水稻葉片特征與水分利用效率的關(guān)系研究進(jìn)展

摘要 水稻不僅是世界主要的糧食作物，同樣也是農(nóng)業(yè)水資源第一大消費(fèi)作物。水分高效利用一直是水稻資源利用效率的研究熱點(diǎn)。從水分利用效率的內(nèi)涵和葉片結(jié)構(gòu)、葉片化學(xué)組成、葉片水力參數(shù)、葉片光合等方面概述了水稻葉片特征及其與水分利用效率的關(guān)系，分析了目前存在的問(wèn)題，并對(duì)未來(lái)研究的方向進(jìn)行了展望。

Abstract Rice is not only the world's main food crops， but also agricultural water resources of the largest consumer crops. Water use efficiency （WUE） has been a research hotspot of rice resource use efficiency. In this paper， the characteristics of rice leaves and their relationship with water use efficiency （WUE） were summarized from the aspects of WUE concept， leaf structure， leaf chemical composition， leaf hydraulic parameters and leaf photosynthesis， the existing problems were analyzed and the future research directions were prospected.

Key words Rice;Leaf characteristic;Water use efficiency;Relationship
