잇꽃 재배시 홍화수확적기 및 이에 따른 종실 (홍화자) 수확적기를 구명하고자 홍화를 개화성기 후 2, 4, 6일, 종설을 개화 성기후 10, 15, 20, 25일에 수확하여 시험한 결과를 요약하면 다음과 같다. 1. 건홍화의 수확적기는 개화후 4일로 수량은 개화 후 2일(28.1kg/10a)에 비하여 유의차가 없었고 색채색차 (${\Delta}Eab$) 로 본 품질도 개화 후 6일에 비하여 1.07로 차이가 작았던 개화 후 4일로 판단되었다. 2. 홍화의 수확유무 및 수확시기에 따른 종실수량은 유의차가 인정되지 않았다. 3. 수확시기에 따른 ha당 종실수량은 개화성기 후 10일 수확 284.8kg에 비하여 수확이 늦추어짐에 따라 백립중이 증가하여 20일 수확시 17%, 25일 수확은 8% 증수되어 홍화의 종실수확적기는 개화후 20일 전후로 판단되었다.

Abstract

This experiment was conducted to determinate the optimum harvesting time of Carthami Flos and grain in safflower. In dry Carthami Flos yields harvested at different days after flowering, threre was no significant difference between 2 days and 4 days, however, yield harvested at 6 days was decreased significantly compared with 2 days after flowering. As the harvesting time were delayed, lightness (L') and redness (a') of dry Carthami Flos were decreased but yellowness (b') of that was increased. Color differences (${\Delta}E'ab$) of dry Carthami Flos between harvesting days after flowering were not visible between 4 days and 6 days but between those (4 days and 6 days) and 2 days were visible. As the result, the optimum harvesting time of Carthami Flos was 4 days after flowering. Grain yields and its components were affected by not harvesting Carthami Flos but grain harvesting time. Threre was no significant difference in number of grain per flower head, percentage of ripened grain between grain harvesting time. However, weight of 1000 grains and grain yields increased until 20 days after flowering. As a conclusion, the optimum harvesting time was 4 days after flowering for Carthami Flos and 20 days for grain regardless Carthami Flos harvesting time.
