Abstract
Prunus cerasoides is indigenous multipurpose tree species of the Himalayan regions and is also used for religious purpose, edible fruit, seed and gum as well as different medical applications, lumber, dyestuff and tannins. The present investigation was carried out to estimation the variability in fruit, seed characteristics and seed germination of P. cerasoides from different sources of Garhwal regions of Uttarakhand. The experiment consisted of six seed sources and fifteen different pre-sowing treatments, the data regarding on fruit and seed morphology were analyzed for Randomized Block Design, while seed germination and seedling growth data were analyzed for Completely Randomized Design. Among the seed sources, Silyara, Kuteti and Sadargaun seed source were showed superiority with respect to fruit and seed morphology. For seed germination and growth attributes, the highest (72.86%) germination percent was recorded in Silyara seed source followed by Sadargaun (69.00%), Kuteti (66.66%), Develgaun (64.4%), Chaurangikhal (63.06%) and Ranichauri (55.00%). In pre-sowing treatments, Gibberellic acid and hot water for 100⁰C at 24 hours was showed maximum germination percent and total seedling growth as compared to other treatments. The maximum heritability, genetic advance and genetic gain were found in seed length and seed weight. These two characters might be considered for the improvement in P. cerasoides. Correlation coefficient among various geographical, edaphic and climatic factors of seed sources with different fruit and seed characteristics were showed significant interrelationship between fruit and seed parameters. The overall study indicated that Silyara, Kuteti and Sadargaun seed sources are superior with respect to fruit, seed, seedling morphology and germination attributes as compared to Develgaun, Chaurangikhal and Ranichauri seed sources. The application of treatment GA3 solution and hot water for 100⁰C at 24 hours are better for seed germination and seedling growth in case of P. cerasoides.
