Abstract:
An investigation was carried out during April-May, 2019 with an objective to determine the effective pre-sowing treatment for seed germination of Morus laevigata Wall., an economically important valuable tree species belonging to the family, Moraceae, known for its quality timber especially for furniture and indoor structures. The experiment was laid out in a completely randomized design in laboratory conditions subjected to 17 pre-treatments with four replications each. The depulped seeds pre-treated with gibberellic acid (GA₃) application of 250 ppm, 500 ppm and 1000 ppm for 12 h resulted significant higher germination in T₈ (60.25%), T₉ (74.25%) and T₁₀ (87.50%) respectively, which accelerated with increase in concentration of gibberellin amongst the treatments. In conclusion, the application of GA₃ was effective in increasing seed germination percentage and germination energy for production planting stock, raising plantations and reforestation, subsequently.
