Researches indicate that the membrane structure and function and the content of osmorenlation substance and endogenous hormone change during the adaptation of plants to the low temperature.In order to study the dominant factors which effect on the cold resistance of Taxus chinensis var. mairei ,The authors have determined many physiological targets and analysed them with soft DPS.The PC of the cold hardness of Taxus chinensiss var. mairei has been achieved.The result of PCA indicates that the first PC mirrored the adaptation of the comprehensive action of osmoregulation and membrane protection system to low temperature,and the second PC mainly reflected the adaptation of hormone to low temperature.
