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.
