摘　　要：分析不同种源兴安落叶松枝条水分饱和亏缺和保水力对气候暖化的响应的结果表明,黑河、松岭、带岭和塔河兴安落叶松枝条水分饱和亏缺平均值分别为20.48%、20.39%、18.98%和18.44%;平均失水率分别为56.33%、52.77%、50.65%和53.03%。表明在气候变暖条件下,塔河种源兴安落叶松组织需水程度最低,维持组织水分平衡能力最强,而黑河种源维持水分能力较弱;带岭种源兴安落叶松离体状态下保水能力最强,塔河和松岭相当,黑河最低。The effect on water saturation deficit and water - holding ability of different kinds of Larix gmelinii to global warming was analyzed. The result showed that average water saturation deficit for Heihe, Songling, Dailing and Tabe was 20. 48%, 20. 39%, 18.98% and 18.44%, respectively. The average water- losing rate for Dailing, Heihe, Songling and Tahe was 50. 65% 56. 33%, 52. 77% and 53.03%, respectively. The above results showed that Larix gmelinii from Tahe had the highest capability to maintain tissue water balance while Heihe was the lowest; The resistance to water lose from high to low was： Daihnz. Tahe. Sondina and Heihe.
