Resumo
O Brasil é o quarto produtor mundial de caqui e o Estado de São Paulo responde por aproximadamente 58% da produção nacional. Observa-se uma tendência mundial em exigências quanto à qualidade e segurança do alimento, visto a divulgação de surtos de DTAs (doenças transmitidas por alimentos). Os patógenos responsáveis pelas DTAs podem ser introduzidos nas frutas em qualquer etapa da cadeia produtiva. Deste modo, elaborou-se este trabalho com o objetivo de realizar um diagnóstico das práticas empregadas em pós-colheita do caqui 'Rama Forte' e 'Fuyu', propor medidas de Boas Práticas Agrícolas (BPA) e elaborar um modelo do plano de Análise de Perigos e Pontos Críticos de Controle (APPCC), visando a qualidade e a segurança do alimento para o consumidor. Para diagnosticar os principais perigos e pontos de contaminação no manuseio do caqui, foram aplicados questionários de práticas de campo e pós-colheita em 11 galpões de embalagem de caqui 'Rama Forte' e 'Fuyu', nas principais regiões produtoras do Estado de São Paulo. Amostras para análises microbiológicas foram coletadas em diferentes etapas, da colheita até o varejo, sendo realizadas contagens de bolores e leveduras, coliformes totais e termotolerantes, bem como, pesquisa de Salmonella spp. e Listeria monocytogenes com o sistema BAX®. Os resultados dos questionários indicaram que, o caqui não é submetido a tratamentos fitossanitários pós-colheita; não há aplicação de Boas Práticas Agrícolas e os manipuladores dos diferentes segmentos da cadeia produtiva não recebem treinamento em práticas de higiene pessoal e segurança do alimento. Outros pontos relevantes que comprometem a qualidade do produto e geram perdas significativas são o uso inadequado de embalagens e transporte, o processo de destanização e máquinas de classificação...
It was evaluated the yield, accumulation and exportation of nutrients by sweet pepper plants grafted and non grafted, under protected cultivation. The research was carried out from August 2003 to May 2004, at the Technical School Augusto Tortolero Araújo, part of Paula Souza State Center of Technological Education, in Paraguaçu Paulista, SP, in Brazil. The rootstocks used - AF 2638 and AF 2640, are resistant to Phytophthora capsici Leonian and Meloidogyne incognita race 2. The treatments were constituted of non grafted hybrids 'Rúbia R' and 'Margarita'; grafted on two evaluated rootstocks and grafted on themselves. The experimental design was of completely randomized blocks with eight treatments, four replications and fifteen plants per plot. Five plants were sent for chemical analysis. Evaluations of the total plants height, first fork height, early blossom, length and average number of internodes, total yield and fruits characteristics of 12 harvests, fresh and dry matter of leaves, stems and fruits, were carried out. The samples for the chemical analysis were taken at the 35th, 83th, 135th, 173th and 213th days after transplantation, with the objective of determining the accumulation and exportation of the nutrients. The results proved that the grafted and non grafted plants had average yield, with the average of 132 and 153 t ha-1 for the grafted combinations of 'Rúbia R' and non grafted plants of 'Rúbia R' respectively and 144 and 132 t ha-1 for the grafted combinations of 'Margarita' and non grafted plants of 'Margarita' respectively. The accumulation of the nutrients was equivalent for grafted combinations and non grafted plants, and nutrients in decreasing order of accumulation were: K>N>Ca>Mg>P>S. It was evidenced that grafting sweet pepper plants neither its agronomic performance, nor interfered on the uptake of nutrients' absorption.
