中文摘要	[目的]了解乌兰布和沙区17个沙棘品种的抗旱能力,为选择耐旱沙棘树种提供理论依据。[方法]在不同的水分条件下,采用隶属函数值法对其抗旱性进行综合评价。[结果](1)随干旱胁迫的增加,各品种的自然水分饱和亏、束缚水及束缚水/自由水比值、细胞膜透性呈增加趋势。自然水分饱和亏在22.88%~64.85%之间,在胁迫后期,丘依斯克、欧11号、白丘的水分饱和亏接近,处于高水平状态;深秋红、欧11号在束缚水及束缚水/自由水比值处于较高水平;橙色与白丘的相对电导率显著高于其他品种。(2)随干旱胁迫的增加,各品种的叶绿素含量、保水力、光合速率、蒸腾速率及气孔导度呈降低趋势。亚历山大12号的叶绿素含量最高;橙色和向阳的失水速率显著高于其他品种;辽阜1号和深秋红的光合蒸腾速率下降幅度较大、气孔导度下降程度维持在中等水平。 [结论]各沙棘品种的抗旱性由强到弱顺序依次为:辽阜1号>欧11号>深秋红>状元黄>棕丘>植物园>白丘>西伯利亚红晕>丘依斯克>亚历山大12号>橙色>高加索>向阳>巨人>无核>卡图尼>海滨沙棘。
英文摘要	To evaluate drought resistance of seventeen Hippophae rhamnoides in Ulan Buh Desert in order to provide theoretical basis for the selection of drought resistant species. [Methods] Under different soil moisture conditions, subordinate function values analysis was used to evaluate drought resistance. [Results] (1) With the increasing of drought stress, water saturation deficit, boung water and bound/free water ratio, and cell membrane permeability increased. Water saturation deficit ranged from 22.88% to 64.85%, and maintained at the same high level in Qiuyisike, Ou 11 and Baiqiu. Boung water and bound/free water ratio showed a high level in Shenqiuhong and Ou11. The relative electric conductivity in Chengse and Baiqiu was significantly higher than that in the other varieties. (2) As the acceleration in drought stress, the content of chlorophyll, water-retaining capcity, photosynthetic rate, transpiration rate and stomatal conductance showed a decreasing trend. Yalishanda 12 had the highest content of chlorophyll. The rate of water loss in Chengse and Xiangyang was significantly higher than that in the other varieties. Photosynthetic and transpiration rate in Liaofu 1 and Shenqiuhong declined by a large margin, while the decline of stomatal conductance in Liaofu 1 and Shenqiuhong maintained at a moderate level. [Conclusion] The drought resistance of seventeen Hippophae rhamnoides showed as follows: Liaofu 1>Ou 11>Shenqiuhong>Zhuangyuanhuang >Zongqiu>Zhiwuyuan>Baiqiu>Xiboliyahongyun>Qiuyisike>Yalishanda 12>Chengse>Gaijiasuo>Xiangyang>Juren>Wuhe>Katuni>Haibin.
