생약재로 이용되고 있는 활나물은 항암효과가 밝혀져 그 이용이 기대되나 종자발아가 불량하여 재배가 어려운 식물이다. 따라서 GA3, 저온, KNO3, acetone처리가 활나물의 종자발아에 미치는 영향을 구명하여 앞으로의 재배연구의 기초자료를 얻고자 본 연구를 실시하였던 바 그 결과를 다음과 같다. 1. 활나물 종자의 발아율은 GA3 처리시에는 0.1 mM에 12시간 암상태에서, 저온처리시에는 3℃에서 1주간 처리하는것에서 가장 높았다. 2. 발아율은 KNO3 처리시에는 400 mM에 6시간, acetone 처리시에는 200 mM에 6시간 처리하는 것에서 가장 높았으며, 이들 처리결과가 GA3 또는 저온처리의 최적결과보다 양호하였다. 3. 포장출현율은 200 mM의 acetone 용액에 6시간 처리하는 것보다 400 mM의 KNO3에 6시간 처리하는 것에서 높은 것으로 조사되어 활나물 종자처리는 KNO3를 이용하여 암상태에서 처리하는 것이 바람직한 처리방법으로 평가되었다.
Crotalaria sessiflora is one of a few medicinal herbs among the legumes used as antitumor herb medicine but has lower seed germination and afterward seedling emergence. This study was carried out to elucidate the effects of cold stratification as presown treatment as well as GA3, KNO3 and acetone on its seed germination and seedling emergence. Cold stratification, GA3, KNO3 and acetone treatments were performed with different concentrations and period levels. Cold treatment was done under 14 hour red light illumination a day or darkness and the two others under darkness. On the basis of the best germination rate of each treatment, GA3 and cold stratification treatments showed the highest germination rates at 0.1 mM but 12 hours and 2 week periods under darkness, respectively. KNO3 and acetone treatments came out at 400 mM and 200 mM lasted for, respectively. The best germination rates from KNO3 and acetone were comparatively higher than those from the former GA3 and cold treatments. In evaluation of seedling emergence using the last two treatments, KNO3 treated seeds were better performed than acetone treated seeds showed somewhat higher germination rate, implying that presown seed treatments must be evaluated by the combination with indoor and field tests.
