The effect of invigoration treatments of seed pelleting on various germination parameters of seeds of two bamboo species i.e. Dendrocalamus hamiltonii and Bambusa bambos have been studied for 18 months period. Our studies were directed to investigate the effectiveness of invigoration treatments on vigor and viability of seeds. During storage, treated seeds (Pre-storage seeds) were stored at controlled temperature and humidity (in desiccators at 4 °Celsius). Pelleting of seeds was done with Calcium oxychloride, Calcium carbonate and turmeric powder in both the species. Statistically, it was observed that pelleting with turmeric powder resulted in maximum germination percentage of 36.4 % and 24.9% over control at 12 and 18 months, respectively, which was zero in Dendrocalamus hamiltonii. In case of Bambusa bambos all the pelleting materials were effective but Calcium oxychloride was most effective in maintaining germination with maximum germination of 31.2% and 15.8% over control at 12 and 18 months, respectively which was zero after 12 months. Moreover, 10% concentration of turmeric powder in Dendrocalamus hamiltonii and 10% concentration of Calcium oxychloride in Bambusa bambos was statistically significant at 5% level in all the treatments for maintaining germination.
