比较测定了水、旱地梨树的叶片解剖构造、气孔分布密度与相对开张度、气孔传导率、蒸腾速率以及光合速率。
Anatomic construction, density and relative opening degree of stomata, stoma conductivity, transpiration rate, and photosynthetic rate of pear leaves of both irrigated and dry land were tested.
结果表明，蒸腾速率、叶 水势、叶片相对含 水率、耗 水量和耗 水系数均随十壤 水分的减少而呈降低趋势。
The results showed that the transpiration rate, leaf RWC, water potential, water-consumption and water use coefficient were decreased with soil water decreasing.
