Seed dispersal seed germination and seedling establishment in natural forests of silver fir abies pindrow and spruce picea smithiana 1. seed dispersal pattern



Seed dispersal seed germination and seedling establishment in natural forests of silver fir abies pindrow and spruce picea smithiana 1. seed dispersal pattern



Indian Forester 110(6): 529-539



Studies on seed dispersal were carried out in a mixed forest silver fir and spruce in Kotgargh Forest Division, Himachal Pradesh [India]. The number of seeds dispersed per square meter of forest floor area in case of silver fir and spruce varied from 51.9-528.6 and 9.2-65.8, respectively. The peak dispersal period for silver fir was from Nov. 13-24, when 85.84% of the total seed (by weight) was dispersed while the same for spruce was from Oct. 27 to Dec. 1 during which period 84.50% of the total seed (by weight) was dispersed. In case of silver fir the seed dispersed after Oct. 13 to Nov. 10 were .apprx. 5 g heavier than dispersed in other weeks and there was no such difference discernible in case of spruce.
