옥수수 초형별 재식밀도에 따른 생육 및 수량반응
Growth and Yield Response of Corn Hybrids with Different Canopy Types to Planting Density
초록
초형이 다른 옥수수의 재식밀도에 대한 반응차이를 구명하고자 직립형 초형과 수평형 초형 교잡종을 재식밀도를 달리하여 재배하고 종실수량 및 주요형질을 조사한 결과를 요약하면 다음과 같다. 1. 공시된 4교잡종 모두 고밀식(10,000주 /10a)하에서 종실수량이 감소하였으나 직립형 교잡종보다 수평형 교잡종인 Ga209
Grain yields of errect-leaved corn hybrids were reported to be increased as planting density(PD) increased compared to those of horizontal leaf type hybrids. This trial was conducted to investigate the difference between errect and horizontal-leaved hybrids in response to different PD. Grain yields of both type hybrids were decreased at the highest PD, however, that of horizontal-leaved hybrid, Ga209
