초록
벼 등숙기 온도 차이가 쌀의 등열특성에 미치는 영향을 구명하고자 1993년 작물시험장 인공기상실에서 숙기가 다른 3개 품종(오대벼, 화성벼, 동진벼)과 등숙온도(22/16
To clarify the effect of temperature during ripening on grain quality, rice plant which was grown under normal natural conditions untill heading stage was subjected various temperature regimes during grain filling stage. Three varieties, Odaebyeo, Hwaseongbyeo and Dongjinbyeo were used. Grains on primary and secondary-rachis branches were harvested seperately and measured specific gravity, grain size and weight. The optimum daily temperature for grain filling of rice during ripening period was about 22
