Publication Date : 01/08/2019
Field experiment was conducted to determine the most suitable pre sowing treatments for seed germination and seedling growth of walnut. The study shows that germination and seedling growth of walnut was improved with combine application of all pre sowing treatments. Nut cracking + gibberellic acid @ 500 ppm + stratification for 60 days showed highest germination percentage where as early germination was observed under the treatment combination of nut cracking + gibberellic acid @ 1000 ppm + stratification for 60 days. Highest shoot height, shoot diameter, number of leaves per plant, root length, root area, shoot fresh weight, root fresh weight, total fresh weight and survival percentage were recorded in treatment with hot water + gibberellic acid @ 500 ppm + stratification for 60 days. Therefore, the results of present experiment indicate that it is the combination of various pre sowing treatments which was found effective in improving the germination as well as growth of walnut seedlings as compared to the control.
