INDUCTION OF SEED GERMINATION IN THE RET MEDICINAL PLANT, JYOTHISHMATHI (CELASTRUS PANICULATUS WILLD.)
Celastrus paniculatus, one among the RET medicinal plants, shows poor germination under natural conditions. To induct germination, experiments were carried out by using different concentrations of ethyl alcohol at different time intervals (100%, 70%, 50% for 1 minute, 30 minutes, 60 minutes and 120 minutes), hot water with different temperatures (100, 90, 80, 70 and 50 degree Celsius for 1 minute, 2 minutes and 3 minutes), different concentrations of sulphuric acid (100%, 70%, and 50% for 10 seconds, 30 seconds and 1 minutes), rolled towel method and mechanical scarification. Maximum germination rate of 70% was obtained when the seeds were treated with 70% ethyl alcohol for 120 minutes. 50 % germination rate was obtained in the case of seeds treated with rolled towel technique. Treatment with hot water of 70°C for 3 minutes and 2 minutes also resulted in an increased rate of germination than the control. However, sulphuric acid treatment and mechanical scarification has not recorded a promising result in the present study.
