abstract
An experiment was conducted during the year 2015-16 at Biotechnology-cum- tissue culture centre, OUAT, Bhubaneswar, India to study the effect of GA₃ pre treatment ((i.e. 700, 710, 720, 730, 740, 750, 760, 770,780,790,800 ppm) respectively and a control (without any treatment) on seed germination and seedling growth in Cassia fistula L. seeds. Seeds treated with GA₃ at 760 ppm significantly enhanced the germination percentage (56.66%), mean daily germination (3.77), peak value (12.75), germination value (49.60), plant height (30.00 cm), number of leaves (15.66), root length (24.66 cm). Fresh biomass (1.32 g) and dry biomass (0.52 g) at 45 DAS. Hence it may be concluded that seeds pre-treated with GA₃ at 760 ppm play an important for obtaining better quality seedlings of Cassia fistula L.
