In the present study, yellow light significantly enhanced fresh weight and leaf area as compared to all other light sources (Figs. 2B, 3). The yellow light treatment was found favorable for the survival of gamma irradiated shoots with maximum survival percentage (100%) at all the radiation doses (Table 2). Yellow light treatment resulted in significant increase in fresh weight (Table 5) and shoot length to (Table 3) at 15, 30 and 45 Gy. Higher doses 60, 80 and 100 Gy showed decrease in fresh weight (Table 5) and shoot length (Table 3). Similar trend was observed in case of exposure of cultures to red light.
