Abstract:
The aim of this paper was to find the effect of pre-sowing treatments on the germination parameters of Michelia champaca L. which has low germination status in nature. The experiment was conducted with fourteen treatments in four replications carried out in the laboratory and nursery bed to improve germination on fresh seeds after removal of fleshy aril. Significant differences in germination were observed with maximum of 43.8% germination when seeds were soaked in gibberellin acid (500 ppm) for 24 hr. and subsequently soaked in 4% hydrogen peroxide for 24 hr. (T₁₄) followed by T₆ (41%) soaked in 4% hydrogen peroxide for 12 hr. were the most effective methods to enhance germination rates. In contrast, the germination percentage of seeds of treatments T₈ (1.30%) and T₉ (1.50%) was lower than control T₁ (2.50%) may be due to detrimental effect of nitric acid, the results of the present study may be useful for the production of planting stock in nurseries for plantation and commercial purposes.
