새우난초, 금새우난초 및 이들 교잡종자(交雜種子)의 기내(機內) 무균발아(無菌發芽)에 적합(適合)한 기내(機內) 배양조건(培養條件)을 구명(究明)하기 위하여 수분후(受粉後) 일수(日數), 기본배지(基本培地), 초음파(超音波) 처리효과(處理效果) 실험(實驗)을 수행(遂行)하였다. 수분후(受粉後) 100일(日)된 새우란 종자(種子)를 MS배지에 파종(播種)하였을 때 발아율(發芽率)이 가장 양호(良好)하였으며 초음파(超音波) 처리시간별(處理時間別)로는 10분간(分間) 처리(處理)한 다음 파종(播種)하였을 때 발아소요일수(發芽所要日數)는 단축(短縮)되고 발아후(發芽後) 유묘(幼苗)의 생육(生育)도 양호(良好)한 경향(傾向)이었다.

The experiment was carried out to find the optimal condition for seed germination in vitro of Calanthe species. Seeds of Calanthe spp. after 90 days self pollination were well germinated in the MS medium. Germination condition of cross seeds between C. discolor and C. striata was much improved by pretreatment of micro sonic waves for 10 min. The days of germination was more shortened. and protocorm growth was more promoted in microsonic wave treatment than in non-treatment.
