Abstract
The period of seed viability for the majority of passiflora species is unknown and the prolonged period of natural or induced dormancy make seed germination slow and unevenness. Hence, an experiment was conducted to study the influence of seed storage period and pre-germination treatments on viability and vigour of passion fruit seeds . The study revealed that seeds sown after 15 days of storage significantly recorded higher seed quality parameters like shoot length (11.58 cm), root length (4.92 cm), fresh weight of the seedling (78.79 mg), dry weight of the seedling (8.27 mg), seedling vigour index-I (901) and seedling vigour index-II (458.96) which reduced with different storage period. Irrespective of seed storage period, seeds treated with thiourea 1 per cent for 10 minutes resulted in more germination percentage and seedling quality parameters followed by seeds treated with GA3 250 ppm for 10 minutes.
