Abstract
本試驗目的在於探討稻穀胴割粒率受氣候環境因子與成熟期的影響，初步結果顯示，同一品種在相同的栽培管理與收穫調製下，因年度與期作不同，可顯示不等的胴割粒率，除年度間有明顯差異外，期作間亦有極顯著差異，一期作較二期作平均高出17%。造成此種差異之主要原因，可能係受氣候環境因子之影響所致。Five commercial rice varieties were used for studing the effect of climatic environment and ripening stage on the cracked kernel rate(CKR)of rice at Chia-Yi Agricultural Experiment Station from 1987 to 1989.Preliminary results indicated that the CKR of rice has a great differences among the years and cropping seasons. Under a similar cultural method and post harvested treatment, the CKR in the first crop was about 17.0%higher than that in the second crop seasons.
