가시오갈피 개갑종자의 저온처리에 의한 발아 묘목의 생육특성

초록

This experiment was carried out to study the optimal chilling period for breaking the physiological dormancy of dehisced E. senticosus seeds and to investigate the critical seeding date in Kangwondo. Storage at 5℃ for 85 days was most effective in breaking dormancy of dehisced seeds, but didn't germinated synchronously. Only 28.1% of undehisced seeds germinated after 125 days of low temperature storage. For improving seedling survival rate in the field, 50% shading was more effective than 30% shading. Delayed seeding date resulted in decreased seedling fresh weight, dry weight, leaf area and root length, but seeding date has no significant affecte on stem length.
