Abstract:
Recalcitrant seeds are desicative and chilling sensitive and are viable for a very short period. Seeds of Jackfruit (Artocarpus heterophyllus Lam.) being recalcitrant in nature pose storage problem. Hence, an experiment was conducted during 2020-21 to study the different growing media and pre-germination treatments on viability, vigour and growth of jackfruit seeds. The two factorial experiment was conducted on the different growing media [Soil + FYM (3:1)-control, Soil + Cocopeat (3:1), Soil + Vermicompost (3:1) and Soil + Vermicompost + Cocopeat (2:1:1)] on seed germination and different growth regulators and chemicals viz., water soaking (control), GA₃ @ 250 ppm for 12 hour, KNO₃ @ 1 per cent for 3 hour, and Thiourea @ 1 per cent for 1 hour. Results revealed that Soil + Vermicompost + Cocopeat (2:1:1) and GA₃ @ 250 ppm for 12 hours were exhibited maximum germination (69.54% and 91.26%), seedling height (32.75 cm and 43.47 cm), number of leaves (4.54 and 6.32) seedling vigour index-I (4905 and 6473), maximum fresh (14.26 g and 18.35 g) and dry weights (3.54 g and 4.45 g) of seedlings.
