Abstract

After afforestationwith Azadirachta indica(Neem tree)in a dry-hotvalley of upriverof Jinshajiang, soil water dynamics, growth characteristics, and physiology during the rainy and dry seasonswere studied to explore the tree' s drought adaptation mechanisms by random test with three replication. Results showed an exponential relationship between soil water content and water potential.When soil water content decreased to 5.9% with a soil water potential of- 1.5MPa for3 months, A. indica still survived. A. indica grewvery slowly,peak buds died,and most leaves fell in the dry season; howerer, it grew quickly in the rainy season. The tree presented a bent growthpattern. Compared to the dry season, in the rainy seasons there was a decrease in stomatal conductance (76.2%), net photosynthetic rate(52.9%), and transpiration rate(35.1%); also water use efficiency increased. In addition, the photosynthetic physiology of A. indica decreased in the dry season, because drought damaged the photosynthetic system. Through growth and physiological changes, such as reduced transpiration to maintain water balance, A. indica was adaptable to dry-hot valley.[Ch, 7 fig. 1 tab. 16 ref.]
