Abstract

An experiment entitled “To study the impact of seed storage period and growth regulators on physiological parameters of Jackfruit (Artocarpus heterophyllus Lam.) seedling” was conducted in a 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 days 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 for 24 hrs (G) viz., G1- GA3 ‘at’ 100 mg 1-1, G2- GA3 ‘at’ 150 mg 1-1, G3- NAA ‘at’ 25 mg 1-1, G4- NAA ‘at’ 50 mg 1-1 and G5- Control. The experiment was conducted in Completely Randomized Design (Factorial) with 15 treatment combinations and repeated thrice. Sowing of fresh extracted seeds of jackfruit recorded at 90 DAS maximum leaf area (43.38 cm2), root: shoot ratio (0.22), vigour index-I (41.60) and vigour index-II (3.17). While, Soaking seed in GA3 ‘at’ 100 mg l-1 for 24 hrs recorded at 90 DAS maximum leaf area                  (52.34 cm2), root: shoot ratio (0.22), vigour index-I (38.08) and vigour index-II (3.13). Treatment combination sowing of fresh extracted seeds and soaking seeds in GA3 ‘at’ 100 mg l-1 for 24 hrs recorded at 90 DAS maximum leaf area (59.87 cm2) vigour index-I (56.03) and vigour index-II (5.37).

Keywords: Jackfruit, seed storage period, growth regulators, leaf area, vigour index
