| 摘 要： | 不同种源兴安落叶松枝条水势对气候暖化响应的研究结果表明,生长季内塔河、带岭、黑河和松岭兴安落叶松枝条清晨、午间水势变化趋势相似。生长季塔河、松岭、黑河和带岭种源清晨枝条平均水势分别为-0.30、-0.35、-0.37和-0.39MPa,枝条中午平均水势分别为-1.43、-1.51、-1.59和-1.78MPa。生长季塔河、松岭、黑河和带岭水势差均值分别为1.13、1.16、1.22、1.39MPa。

| Abstract: | To study water potential of different provenances of Larix gmelinii branches response to global warming,the findings show in the morning and midday,the branches water potential of the Larix gmelinii growing in Tahe,Dailing,Heihe,Songling were similar during the growing season.The mean in the morning,the valnes were-0.30,-0.35,-0.37 and-0.39 MPa,the midday values were-1.43,-1.51,-1.59 and-1.78 MPa.During the growing season,the mean difference of water potential were 1.13,1.16,1.22 and 1.39 MPa. |
