Studies on the Duration and Rate of Grain Filling in Rice (Oryza sativa L.) I. Varietal Difference and Effects of Nitrogen
수도의 등숙기간 및 등숙속도 연구 I. 품종간 차이 및 질소의 영향
Abstract
Understanding grain filling characteristics represented by grain filling duration and grain filling rate is import-ant in improving higher yielding varieties and developing better cultural methods of rice (Oryza sativa L.). Recently developed 6 Japonica and 6 Japonica/Indica varieties were grown under 3 nitrogen levels at Experimental Farm of Chungbuk National University in 1986. The range of grain filling duration of 12 varieties was 20.9-39.0 days, while grain filling rate ranged from 53.8 to 136.6 mg. panicle
