Effect of Pre-Sowing Treatments on Seed Germination and Establishment of Bauhinia rufescens
The aim of the present study was to investigate the effect of various pre-sowing treatments on the germination of Bauhinia rufescens seeds. The pre-sowing treatments were made up of boiling seeds in water for up to 15 min and soaking seeds in water at room temperature for a number of days. Data collected was used to calculate cumulative germination percentage, germination value, speed of germination, mean daily germination and coefficient of velocity and was analyzed using analysis of variance at 5%. Treatment 1 (<10 sec boiling) produced the highest cumulative germination percentage of 77. Soaking seeds in water at room temperature for any number of days (T3, T4, T7, T11, T14) did not have any significant effect on germination, neither did boiling seeds for 15 min (T2) and the control (T15). Apart from T1, all the other treatments had a cumulative germination percentage of less than 20 at the end of the experiment. Boiling of Bauhinia rufescens seeds in water for less than 10 sec (T1) proved to be the most effective pre-sowing treatment to enhance germination under field conditions. Soaking of seeds in water for any number of days could not improve germination.
