ABSTRACT
To study the effects of accelerated aging on seeds of
Chir pine (Pinus roxburghii Sarg.) three seeds lots from
different localities were subjected to AA at 41°C for 24, 36, 48, 60, 72, 96,and 120 hours. The AA time affected
the three seed germination and PV significantly and all
the three seed lots were found significantly different
from each other. Moisture content of seeds continuously
increased with increasing AA time Lot A had the highest
vigor followed by lot B, while lot C was the lowest in
vigor.
