第一、二期作水稻產量構成要素對產量影響分析

Effect of Yield Components on the Yield of Rice in Centra Taiwan

摘要


20個梗稻及秈稻品種在台灣中部一、二期作栽培,記錄不同產量構成要素及由路徑分析方法分析,鑑定穗數及一穗粒數為影響稻穀產量最重要因素,由路徑分析結果顯示該等特性對產量貢獻最大,充實率對產量貢獻比較小,由此結果推論大穗與高分?及短桿之株型將適合於台灣中部。

並列摘要


Twenty japonica and indica varieties of rice were planted in both 1st and 2nd crops in central Taiwan. Various yield components were recorded and analyzed by the method of path analysis. Number of grains per panicle and panicle number per unit area were identified to be the most important component affecting the grain yield. Both characters contributed greatly to grain yield as revealed by the result of path analysis. The degree of contribution of percentage of filled grains to yield was rather small. It is inferred from this result that the plant type of heavy panicle weight with high tillering capacity and short stature should be adopted in the central Taiwan.
