The aims of this study was to classify Iris ehrysographes dormancy type and investigate the optimum treatment for seeds germination through examining the effects of various incubation temperatures, light conditions, scarification, stratification and soil substratum. Seed viability of/. chrysographes was 74% and seeds imbibed water very fast. No seeds germinated on stratification, soil substratum, constant or alternating temperatures, light and darkness treatments. Seeds germination of different mechanical restriction treatments had significant differences. The results indicated that： （1） removal of seed coat was the most effective treatment for/. chrysographes germination; （2） physiological dormancy phenomenon was found in this species.展开更多
