【Abstract】 This paper chiefly gives account of the fluctuation modes of transpiration intensity, water metabolism rate, water deficiency and foliar water content, etc., for different clones under the influence of low temperature and drought during wintering. The adaptabilities of the clones studied are varied though they have been planted in the northern part of South China for some years. The difference among the fluctuation modes is also suggested.更多还原
