Características qualitativas de genótipos de cebola

Objetivou-se, com o trabalho, avaliar alguns atributos de qualidade de diferentes genótipos de cebola (Allium cepa L.), cultivados em Mossoró-RN. O experimento foi realizado na horta experimental no Departamento de Ciências Vegetais da Universidade Federal Rural do Semi-Árido (UFERSA), em delineamento de blocos casualizados completos e quatro repetições. Os tratamentos foram constituídos pelos genótipos de cebola CNPH 6415, CNPH 6047, CNPH 6244, CNPH 6400 Chata, CNPH 6400 Redonda, CPACT 1, CPACT 2, CPACT 3, Granex 429, Belém IPA 9, BRS Cascata, Crioula Alto Vale, Bola Precoce, Primavera, Régia, Valeouro IPA-11, Brisa e Alfa São Francisco. As características avaliadas foram teor de sólidos solúveis totais, acidez total titulável, teor de vitamina C e teor de ácido pirúvico (pungência). Foram observadas diferenças significativas entre os genótipos para todas as características avaliadas. Os genótipos apresentaram uma variação significativa para todas as características avaliadas, confirmando dessa forma que o fator genético é determinante na caracterização de cada material. O teor de sólidos solúveis totais variou de 6,67 a 11,63 (º Brix), vitamina C de 22,7 a 46,81 (mg ácido ascórbico/100 ml de suco) e a acidez total titulável de 0,19 a 0,45 (% de ácido pirúvico). Os genótipos apresentaram pungência intermediária com variação de 5,0 a 12,73 (µmol/g), sendo os menos pungentes Granex 429, CNPH 6047, Régia, Primavera e Belém IPA 9.

Clinical and epidemiological study of 27 poisonings caused by ingesting puffer fish (Tetrodontidae) in the states of Santa Catarina and Bahia, Brazil

Os baiacus ou peixes-bola podem ser venenosos devido à presença em seus tecidos corporais de Tetrodotoxina e/ou Saxitoxina, ambas potentes neurotoxinas. Os autores relatam 27 envenenamentos por ingestão da carne de baiacus. Os pacientes foram atendidos nos Centros de Toxicologia de Santa Catarina e da Bahia de 1984 a 2009. Os acidentes foram classificados em moderados (52%) e graves (33%), havendo dois óbitos. O diagnóstico precoce é fundamental no sentido de garantir suporte ventilatório aos pacientes.

Caracterização histológica de folhas de Mentha pulegium x spicata (Lamiaceae)

The glandular hairs of Mentha pulegium x spicata (Lamiaceae) were studied by light microscopy and scanning electron microscopy, Three morphologically distinct types of trichomes are described: two of them are glandulars (peltate and capitate) and one is non-glandular hair (tector). Capitate trichome is of Type I, and consists of a foot cell, a stalk and a unicellular head with elongated format and two lateral depressions, showing the thinnest cuticle. The peltate trichome consists of a foot cell, a stalk cell and a radial cluster of secretory cells, cover by cuticle. The tector trichomes can be simple and forked -format, both multicellular, in which there are ornamentations on cell cuticle. The leaf cross sections, analysed in light microscopy, showed mesophyll organized for unistratification palisade parenchyma and lacurary parenchyma with four to five cell stratum. It was observed the presence of cristal mass agglomerate in mesophyll cells and in epidermical cells.

Improving the affinity of tomato grafted on Solanum torvum using an intermediate rootstock

Most of the interspecific rootstocks (Lycopersicum esculentum × L. hirsutum) used in grafted Spanish tomato crops are resistant to Meloidogyne nematodes, but the 'Mi' resistance gene does not work well at high soil temperatures. Ralstonia solanacearum is a bacterial disease usual in tropical areas, but recently identified with low incidence in several European countries. This disease could be controlled by grafting tomato on Solanum torvum, which is also resistant to Meloidogyne. However, S. torvum and tomato have low grafting affinity, which could be improved using an intermediate rootstock. Some cultivars of eggplant have a relatively good affinity with tomato and complete affinity with S. torvum. In this study we compared two tomato cultivars (one resistant to Verticillium dalihae, Fusarium oxysporum v. lycopersici race 2 and Meloidogyne spp., and one non-resistant) grafted onto 'Beaufort' (Lycopersicum esculentum × L. hirsutum), 'Torvum Vigor' (Solanum torvum) and also with an intermediate grafting of eggplant ('Cristal') between tomato and S. torvum, with nongrafted plants as controls. This arrangement was carried out in two cropping cycles (winter-spring and summer-autumn). In both cycles, plants grafted onto S. torvum, both single or double grafted, yielded less than those grafted onto 'Beaufort' or nongrafted plants. In the spring cycle, no differences were found between single and double-grafted plants using S. torvum rootstocks, but in the autumn cycle double grafted plants had higher yields than the single grafted plants. The severity of nematode infections, in terms of reducing yields, and/or hypothetical infections of Ralstonia, will determine the utility of this technique in tomato production.

EFFECT OF DIFFERENT ROOTSTOCKS ON GROWTH, CHLOROPHYLL A FLUORESCENCE AND MINERAL COMPOSITION OF TWO GRAFTED SCIONS OF TOMATO

Two tomato scions (cvs. 'Raf' and 'Gorety') were grafted on three different rootstocks: S. torvum, 'Beaufort' (Lycopersicum esculentum × Lycopersicum hirsutum) and intermediate grafting of eggplant 'Cristal' between tomato and S. torvum (double graft). Plants were grown in Mediterranean greenhouse conditions. The response to grafting was measured through growth parameters, Fv/Fm and leaf macronutrients analysis, and it was compared with non-grafted plants. The scions grafted on S. torvum in simple and double graft showed lower fresh and dry weight of leaves, number of commercial fruits, plant height, Fv/Fm and decreased their capacity to absorb several nutrients resulting in a lower mineral concentration in scions leaves, as a result of a thickened graft union. On the other hand, both scions showed a good response when grafted on the rootstock 'Beaufort', with which growth parameters, yield and photosynthetic capacity were similar to non-grafted plants. © 2013 Copyright Taylor and Francis Group, LLC.

Classification of crucifer cultivars based on the life-history of diamondback moth (Plutella xylostella)

We compared different cultivars and hybrids of crucifers in relation to development and life-history of diamondback moth (Plutella xylostella) to classify the plants according to their resistance to the pest. The plants used were Manteiga da Geórgia kale, Bola de Neve cauliflower, Ramoso Piracicaba Precoce broccoli, Chato-de-quintal cabbage, and the hybrid cabbages Midori, TPC668, TPC308, and TPC681. We evaluated performance daily until the pupal stage. Pupae were assessed individually to determine the pupal weight, performance, and pupal period. We determined the sex ratio, fecundity, fertility, and longevity of the emerged adults and calculated their reproductive potential. Cabbage hybrids TPC668, TPC308, and TPC681 do not support the development and reproduction of the diamondback moth. These hybrids show a level of resistance that is similar to that found the commercially available hybrid Midori and cultivar Chato de Quintal, which are known to be resistant to the diamondback moth. This finding implies that the capitata (cabbage) cultivars are the most suitable for planting because they are more resistant to pest than the cultivar's moth, acephala (kale). © 2013 Copyright Taylor and Francis Group, LLC.
