| Research Abstract |
I studied the drought tolerance and related morphological and physiological traits of tropical trees to evaluate interspecific difference in response to drought stress, because in the tropical areas of Southeast Asia, the decreased precipitation and increased frequency of short-term drought are predicted with global warming. Morphological characteristics of tropical canopy species are closely related with their water use strategies ; species with high photosynthetic and transpiration abilities have large vessel diameter, but large water stress in the daytime, and then high mortality rates during severe drought. In addition, experimental drought treatment induced a high drought tolerance in a tropical emergent species, Dryobalanops aromatica, by the increase of water extraction efficiency, and then saving its water consumption during drought.
