Seed Germiability, viability and longevity of Rhododendron arboreum var. arboreum Sm.
Author(s): Vinod Kumar and Dr. Rajesh Sharma
Abstract: The present study has been undertaken with the objective to assess the germiability, viability and longevity of R. arboreum seeds at laboratory conditions as these factors are very important to promote the process of natural regeneration of species in wild which ultimately responsible for the better survival and existence of species. The seeds for experiment were collected from Craignaino forest in Mashobara Range of Shimla forest division. Seed parameters like Germination per cent, germination energy and germination value were calculated to test the germiability from the freshly collected seeds continuously for the period of six years. Seed viability was assessed through germination method and TTZ (Tetrazolium salt) method. A storage trial was designed by using polythene bags and cloth bags as a medium of storage of seeds, to check the longevity of the seeds under three different temperature gradients (deep freezer, Multi cooling chamber and normal room temperature). The results are diverse, having common observation with higher viability in freshly collected seeds as compared to the previous years. The overall Results showed tendency of decline in germiability as well as loss in viability over a period of time. The deep freeze (-20°C) is the best suitable temperature gradient for the storage of R. arboreum seeds as the maximum viability of the seeds has been observed in this medium with the 50% decline in viability in the period of 3 years.
