Effect of Seed Presowing Treatments on Germination Parameters in Albizia Procera

Abstract

Albizia procera is an important tree species and it belongs to the Fabaceae family. An experiment was conducted to determine the most effective pre-sowing treatments for maximizing germination. Ten pre-sowing treatments were tested, with data collected on daily basis to calculate the germination percentage (G%), germination rate index (GRI), mean daily germination (MDG), peak value (PV), germination value (GV), and mean germination time (MGT). Significant differences were observed between the seed pretreatments and control for all parameters. The highest germination percentage (90.00%), GRI (27.12%), MDG (2.81), PV (10.00), and GV (28.13) were achieved in seeds pretreated with 50 ppm GA3 for 12 h (T9). Seeds treated with hot water at 70 °C for 5 min followed by soaking in tap water for 24 h also showed improved results. This study helps to identify the most effective pre-sowing treatments to improve germination rates and seedling establishment of A. procera, thereby enhancing the success of large-scale plantations in agroforestry and social forestry initiatives.
