저장 및 발아 온도조건에 따른 황기 종자의 발아 특성

초록

This study was investigated to evaluate germination rate of Astragalus membranaceus B. in Korea as affected by storage temperature, germination temperature and storage period of seed. The highest germination rate was obtained from condition of 25℃ in germination temperature. Seeds were stored at −20℃ and 5℃ for 8 weeks has showed higher germination rate than one at room temperatures. The germination rates showed significantly difference by harvested year of 2010, 2011 and 2012. The seed of A. membranaceus in harvested year of 2011 and 2012 had germinated well. On the other hand, seeds in harvested year of 2010 were not nearly germinated. Consequently, the longer storage period after seed harvest lower germination rate and seed vigor as well.
