Abstract
Five seed sources of A. pindrow, collected from Garhwal Himalaya were studied for cone and seed characteristics and germination behaviour. Three different sizes of cones (large, medium and small) were observed in all the seed sources. The dimensions of large (14.25 x 4.76-16.04 x 4.56 cm), medium (11.45 x 4.17-12.28 x 4.43 cm) and small (9.01 x 4.05-9.68 x 4.08 cm) sized cones in 5 different seed sources of A. pindrow oscillated greatly. The maximum cone moisture content also varied significantly (45.22-55.37%) in the cones. The largest seed observed was 1.17 cm long x 0.87 cm wide and the smallest was 0.56 cm long x 0.19 cm wide. The seed mass was heaviest with wings (7,35 gm/100 seeds) and without wings (6.84 gm/100 seeds) in Tapovan seed source on fresh weight basis. The highest (56.0%) germination was observed in Dudhatoli seed source at 10oC and the lowest (10.0%) at 25oC in Tapovan seed source. Dudhatoli seed source was recorded to be the best seed source, which may give highest productivity if tried on other sites. This seed source may be used to establish Seedling Seed Orchards due to additive genetic gain and higher germination percentage of seeds.
