Abstract

ABSTRACT This paper describes results of studies on seed storage and germination of Himalayan blue pine. The effects of seed storage and germination temperatures and stratification, insecticidal and fungicidal treatments on germination of blue pine seed were determined for different seed sources of this species in these studies. It was observed that the viability of blue pine seed is significantly reduced within short period if it is stored at high temperature. Seed stored in dry cold or stratified condition retains its viability and maximum terminations per cant as well as speed of germination are obtained if the seed is stratified for 120 days. Insecticidal treatment of seed in storage adversely affects its germination. Large differences were also noticed between different seed sources of blue pine in respect of various germination characteristics.
