摘要
采用盆栽试验对土壤不同干旱程度下拔节期豫麦54水分生理特性进行研究。结果表明,蒸腾速率、光合速率、叶水势、叶片相对含水率、地上部干重和根干重随土壤水分的减少均呈降低趋势,饱和亏和根冠比呈上升趋势。
The experiment in the water physiology of Yumai 54 under different soil drought was conducted. The results showed that transpiration rate, photosynthetic rate,leaf RWC, water potential, dry material weight,and root dry weight were decreased with soil water decreasing; and leaf WSD and font/shoot ratio were inereased with soil water decreasing.
