Abstract:

An experiment was conducted in 2017 to study the seed quality of pumpkin (Cucurbita pepo L.) variety Punjab Samrat as affected by stage of fruit harvest and post harvest storage duration and to see their effect on longevity of the seed. Fruits were harvested 25, 35 and 45 days after anthesis (DAA) which were stored for 0, 10, 20 and 30 days after each date of harvesting (DAH). These seeds were stored in cloth bags under ambient conditions for 9 months. The germination, speed of germination, seedling length, dry weight and vigour indices were better in fruits harvested at 45 DAA. Similarly seed quality was better when pre-storage duration were 30 days. The longevity of the seed also remained high in the mature seeds. The interaction effects revealed that germination percentage, speed of germination, seedling length, dry weight and vigour indices were better when fruits were harvested 45 DAA and retained for at least 10 days in fruits before harvest. Therefore to get good quality seed and to retain its viability for longer period should be harvested 45 DAA and pre-stored for at least 10 days before its extraction.
