Abstract:
An experiment entitled “Effect of seed storage period and growth regulators on seed germination, growth and survival of jackfruit seedling” was conducted in green shade net house at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand during the year kharif- 2019. The treatment comprised three levels of seed storage period (S) viz., S1- 0 day after extraction of seed, S2- 5 days after extraction of seed and S3- 10 days after extraction of seed and five seed soaking treatments of growth regulators GA3 24 hrs (G) viz., G1- GA3 @ 100 mg l-1, G2- GA3 @ 150 mg l-1, G3- NAA @ 25 mg l-1, G4- NAA @ 50 mg l-1 and G5- Control. The experiment was carried out in Completely Randomized Design (Factorial) with fifteen treatment combinations and repeated thrice. Sowing of fresh extracted seeds of jackfruit recorded minimum number of days (14.89) taken for germination with maximum germination percentage (81.60) and at 90 DAS maximum height of seedling (37.78 cm), girth of seedling (4.32 mm), number of leaves per plant (6.88), length of seedling (50.99 cm), root length (13.21 cm), fresh weight of shoot (8.04 g), fresh weight of root (2.33 g), dry weight of shoot (3.19 g), dry weight of root (0.69 g), and survival percentage of seedling (69.60).Jackfruit seed soaked in GA3 @ 100 mg l-1 for 24 hrs recorded significantly, minimum number of days (15.58) taken for germination with maximum germination percentage (76.67) and at 90 DAS maximum height of seedling (37.57 cm), girth of seedling (4.07 mm), number of leaves per plant (6.97) length of seedling (49.67 cm), length of root (12.10 cm), fresh weight of shoot (8.13 g), fresh weight of root (2.25g), dry weight of shoot (3.35 g), dry weight of root (0.73 g) and survival percentage of seedling (68.18). Fresh extracted jackfruit seed soaked in GA3 @ 100 mg l-1 for 24 hrs recorded minimum number of days (12.34) taken for germination with maximum germination percentage (96.67) and at 90 DAS maximum height of seedling (43.30 cm), fresh weight of shoot (10.33 g), dry weight of shoot (4.59 g), dry weight of root (0.97 g) and survival percentage of seedling (84.24).
