Abstract:
The germination of passion fruit seeds is less and uneven. Hence, an experiment was conducted during 2020-2021 to study the effect of pre-germination treatments on germination, growth and vigour of passion fruit. The study revealed significant differences among the treatments. Maximum germination percentage (59.48%) was observed in seeds treated with thiourea @ 1 per cent. Maximum seedling height 8.66 cm, 24.71 cm and 26.54 cm in thiourea treatment and number of leaves 3.47, 7.73 and 9.47 were observed in seeds treated with GA3 250 ppm at 30, 60 and 90 days respectively. Vigour index-I (1571) and Vigour index-II (82.38), maximum fresh and dry weights of shoot were 6.50g and 1.38g respectively in thiourea treated seeds. The use of pre-germination treatments is therefore recommended as an approach for germination of passion fruits.
