| 개화후 강우 시기가 홍화의 생육과 종실의 품질에 미치는 영향을 구명하기 위해 시험을 수행한 결과는 다음과 같다. 개화후 강우 시기에 따른 지상부 및 꽃 봉오리 병해 발생 정도는 각각 3.3, 1로서 영향을 미치지 않았다. 등숙 비율은 주경은 개화후 $1{sim}5$일 강우시 37.4%, 1차 분지는 개화후 $6{sim}10$일 강우시 63.0%로서 가장 낮았다. 10a당 수량은 무강우의 327kg/10a에 비해 개화후 $6{sim}10$일과 개화후 $11{sim}15$일 강우시 $282{sim}281kg/10a$으로서 각각 14% 감소되었다. 종실의 색도(명도=L)는 개화후 $21{sim}25$일 강우시 73.5, $26{sim}30$일 강우시 69.9로서 무강우 79.3에 비해 크게 낮아졌다. 이상의 결과에서 볼때 수확기 강우에 의한 종실의 품질 손실 방지를 위해서는 개화후 25일까지는 수확을 해야 할 것으로 사료된다. |

| This study was conducted to find out the effect of rainfall time on growth and seed quality in safflower. Rainfall was done artificially and the treatment of rainfall time was divided into 6 parts. Each rainfall treatment was done from the first day of flowering up to the fifth day after flowering, from sixth day after flowering to the tenth day after flowering, from the eleventh day after flowering to the fifteenth day after flowering, from sixteenth day after flowering to twentith day after flowering, from the twenty first day after flowering to the twenty fifth day after flowering and from twenty sixth day after flowering to thirtith day after flowering. Rainfall time after flowering did not affect disease occurrence on the upper part and flower bud of safflower, which were infected at were 3.3 and 1, respectively. Ripened grain found on the main stem and primary branch was 37.4% and 65.0% at first day to the fifth day and sixth day to the tenth day rainfall periods after flowering, respectively. Yield was decreased by 14% in the sixth day up to the tenth day and eleventh day up to the fifteenth day rainfall periods (282-281kg/10a) compared to the one under control (327kg/10a). Hunter's L value was 73.5 and 69.9 in twenty first up to the twenty fifth day and twenty sixth up to the thirtith day rainfall periods after flowering, which decreased significantly to 79.3 under non-rainfall period. Therefore, it can be concluded that the optimum harvest time is twenty fifth day after flowering to maintain seed quality at rainfall time and before harvesting period. |
