Abstract

A serapilheira desempenha funções imprescindíveis para a manutenção dos ecossistemas, por isso, seu estudo é indispensável. Entretanto, os trabalhos publicados têm apresentado variações consideráveis quanto à periodicidade de amostragem e métodos de coleta. Assim, objetivou-se quali-quantificar a produção científica e as instituições de origem das publicações sobre serapilheira no Pará nos últimos 40 anos (1980-2019). Constatou-se 34 artigos científicos, destes a maioria (38%) foi publicado no período de 2015-2019. Em 21,28% dos trabalhos houve parcerias com pesquisadores internacionais e 8,51%, interestaduais. 91,43% das publicações científicas foram oriundas de instituições públicas, com destaque para Universidade Federal Rural da Amazônia (27,66%). Na autoria, predominaram profissionais concomitantemente com estudantes de pós-graduação. Encontrou-se trabalhos em apenas 16 municípios, com destaque para Paragominas, Castanhal e Belém. A avaliação da deposição ocorreu em 82,35% dos estudos, o estoque foi representado por 17,65%. A deposição de serapilheira nos ecossistemas variou de 4,56 ± 1,71 Mg ha-1 ano-1 a 8,51 ± 1,76 Mg ha-1 ano-1 para ecossistemas de pastagem e de floresta aluvial. No estoque, devido à insuficiência de trabalhos, só foi possível definir o padrão para floresta secundária, com média de 6,33 ± 2,79 Mg ha-1. A concentração de nutrientes da deposição de serapilheira nos ecossistemas deteve a seguinte ordem de magnitude: N>Ca>K>Mg>P. Nesse contexto, observou-se a necessidade da intensificação de pesquisas sobre serapilheira em diferentes ecossistemas no estado do Pará, sobretudo nos 128 municípios com ausência de publicações.

Abstract

A produção e decomposição da serapilheira é importante no funcionamento e na dinâmica de um ecossistema florestal, associando variáveis climatológicas à biomassa. Com isso, investigou-se o estoque de serapilheira em função da sozanalidade dos elementos do clima em uma floresta sucessional na Amazônia oriental. O estudo foi conduzido em uma floresta sucessional, na Região Metropolitana de Belém (RMB), Pará. No ecossistema foi realizada uma amostragem aleatória em três transectos alocados ao longo da perpendicular da linha de borda de 50 m. A análise do efeito da sazonalidade dos elementos do clima nas propriedades físicas (volume, espessura, densidade e massa seca) e no carbono da serapilheira foram realizadas utilizando o teste t student e ANOVA do teste F a 5% de significância. A precipitação (495,2±125mm e 109,8±60mm) e a umidade relativa do ar (89,0±1,7% e 79,6±2,8%) apresentaram diferença estatística na sazonalidade (p<0,05), diferente da temperatura (27,1±0,2ºC e 27,6±0,3ºC) que não houve diferença. As variáveis da serapilheira não foram influenciadas pela sazonalidade dos elementos do clima e não diferiram estatisticamente entre os períodos chuvoso e menos chuvoso, respectivamente: quantidade de serapilheira acumulada (16,46±4,17 Mg ha-1 e 13,91±7,61 Mg ha-1), estoque de carbono da serapilheira (7,9±2,0 Mg ha-1 e 6,6 ± 3,61 Mg ha-1), volume (26,21±0,92cm3 e 24,88±0,92cm3), espessura (4,19±0,92cm e 3,99±0,95cm) e densidade (0,041±0,92g/cm3 e 0,034±0,92 g/cm3). A sazonalidade dos elementos do clima não apresentou variação considerável a ponto de alterar as propriedades físicas e o carbono da serapilheira.

Abstract

Water scarcity in the world is a problem diagnosed especially in countries with large semi-arid regions such as Brazil. Research has been conducted with a view to making use of saline waters as an input for cultivation, particularly in hydroponics, with especial focus on lettuce, the most prominent leafy vegetable in Brazil. The objective of this study was to evaluate the development of lettuce in a semi-hydroponic system fertigated with saline water and under foliar fertilization with biofertilizer. The present study was carried out in a greenhouse located in the experimental area of the Department of Environmental and Technological Sciences (DCAT) of the Federal Rural University of the Semi-Arid Region, in the municipality of Mossoró, RN, Brazil. The experimental design was a randomized complete block design, with treatments arranged in a 2 x 4 factorial scheme, with 4 replicates, two salinity levels of the water used to prepare the nutrient solution (0.5 and 3.5 dS m-1) and four biofertilizer concentrations (0, 20, 40 and 60%) applied by foliar spraying. The evaluated characteristics were: shoot diameter, stem diameter, number of leaves, fresh mass, dry mass, leaf succulence, leaf area and specific leaf area. The use of saline water to prepare the nutrient solution reduces fresh mass and dry mass production in the lettuce crop. The biofertilizer can be applied through the leaves at concentration of up to 20%, promoting greater plant growth. [ABSTRACT FROM AUTHOR]

Abstract

The objective of this work was to evaluate the litter production and decomposition in three mahogany (Swietenia macrophylla King) systems in the northeastern Pará region. The treatments were: T1 - mahogany consortium with forest species; T2 - homogeneous plantation of mahogany; and T3 - secondary forest enriched with mahogany. Collectors of 1 m2 opening were used to collect the litter produced monthly for a year. Evaluations were performed monthly for one year. The decomposed litter was estimated by means of the relation between the litter produced and the litter accumulated in the soil. The litter deposition dynamics did not present a significant correlation with variations in rainfall and average temperature. The homogeneous mahogany plantation produced more litter (5.6 Mg ha-1 year-1) with the leaf fraction being the most representative. The decomposition and renewal of litter did not differ between the three mahogany environments. The pure Brazilian mahogany plantation produced a larger amount of litter compared to the other planting systems, with the leaf fraction presenting the highest percentage contribution.

Author

Marques da Silva, Maristela, de Assis Oliveira, Francisco, Marques da Silva, Maristela, and de Assis Oliveira, Francisco

Abstract

O sistema de produção desenvolvido pela maioria das famílias é o sistema de produção do corte queima, onde as áreas são derrubadas, queimadas e cultivadas, e depois de um tempo de uso, essas áreas são abandonadas iniciando um processo de regeneração natural, com formação das florestas secundárias. Esse artigo propõem-se a discutir a importância das florestas secundária nos estabelecimentos familiares no município de Altamira , enfocando um breve resgate do processo histórico de ocupação da região e o papel das florestas secundárias na agricultura familiar no município de Altamira, Sudoeste do Pará., The production system developed by most families is the system production cut burning, where the areas are cleared, burned and cultivated, and after a while of use, these areas are abandoned initiating a process of natural regeneration and the formation of secondary forests. This paper proposes to discuss the importance of secondary forests on family farms in the municipality of Altamira, focusing on a brief historical redemption process of occupation of the region and the role of secondary forests on family farms in the municipality of Altamira, Pará.

Abstract

This study was conducted at greenhouse of the Department of Soil and Rural Engineering of the Center of Agrarian Sciences/UFPB, located in Areia, PB, Brazil, with the objective of evaluating the effect of four doses of phosphorus (0, 40, 80 and 120 kg of P2O5 ha-1) and four levels of available soil water (20, 40, 60 and 80%) on the foliar area, height plant and root dry biomass of the corn (Zea mays L.) crop. The experiment was carried out in a randomized block using a 4 x 4 factorial scheme, with three replications. The experimental unit was represented by a plastic vase with 9 kg of soil of the surface layer (0 - 20 cm) of an Oxisol. The analysis of variance showed highly significant effect (p ≤ 0.01) of the treatments with phosphorus as well as of the ones of available water in the soil, on the results of plant height up to 30 and 90 days after emergence (DAE); there was not effect of the phosphorus treatments inside of the water levels for the foliar area and root dry biomass up to 90 DAE. It was observed that in the levels of 80% and 60% of the available water in the soil, for the crop to reach its maximum height there would be need to apply to the soil doses of P2O5 superior to 120 kg ha-1, also standing out that for the corn crop to respond significantly to phosphorus doses it is necessary a minimum amount of 40% of available water in the soil., O presente trabalho foi conduzido em casa-de-vegetação do Departamento de Solo e Engenharia Rural do CCA/UFPB, Areia, PB, com o objetivo de se avaliar quatro dosagens de fósforo (0, 40, 80 e 120 kg de P2O5 ha-1) e quatro níveis de água no solo (20, 40, 60 e 80% da água disponível) sobre a área foliar, altura de planta e biomassa seca da raiz da cultura do milho (Zea mays L.). Usou-se o delineamento de blocos ao acaso em esquema fatorial 4 x 4, com três repetições. A unidade experimental foi representada por um vaso plástico com 9 kg de solo coletado na profundidade de 0 a 20 cm do perfil de um Latossolo Amarelo. Segundo a análise de variância, ocorreu efeito altamente significativo (p ≤ 0,01) tanto para os tratamentos com fósforo como para os de água disponível no solo, sobre os resultados de altura de planta aos 30 e 90 dias após a emergência (DAE); não houve efeito dos tratamentos de fósforo dentro dos níveis de água para a área foliar e a biomassa seca da raiz aos 90 DAE. Observou-se que nos níveis de 80% e 60% da água disponível no solo para a cultura atingir a altura máxima, haveria necessidade de se aplicar ao solo doses de P2O5 superiores a 120 kg ha-1, ressaltando também que para que a cultura do milho responda significativamente às dosagens de fósforo é preciso uma quantidade mínima de 40% de água disponível no solo., El estudio se realizó en casa por la vegetación del Departamento de Suelos y de Ingeniería Rural de la ECP / UFPb, Areia, PB, con el objetivo de evaluar cuatro dosis de fósforo (0, 40, 80 y 120 kg de P2O5 ha-1) y cuatro niveles de agua en el suelo (20, 40, 60 y el 80% del agua disponible) sobre el área foliar, altura de planta y biomasa seca de la raíz de la cosecha de maíz (Zea mays L.). Se utiliza para el diseño de azar en factorial 4 x 4 con tres repeticiones. La unidad experimental estuvo representada por un bote de plástico con 9 kg de suelo recolectadas en la profundidad de 0 a 20 cm del perfil de un Oxisol. Según el análisis de la varianza, fue muy significativo 0,01) para los tratamientos con el fósforo y el agua≤efecto (p disponible en el suelo, sobre los resultados de la altura de las plantas a 30 y 90 días después de la emergencia (DAE) , no hubo efecto de los tratamientos de fósforo en el agua a niveles de área foliar y la biomasa seca de las raíces a 90 DAE. Se observó que los niveles de 80% y el 60% del agua disponible en el suelo para el cultivo alcanza la máxima altura tendría que aplicar a la tierra de los niveles superior a 120 kg de P2O5 ha-1, también hizo hincapié en que para la cultura maíz responder significativamente a los niveles de fósforo que se necesita al menos el 40% del agua disponible en el suelo.

Abstract

α-Terpineol is a monoterpene with smooth muscle relaxant properties. In this study, its effects on the gastric emptying rate of awake rats were evaluated with emphasis on the mode by which it induces gastrointestinal actions. Administered by gavage, α-terpineol (50 mg/kg) delayed gastric emptying of a liquid test meal at 10 min postprandial. Hexamethonium or guanethidine did not interfere with the retarding effect induced by α-terpineol, but atropine and L-NG-nitroargi- nine methyl ester abolished it. In vagotomized rats, α-terpineol did not delay gastric emptying. In isolated strips of gastric fundus, concentration-effect curves in response to carbamylcholine were higher in magnitude after treatment with the monoterpene. α-Terpineol (1 to 2000 µM) relaxed sustained contractions induced by carba- mylcholine or a high K+ concentration in a concentration-dependent manner. This relaxing effect was not affected by the presence of L-NG-nitroarginine methyl ester, 1 H-[1,2,4]oxadiazolo [4,3-a]quinoxalin-1-one, tetraethylammonium, or atropine. Smooth muscle contractions induced by electrical field stimulation were inhibited by α-terpineol. In conclusion, α-terpineol induced gastric retention in awake rats through mechanisms that depended on intact vagal innervation to the stomach, which involved cholinergic/nitrergic signalling. Such a retarding effect induced by α-terpineol appears not to result from a direct action of the monoterpene on gastric smooth muscle cells. [ABSTRACT FROM AUTHOR]

Abstract

This research aimed to evaluate the yield and quality of tomato plants under different managements of salt stress by adopting the partial root-zone saline irrigation (PRSI) system. The experiment was conducted in a greenhouse at the Universidade Federal Rural do SemiÁrido (UFERSA), Mossor ó, Rio Grande do Norte (RN), Brazil. The experimental design was completely randomized, with six treatments and four replicates, totaling 24 plots. The treatments consisted of six different irrigation management regimes using low and high saline water (S1-0.5 and S2-5.0 dS⋅mL-1), applied with or without PRSI, such that one side of the root-zone was submitted to saline water whilst the other side was water low salinity irrigated. For treatments T1 (control), T2 (S2 water), and T3 (alternate irrigation system between S1 and S2, with a cycling period of 15 d for each one), the PRSI was not applied; T4 (irrigation with S1 and S2, adopting the PRSI system from phase II to phase IV), T5 (irrigation with S1 and S2 in phase II, alternating in phase III; in phase III the inversion of the remaining water was made until the end of phase IV), and T6 (irrigation with S1 and S2, adopting the PRSI system in phase II, with the water switched between low and high saline water every 15 days, remaining until the end of phase IV) treatments were under the PRSI. The number of fruit per plant, fruit weight, fruit longitudinal and transverse diameter, pulp firmness, soluble solids content, titratable acidity, pH, vitamin C, color relation (a*/b*), lycopene, and β-carotene were determined as parameters for the fruit yield and quality evaluation. Our findings reinforce the importance of the use of PRSI systems followed by irrigation managements without loss of product quality, such as demonstrated by T4 and T5 water managements.
