The experiment was laid out in Randomized Block Design with eleven seed priming treatments viz., GA3 (250, 500, 750 ppm), Thiourea (2500, 5000, 7500 ppm), KNO3 (2500, 5000, 7500 ppm), hydro-priming and control (no priming) replicated thrice. Among all the treatments GA3 @ 500 ppm performed significantly better than all other treatments over control in terms of germination i.e. seed germination (64.26 %), days taken to germination (38.40) and growth parameters i.e. seedling height (29.10 cm), seedling diameter (6.27 mm), number of leaves per seedling (17.07), leaf area (86.04 cm2), leaf chlorophyll content (2.05 mg/g), fresh weight of shoots (16.32 g), dry weight of shoots (8.57 g), total root length (1.45 m), fresh weight of roots (11.97 g), dry weight of roots (6.24 g), biomass of seedlings (14.81 g), seedling vigour indexI (2547.88), seedling vigour index-II (951.91), survival rate (93.84 %) and number of graftable seedlings (96.99 %).EnglishThesis
