Ecophysiological effect of xylem embolism in six tree species
六种木本植物木质部栓塞化生理生态效应的研究

Xylem embolism and water potential of six tree species was measured for fourteen months.The results showed that xylem embolism could directly cause the loss of xylem hydraulic conductivity.The influence of xylem embolism could be expressed by vulnerability curves.Two types of vulnerability curve models for the six deciduous broad leaved tree species were established,through which the theoretical value of parameters could be determined and their physiological meanings were also discussed.Analysis showed tha...
