Abstract
玉米吐絲前的營養生長可能影響子粒產量表現，本試驗以玉米品種臺農一號為材料，調查營養生長期問植株物質與氮素的累積與分配性狀，同時探討栽培密度的作用，以對其產量生理有進一步的瞭解。於1991及1992年秋作進行試驗，行距均為75cm, 1991年採用株距11、22及44cm三種處理，1992年採用11與22cm兩種株距，又於雄穗分化始期將部份植株株距自11cm問拔為22cm；在播種至吐絲期間連續取樣，分析不同器官之乾物質與氮素累積性狀。Information pertaining to the growth characteristics of corn during vegetative growth is limited. The purpose of this experiment was to investigate the patterm of dry matter and N accumulation of corn hybrid Tainung 1 from sowing to silking and to study their responses to plant spacing treatments. Field experiments were conducted in the fall crops of 1991 and 1992 with a row spacing of 75cm. Within-row spacings were 11, 22, or 44cm in 1991, and 11 or 22cm in 1992. In 1992, the spacing was altered from 11cm to 22cm in part of the plots by thinning the stand at tassel initiation.
