se que o aumento da densidade de plantio causou um acréscimo na produção total de cravos por área e uma diminuição da produção de cravos por planta. The influence of density of planting on flower production of carnation plants grown in vinil houses, was studied. Planting densities of 233,333; 175,000 and 116,667 plants per hectare were obtained by using planting spacings of 0.20 m between rows and 0.15 m, 0,20 m and 0.30 m between plants. Data were taken on total number of flowers per plant and per hectare. As far as planting densities are concerned, there was an increase of total flower production per hectare and a decrease of slower production per plant.

As mudas utilizadas no experimento foram plantadas em setembro de 1971, sendo cinco os tratamentos: planta matriz sem rebento, planta matriz com seleção dos rebentos, de janeiro, março e maio de 1972 e planta matriz com todos os rebentos. Os resultados obtidos revelam influência da época da seleção dos rebentos sobre: diâmetro do pseudo-caule e lançamento de folhas no mês de abril, durante a fase de desenvolvimento vegetativo; número de dias decorridos do plantio ao florescimento, número de plantas florescidas no mês de julho, número de folhas, altura e diâmetro do pseudo-caule, número de pencas por cacho e altura do rebento na fase do florescimento. The primary objetive of this study was to determine the effect of time of selection of suckers on the development of banana matriz plants (Musa cavendishii Lam. cv. Nanicão). The treatments were as follows: a. matrix plant without suckers; b. matrix plant with January suckers; c. matrix plant with March suckers; d. matrix plant with May suckers; e. control matrix plant: no suckers removed by pruning. The results of this study were: 1. Fewest leaves were produced in the control matrix plants in April; 2. Time of selection of suckers affected the flowering stage more than the vegetativa stag; 3. Flowering os the matrix plant (a) with no suckers and (c, d) with March and May suckers was augmented, and production of bunches with a greater humber of hands was stimulated; 4. matrix plant with January suckers and control matrix plant attained greater height of suckers than all other matrix plants treatments.

Três doses de N, P e K foram testadas em culturas de gladíolos (Gladiolus grandiflorus cv. 'Perusi') provenientes de três tamanhos diferentes de bulbos (Nº 3, Nº 1 e Jumbo). Todos os tratos culturais necessários foram dispensados aos experimentos cuja instalação se deu em um solo podzolizado da Cooperativa Agrícola de Holambra, em Jaguariúna - SP. Estudaram-se os efeitos de adubação sobre produção de flores, produção de bulbos e de bulbilhos. A resposta do gladíolo aos níveis de fertilização variou bastante com o tamanho de bulbo plantado. São discutidos os efeitos de cada nutriente sobre as características estudadas. Studies on N, P. K fertilization of Gladiolus (Gladiolus grandiflorus, cv. 'Perusi'). At the Agricultural Cooperative of Holambra, Jaguariúna SP, experiments with gladiolus were conducted with the objective of studying the effects of increasing dosis of N, R and K on the floral stems and corms production. The response of gladiolus to nitrogen, phosphorus and potassium varied with the size of the corm that was planted. The effects of each nutrient on several characteristics of plants are discussed.

This experiment was conducted in order to verify a possible translocation of substituted urea herbicides in soil. Bioassay was done using tomato as plant. The soil tested was from a carrot culture with high organic matter and clay content. The herbicides tested were linuron, chloroxuron and chlorobromuron, at two dosages: minimum and maximum recommended by industries. The results indicated that there was not neither lateral' translocation nor through 30 cm depth. The possible cause was the high clay and organic matter content of the soil. O presente experimento foi conduzido para verificar uma possível translocação de herbicidas do grupo das uréias substituidas no solo. No bioensaio foi utilizado o tomateiro como planta teste. o solo testado foi de uma cultura de cenoura, com alto teor de matéria orgânica e argila. Os herbicidas testados foram o linuron, cloroxuron e clorobromuron, em 2 dosagens: a mínima e a máxima recomendadas pelos produtores. Os resultados indicaram que não houve translocações lateral e através de uma profundidade de 30 cm. a possível causa foi o alto teor de matéria orgânica e argila.

The authors study the insect population that visit the mango trees and search for their pollinizing activity. Prior operations showed that very few bees (Apis mellifera) visited the flowers of mango trees. It was known that the percentage of fecundation is low (Simao 1955), Popenoe (1929), Spencer and Kennard (1955), Lynch and Mustard (1955), Ruehle and Ledin (1955), so that the authors wented to Know if insects could be responsible for this. Insects were collected from mango trees, belonging to 10 orders, which, on the whole are not pollinizing agents. Bees were not collected, 21% were Hymenoptera, 20% were Diptera, 13% Hemiptera, 10% Coleoptera, 3% Blattariae and smoller percentages belonged to other orders.

The author studied the storage of seeds of mango trees with the aim of Keeping high its ability of germination. Seven means of storage were tried, with two temperatures: environment temperature (22 to 27 degrees Centigrade) and cold store room (5 degrees centigrade). The methods of storage tried were: 1 - The frewit kept complete. 2 - Seeds taken within the stone. 3 - Seeds taken out of the stone. 4 - Stones heated with a Fungicida (Zineb). 5 - Stones cut laterally and heated with a fungicide (Zineb). 6 - Seeds (out of sones) heated with Zineb. 7 - Stones steatified with sand. The best results were obtained for seeds kept within whole fruits, probably owing to protection provided by outer layers. The use of fungicide imposed the sanitary aspect of seeds and stones. Storage in cold store room (5 degrees Centigrade) injured the seeds and stones in all cases. Germinating power was kept high up to 70 days for complete fruits. It seems that biggers fruits were more favorable to keep high the ability of theirs seeds to germinate.

The aim of this paper is the study of moon effects on ten different crops divided in four groups: 1) salad and cole crops (lettuce, endive, cabbage, cauliflower); 2) root crops (beet, carrot, radish, turnip); 3) bulb crops (onion); 4) solanaceous fruits (eggplant). The design of the experiment was randomized blocks, with four replications, the different treatments being the four phases of the moon. The analyses of variance are given in the work of Simão (1953) and the analises of the mean in tables 1 to 2. The main conclusions are: 1) No difference in production were found related to different moon phases, even it the crops supposed to be sensible to moon effects. 2) In a few cases, where some increase in production was observed, such increase could be atributed by other apents 3) The agents supposed to interfere with increase in production were temperature and photoperiodism, rather than moon phases. 4) The most sensible crops to low temperature, during the night, were: lettuce, endive, cauliflower, cabbage, carrots, turnips and radish. 5) The most sensible crops to both low temperature and photoperiodism were: onion and beet. 6) The moon phases supposed to have opposed effects, namely full-moon and half-moon, gave mixed results sometimes both giving the best yield simultaneously and sometimes giving the poorest crops. 7) As a final conclusion, no moon effects could be detectable in the present experiment.

Th objective of this study was to determine the effects of selection time suckers on the growth and production of banana matrix plant (Musa cavendishii Lamb) cv, Nanicão. The trial was carried out at the Escola Superior de Agricultura "Luiz de Queiroz", Piracicaba (SP) Brazil, from September, 19, 1971, to January 31, 1973. A randomized blocks design was used with five treatments and five replications The treatments were as folows: 1. Matrix plant whitout suckers; 2. Matrix plant with January sucker; 3. Matrix plant with March sucker; 4. Matrix plant with may sucker; and 5. Control matrix plant with all suckers. The results of study were: a. Matrix plant with May sucker incresead the time from planting to flowering as compared with January sucker, no sucker, and March sucker; control matrix plant with all suckers delayed flowering time as compared with matrix plant witch March sucker. b. The pseudostem circunference at flowering time were similar in all treatments except treatment with January sucker and control matrix plant with all suckers; these treatments have resulted in a markerd reduction in circunference of pseudostem at flowering time. c. Production cycle periods were similar for treatments no sucker, January and May sucker; the production cycle was smaller with March sucker and larger in control matrix plant with all suckers. d. The number of leaves in harvesting time was highest in May sucker as compared with January sucker and control matrix plant with all suckers; the treatments no sucker and March sucker had highest number of leaves as compared control matrix plant with all suckers. e. Control matrix plant with all suckers had lower average bunch weight as compared with treatments with no sucker, March and May sucker. f. These was no significance diference on pseudostem circunference at flowering and harvesting time, "hands" and "finger" number per bunch. No presente trabalho foram feitos os tratamentos: planta matriz sem rebentos; planta matriz com rebentos de janeiro, março e maio e testemunha com todos os rebentos, sendo estudada sua influência no desenvolvimento e produção da planta matriz de bananeira. Os resultados mostraram diferença significativa entre os tratamentos, com relação ao número de dias do plantio ao florescimento, ciclo de produção, número de folhas na colheita e peso do cacho. Não houve diferença significativa em relação ao diâmetro do pseudo-caule no florescimento e colheita, número de pencas e frutos.

Efeitos de parcelamento de adubação nitrogenada e potássica foram estudados na cultura de Gladiolus grandiflorus, L., cv. 'Friendship', no que concerne a produção de bulbos, bulbilhos e hastes florais. Houve influência do parcelamento sobre número e peso de bulbos e bulbilhos e sobre comprimento de haste floral do gladíolo. Em geral o nitrogênio influiu sobre número de bulbos e de bulbilhos, enquanto o potássio influenciou em seu peso. The presente experiments had as it objectives the cultivation of Gladiolus grandiflorus, L., cv. 'Friendship', in field conditions, studying the effects of parcelling of nitrogenous and potassic fertilization, in relation to corms, cormels and floral spikes production. Theree were effects of parcelling fertilization on number and weight of corms, cormels and floral spikes. In general nitrogen influences more on number of corms and cormels while potassium influences on its weight.

During 1952 and 1953 the author observed that radish, Raphanus sativus, L, developed rapidily in the warmer and damper period of the year and endured the lower temperatures. The yiel of leaves counted from 20 to 40% of the plant weigth.
