Abstract

Therefore, seeds collected from 1700 m a.b.l in Kojor, Mazandaran province were putted under a variation of STRATIFICATION treatment in wet sand at different temperature and periods such as, warm STRATIFICATION at 20oC for 1 months, cold STRATIFICATION at 2-4oC for 2,3,4 months and warm-cold STRATIFICATION for 1,2,3 months cold after 1 months warm STRATIFICATION. Results showed that the highest germination (80%) at the rate of 1.25 seeds/day took place in cold STRATIFICATION for 4 months and the lowest (17%) at the rate of 0.32 seeds/day in warm-cold for 1-1 months res. Comparing of results between cold and warm-cold STRATIFICATION in the cases of percentage and rate of germination state that cold STRATIFICATION for 2 months stimulates germination about 27% at the rate of 0.56 seeds/day. However in warm-cold STRATIFICATION for 1-2 months res. Germination was about 60% at the rate of 0.88 seeds/day. Cold STRATIFICATION for 3 months stimulated germination about 73% at the rate of 1.17 seeds/day where these characteristics in warm-cold STRATIFICATION for 1-3 months res. were about 72% at the rate of 1 seeds/day. On this basis, it can be said that seeds of Persian Hogweed has Morphophysiological dormancy and the best way for braking dormancy and stimulation of SEED GERMINATION is STRATIFICATION in cold-wet sand for 4 months.
