The leaf total chlorophyll content of all the gamma irradiated and monochromatic light treated shoot cultures was determined except for the shoots irradiated at higher doses (beyond 45 Gy) as these shoot cultures failed to survive and/or produce leaves. The shoots irradiated at 15 and 30 Gy followed by white and blue light treatment exhibited higher chlorophyll content than respective control (non-irradiated) shoots (Table 6). Similar trend was also noticed for 15 and 30 Gy irradiated cultures under yellow and red light (Figs. 1 and 2). In case of yellow and red light treatments for shoot cultures exposed to higher doses (45 Gy–100 Gy), there was no definite trend for changes seen in chlorophyll content. The gamma irradiated cultures under white light showed higher chlorophyll content followed by yellow light treatment (Table 6). Plantlets transplanted into small pots containing coco-peat (Fig. 4) were acclimatized with good survival (100%).
