The present study describes seed viability, germination and storage behaviour studies of Eremostachys superba seeds under controlled condition. Eremostachys superba is an endangered medicinal and ornamental herb of North-West Himalaya. Fresh seeds exhibited 98% seed viability and a gradual decrease in seeds stored for different durations at room temperature (RT) and 0-4°C in refrigerator. Maximum germination percentage was observed in seeds stored at 0-4°C for 6-months (35.15%) as compared to the freshly collected seeds (5.7%). Seed germination percentage was enhanced by presoaking the seeds in different concentrations of gibberellic acid. Presoaking of seeds in 400ppm of GA3 was found most effective and 79.32% and 29.43% germination was reported in the seeds soaked in 400ppm GA3 and stored for 6-months at 0-4°C while 29% germination was seen in freshly collected seeds stored at the same temperature and duration. Seeds stored for 6 months at 0-4°C, after presoaking for 24 hours in 400ppm GA3 and sowing in the month of August were found to be most conducive for propagation.References
