Abstract
Tuber yield and content of general component and diosgenin which is a main bioactive property were investigated in order to determine the growth characteristics of round typed yam(Dungeun-ma, Dioscorea opposita L.) and the potential of artificial culture at Suwon, Korea. Sprouting rates of segmented small tubers such as 3, 5, 7, 9, and 12g were respectively 60.3, 80.5, 85.3, 98.6 and 99.3% when they were investigated 30 days after planting. Segmented small tubers of 3, 5, 7, 9, and 12g enlarged respectively to 66, 87, 98, 120, and 140g in the green-house cultivation. Segmented small tubers of 3, 7, 12, 18, and 23g enlarged respectively to 35.2, 124.7, 142.7, 174.8, and 200,7g in the open-air field cultivation.
마산업 경쟁력 제고에 필수적인 대량생산 체계 확립을 위한 둥근마 씨마 생산에 있어서 소절편 크기별 상품 괴경 생산 방법에 관한 연구는 다음과 같다. (1) 분할마를 심은지 30일 후에 3g, 5g, 7g, 9g, 12g씩 분할한 절편의 발아율은 60.3%, 80.5%, 85.3%, 98.6% 및 99.3%를 나타냈다. (2) 하우스재배에서 분할 절편에 따른 괴경 비대는 3g, 5g, 7g, 9g, 12g에서 66g, 87g, 98g, 120g, 140g을 나타냈다. (3) 노지재배에서 분할 절편에 따른 괴경 비대는 3g, 7g, 12g, 18g, 23g에서 35.2g, 124.7g, 142.7g, 174.8g, 200.7g을 나타냈다.
