Research on Photosynthetic and Water Physiological Characteristics of 10 Tree Species Used for Ecological Restoration in Dry Valleys

In order to provide theoretical basis of tree selection for vegetation restoration, 10 tree species were chosen for measuring and comparing their photosynthetic, Chlorophyll fluorescence and water physiological characteristics in the dry valley of the Minjiang River. The result revealed the drought resistance characteristics of various plants by analyzing the photosynthetic operation, photosynthetic physiological characteristics, water physiological characteristics and correlations of different plants in arid regions.
