Abstract
本試驗採用玉米品種臺農一號為材料，以吐絲期具不同營養生長量但吐絲後具有相似生育環境之處理，探討子粒充實期間植株產量生理性狀表現。於1991及1992年秋作進行田間試驗，行距約為75cm，株距分為11與22cm兩種處理，第一年試驗於吐絲期將部份小區株距自11cm間拔為22cm，第二年於雄穗分化始期與吐絲期進行相同處理，又於吐絲期將部份小區株距自22cm間拔至44cm，分析子粒充實期間不同器官之乾物質與氮素累積性狀，解析對產量的影響。The purpose of this experiment was to investigate the pattern of dry matter and N accumulation by corn hybrid Tainung No. 1 during kernel-filling and its influence on yield performance for plants with differed vegetative growth at silking. Field experiments were conducted in the fall crops of 1991 and 1992 with a row spacing of 75 cm and within-row spacings of 11 and 22 cm. The spacing was altered from 11 to 22 cm in part of the plots by thinning the stand at silking (1991) and at tassel initiation and silking (1992). In 1992, thinning was also performed to enlarge the spacing from 22to 44cm.
