【Abstract】 The dynamic variances of water potential of stem top, relative electric conductivity and the vitality of larch seedlings in different airing time were determined in this paper. The results showed that the effects of adverse circumstances on seedlings vitality could be reflected indeed by determined water potential of stem top and relative electric conductivity, so this method is very reliably for forecasting survival rate and initial increment in the planting.更多还原
