Abstract
溫度是水稻生育的必要環境因子，由發芽至穀粒成熟都需受溫度的調節，瞭解水稻生育對溫度的反應機制與變異，將有助於水稻栽培規劃與品種選育。由於穀粒充實對溫度的反應可直接影響稻米的理化性質，而米質改良是目前臺灣水稻發展的主要目標，因此本章將討論溫度對水稻穀粒充實及稻米品質的影響。內容首先回顧臺灣一、二期水稻生育期及充實期間的溫度變化特性，溫度對穀粒生育與充實的一般影響；再較深入討論溫度對穀粒內主要蓄積大分子澱粉與蛋白質生合成的調控，其對稻米理化及口感性質的效應。文中也提出本研究室實際的試驗結果，最後並歸納出建議的因應措施作為臺灣相關研究與栽培操作的參考。
Temperature is an essential environmental factor for rice development and culture. Taiwan is located in subtropical area with two rice crops a year. The fluctuation of temperature during each crop is differed from other temperate countries where japonica rice is cultivated. Therefore, knowledge of the relationship between rice development and temperature should benefit the design of culture manipulation and breeding strategy. Improvement of grain quality has been the major objective of rice program in Taiwan. Temperature effects on grain filling may directly influence grain physical-chemical properties. The present chapter, thus, would focus the review and
discussion on the temperature effects on grain development and filling, starch and protein accumulation, and palatability. Comments and suggestions for current and future researches to improve grain quality under Taiwan’s temperature environment are also proposed in the context.
