测定了黄松、黑松、花旗松、冷杉和云杉幼苗对土壤水势下降的蒸腾反应。结果表明，当土壤水势为-1 ~-2bar时，所有树种的蒸腾速率均开始下降，且下降的程度因树种而异。在土壤水势为-10巴时，松树的蒸腾速率仅为最大值的12%，而冷杉的蒸腾速率为最大值的27%-37%。云杉的反应是中等的。森林科学20：181-186。
Measurement of the transpiration response of ponderosa pine, lodgepole pine, Douglas-fir, grand fir, and Engelmann spruce seedlings to decreasing soil water potential showed that the transpiration rate of all species began to decline at a soil water potential of -1 to -2 bars, and that the degree of reduction of transpiration rate differed with species. At a soil water potential of -10 bars, the transpiration rate of the pines was only about 12 percent of their maximum rate, while the rate of the firs was 27-37 percent of maximum. The response of the spruce was intermediate. Forest Sci. 20:181-186.
