          Abstract

          Este estudo teve por objetivo avaliar o uso de diferentes invólucros nos frutos de atemoieira e pinheira na qualidade físico-química dos frutos e na incidência da broca-dos-frutos, Cerconota anonella. Os experimentos foram instalados em dois pomares comerciais: um de atemoieira no município de Matias Cardoso e outro de pinheira no município de Verdelândia, Norte de Minas Gerais. Os tratamentos para a atemoieira consistiram em: 1) Testemunha (sem ensacamento); 2) Saco plástico leitoso; 3) Saco de TNT (tecido-não-tecido) branco sem fundo e 4) Saco de TNT branco com fundo. Para a pinheira foi modificado apenas o tratamento 2 para saco de papel pardo. Avaliaram-se número de dias da polinização à colheita, número de dias da colheita ao amadurecimento, ocorrência de injúrias e brocas e características físico-químicas dos frutos. Observam-se maior número de dias entre a colheita e o amadurecimento e mais firmeza nos frutos de pinheira não-ensacados. O uso do plástico leitoso controlou a broca em frutos de atemoieira. As características físico-químicas: massa, comprimento, diâmetro dos frutos e teor de sólidos solúveis totais da polpa não foram influenciados pelo uso dos invólucros.

          Translated abstract

          This study was conducted to evaluate the effect from using different involucres for fruits of the atemoya and sweetsop upon either physiochemical quality of the fruits and incidence of the fruit borer Cerconota anonella. The experiments were set up in two commercial orchards: one with atemoya at Matias Cardoso county and the other one with sweetsop at Verdelândia on northern Minas Gerais state. The treatments for atemoya consisted of: 1) Control (without bagging); 2) Milky plastic bag; 3) White, bottomless, tissue-non-tissue (TNT) bag; and (4) With bottom TNT bag. For the sweetsop, only treatment 2 was modified to brown paper bag. The following evaluation were performed: the number of days from pollination to harvest, number of days from harvest to ripening, occurrence of injuries and borers, and the physiochemical characteristics of the fruits. The no-bagged sweetsop fruits showed higher number of days between the harvest and ripening and higher firmness. The use of the milky plastic controlled the borer in atemoya fruits. The following physiochemical characteristics were not affected by the use of those involucres: weight, length, fruit diameters, and the content of the total soluble solids in the pulp.
