白鹤芋的光合特性和水分利用效率
Photosynthetic Character and Water Use Efficiency in Spathiphyllum

研究白鹤芋5个品种的光合特性和水分利用效率。结果显示，不同品种间光合、蒸腾的日变化不同，水分利用效率也不同，其水分利用效率日变化均值依次为Coddy color> Tyler Green>Parrish>S. floribundum>S.cannifolium，前3个品种较其他2个品种水分利用率高，这为日常栽培中的水分管理提供了依据。
The photosynthetic traits and WUE of five Spathiphyllum varieties were studied. The results showed that there were differences among Spathiphyllum varieties in photosynthesis and WUE.The daily average WUE sequence was as follows:Coddy color>Tyler Green>Parrish>S. floribundum>S.cannifolium. These provide theoretical basis for daily cultivation water management.
