R esearch progresses in do mestic and overseas on physiological response of tree to drought stress are analyzed from three as pects: the apparent and morphological feature, physiological and b iochem ical characters, molecular b iology and gene expression of drought resistance. M any researchers have worked on the apparent and morphological feature, osmosis- regulating, photosynthesis, chlorophyll fluorescence character istic, activate oxygen metabolism, phytohormone. A few researchers have w orked on themolecular b iology and gene expression of drought resistance. F inally, th is paper proposed prmi ary evaluation methods, indexes, m easures and contents on research ing the drought resistance physiological char acters of tree.
