Abstract
Seeds of kail collected from 10 localities in the western Himalaya were germinated at 4 temperatures viz 20°, 28°, 34° and 40°C after storage in dry cold conditions in freezer. The seed lots representing different localities differed in the capacity and rate of germination. At lower temperature of incubation (20°C) most of the seed lots exhibited varying degree of dormancy. This dormancy could be revoked by chilling imbibed seeds for 2 weeks at 3–5°C. At higher temperatures of incubation the seed lots did not exhibit dormancy, although the optimum conditions for germination were provided by a combination of prechilling and higher temperatures of incubation (28° and 34°C). Treatments such as prolonging the stratification period up to 38 days, soaking in GA 100 mg/litre, with or without prechilling, and in 1% H2O2, did not have any significant effect on germination. The study revealed seed source variation in the degree of dormancy at low temperature of incubation.
