Abstract

The present study aimed to analyze the application of a seaweed biofertilizer as an attenuator of salt stress on the morphophysiology of scarlet eggplants. The experiment was carried out under protected conditions in Areia, PB, Brazil, using an incomplete factorial arrangement in a randomized block design with four replications and two plants per plot by adopting the Box Central Composite Design with five electrical conductivities of irrigation water – ECiw (0.50 – control, 1.15, 2.75, 4.35 and 5.00 dS m−1) and five concentrations of seaweed biofertilizer (0 – control, 1.45, 5.00, 8.55 and 10 mL L−1). The electrical conductivity of irrigation water at values starting at 0.5 dS m−1 negatively affected the growth of scarlet eggplants. Therefore, the crop is considered sensitive to salt accumulation. The increase in electrical conductivity of irrigation water negatively affected the morphophysiology of scarlet eggplants, with reductions higher than 10% at electrical conductivity values higher than 1.37 dS m−1. Biofertilization at 6.67 mL L−1 mitigates the effects of salt stress on the gas exchange variables and the phytomass accumulation of scarlet eggplants 60 days after sowing. The seaweed biofertilizer can be used to improve the physiological and morphological performance of scarlet eggplants. [ABSTRACT FROM AUTHOR]

Abstract

Northeastern region of India is endowed with variety of local vegetables that are highly nutritious and health-promoting. One of which is Solanum aethiopicum L which has a bountiful source of nutrients and bioactive chemicals. It has several pharmacological benefits and are used in indigenous medicine to treat various conditions. Nonetheless, the crop is highly perishable with a short shelf life (35days) which significantly contributes to postharvest losses. Techniques used to extend the shelf life of the crop are freezing, drying and refrigeration. The crop can be stored at low temperatures about 10-12oC. Fruits kept in perforated polyethylene bags had the longest shelf life. Important materials include polyethylene, polypropylene, and polystyrene are commonly used and coating can be applied to increase the crop’s shelf life. The crop has a huge potential in making value added products like pickles, dehydrated products and many more. However, concerns related to postharvest and production of the crop have not received equal attention due to scant research with the crop being neglected and underutilized due to lack of awareness and limited market. Considering the crop offers many advantages, popularization of the crop is essential but adapting to the bitter taste and flavor of the fruit could be challenging for the consumers. Consumer attitudes, views, and willingness to pay for products that have undergone particular post-harvest procedures require further investigation. Proper cultivation techniques, processing, value addition and marketing are required to surpass these hurdles.

Abstract

Solanum aethiopicum L. is indigenous to Africa and constitutes an important vegetable. Morpho-agronomic traits were used to study diversity among 44 accessions of S. aethiopicum groups to identify traits of high discriminatory ability and donor parents with specific or multiple traits for introgression and utilization in breeding programmes. Field experiments were conducted from 2008 to 2010. The principal component (PC) analysis of morpho-agronomic data indicated high discriminatory ability for fruit calyx length, fruit length and leaf length. On PC1, fruit length showed positive and significant correlation coefficients with leaf length, fruit calyx length and width. An independent association was recorded among fruit width, fruits per infructescence and seed yield (t/ha). Ordination (biplot) and grouping (dendrogram) revealed genetic variation and relatedness, phenotypic plasticity and geographical heterogeneity among the accessions within and among the clusters. Members of cluster 1 (group ‘c’) are a promising donor parent for multiple traits (earliness and fruit length), and members of group ‘b’ are superior for fruits per plant, fruits per infructescence and fruit infructescence per plant. Hybridization among distant clusters would provide an opportunity for bringing together gene constellations of diverse background. Earliness and fruit length were highly variable among the S. aethiopicum groups. The results are important for the breeding and selection of this crop. [ABSTRACT FROM PUBLISHER]

Dentre os fatores que podem prejudicar a produção de solanáceas, destacam-se as viroses e a infestação por insetos. Diante dos aspectos de grande importância descritos acima a tese foi dividida em dois capítulos. O capítulo 1, trata-se do primeiro relato de groundnut rigspot virus em jiló Brasil, na qual, anormalidades foram observadas em campos de produção de jiló (Solanum aethiopicum L.) no interior de São Paulo região de Itápolis. Sintomas de anéis necróticos e concêntricos foram observados em folhas e frutos, típicos da infecção por vírus. As plantas foram submetidas a extração de RNA total e RT-PCR. Os amplicons foram purificados e sequenciados, confirmando a identidade de 99% com GRSV vírus foi identificado como groundnut ringspot virus (GRSV). Testes biológicos foram realizados em Solanum melongena cv. Napolitana, S. melongena cv. Napoli, S. melongena cv. Roma, S. aethiopicum cv. Morro Grande, S. aethiopicum cv. Comprido Verde Claro, Datura stramonium, S. lycopersicum Mariana, Nicotiana tabacum “TNN”, N. tabacum Virgínia, Capsicum annuum ‘Magali R’ e S. americanum. Ao final de 30 dias, todas as espécies testadas apresentaram sintomas sistêmica, evidenciando a infecção viral. No capítulo 2 foi abordado o desempenho de espécies crípticas de Bemisia tabaci em cultivares de pimentão. Com a introdução da espécie Mediterranean no Brasil, também conhecida por biótipo Q, e tendo a informação de que ela é muito adaptada a cultura do pimentão e apresenta baixa suscetibilidade a diferentes inseticidas, foram testados genótipos de pimentão quanto ao desempenho e atratividade das espécies MEAM1 e MED. Os acessos IAC 1549, IAC 1551 e IAC 1544 apresentaram tolerância a espécie Mediterranean, por exibirem baixa eclosão de ovos, pouca emergência de adultos, e menor sobrevivência de insetos. Além disso, IAC 1549 e IAC 1551 foram pouco atrativos para MED. A espécie Mediterranean possui maior preferência e atratividade diante de MEAM1 em pimentão. A cultivar ‘Dahra R’ se destacou por apresentar baixa preferência por oviposição, pouca emergência de adultos e menor sobrevivência de MEAM1 e MED, além de, baixa eclosão de ninfas de MED. Dessa forma, conclui-se que existem materiais tolerantes a mosca-branca, ressaltando que o emprego de cultivares tolerantes podem ser uma alternativa aos produtores no manejo de mosca-branca, além disso, há genótipos com potencial de serem integrados em programas de melhoramento, buscando o desenvolvimento de novas cultivares tolerantes a moscabranca 001

Abstract

Genetic diversity among 70 "scarlet eggplant" (Solanum aethiopicum L.) entries from different geographical origins was assessed. Entries were firstly evaluated for the main morphologic traits and chlorogenic acid content. Standard statistics and multivariate analyses were utilized to assess the phenotypic diversity and grouping the entries. In addition, amplified fragment length polymorphism (AFLP) and simple sequence repeat (SSR) analyses were used to evaluate genetic relationships among entries. Differences between entries are highly significant for all descriptors. Principal component analysis (PCA) revealed that the first three components accounted for 74% of the total variance. Morphologic traits were associated with the first two components, while the third one was moderately correlated with the chlorogenic acid content. The observed similarity allowed identifying only three main groupings. The clusters obtained did not show any relationships with geographic origins and/or botanical groups. Matrices of genetic similarity from AFLP and SSR data were utilized in order to obtain a dendrogram. A large cluster included several entries from South America with limited rate of genetic variation was observed. On the contrary, higher amount of variation was observed in the cluster with entries from Africa, in which are also present in the accessions collected in Italy. These entries appeared always morphologically and genetically distinguishable from the others. These results provided additional information for the conservation, improvement and legal protection of the ecotype 'melanzana rossa di Rotonda', cultivated in Italy.
