Abstract
O maracujazeiro está entre as principais fruteiras cultivadas no País, sendo a propagação por sementes o método predominante na produção de mudas. Para obtenção de sementes de boa qualidade, um dos aspectos que devem ser considerados é o momento de sua coleta, que pode ser determinada pelo estádio de desenvolvimento do fruto. O objetivo deste trabalho foi verificar a influência do estádio de maturação dos frutos e de armazenamento pós-colheita sobre a germinação e o desenvolvimento inicial de maracujazeiro-amarelo (Passiflora edulis f. flavicarpa). O trabalho foi realizado na Universidade Federal de Viçosa (MG). As sementes utilizadas foram extraídas de frutos em três estádios de maturação (estádio 1 - verde começando a alterar sua coloração para amarela; estádio 2 - fruto com 5 até 50% de coloração amarela, e estádio 3 - fruto com mais de 50% de coloração amarela) e quatro períodos de armazenamento pós-colheita (0; 3; 6 e 9 dias) à temperatura ambiente. Posteriormente, as sementes foram semeadas em caixas plásticas com areia fina lavada. Foi utilizado o delineamento experimental em blocos casualizados, num fatorial 3 x 4 (estádio de maturação x período de armazenamento), com quatro repetições, considerando como unidade experimental cada 50 sementes. Conclui-se que a extração de sementes de maracujazeiro-amarelo deve ser realizada de frutos em estádio de maturação 2 e 3. Já o desenvolvimento das mudas de maracujazeiro-amarelo é melhor observado mantendo os frutos durante 3 a 6 dias em armazenamento antes da extração de suas sementes.
The passion fruit is among the main fruit crops cultivated in Brazil. The propagation is predominantly by seeds. Seeds with good quality should be collected at adequate development stage, which can be established according to the fruit maturity stage. The aim of this work was to verify the influence of the fruit maturity stage and the post-harvest storage in the germination and initial development of the seedlings of yellow passion fruit (Passiflora edulis f. flavicarpa). The work was carried out in the Federal University of Viçosa (MG), Brazil. The seeds used were extracted of fruits in three fruit maturity stages (stage 1 - green beginning to alter its fruit epidermis coloration to yellow; stage 2 - fruit with 5 until 50% yellow epidermis coloration and stage 3 - fruit with more than 50% yellow epidermis coloration), and four post-harvest storage periods (0, 3, 6 and 9 days) at room temperature. After, the seeds were sowed in plastic boxes with fine washed sand. The experiment was designed in completely randomized blocks, in a factorial 3 x 4 (maturity stage x post-harvest storage period), with four replications, where each plot was constituted by 50 seeds. It was concluded that, the yellow passion fruit seeds should be extracted at the fruit maturity stages 2 or 3. For the development process of the yellow passion fruit seedlings it was recommended to store the fruits during 3 to 6 days before the seeds extraction.
