Abstract
臺灣地區水稻產量有明顯的期作性差異，由於兩期作水稻生育環境不同，如能確定對供源與積儲關係的影響，將有助於達成提高單位面積產量之目標。本項研究以臺農67號品種為材料，於1989年第二期作至1992年第二期作進行田間試驗，探討不同次位分蘖的產量表現，並以栽培密度方式改變植株供源與積儲關係，解析期作間產量效率差異的原因。
The purpose of this study was to investigate the source-sink relationship of rice plants for a better understanding of the physiological causes of low grain yield in the second crop season. Experiments were conducted from 1989 to 1992 to study the effects of tiller orders and changing planting densities on the performances of agronomic and physiological characteristics of rice plants.
