| 摘 要： | 研究了10个树种一年生实生苗主要光合和蒸腾性能对根际水分胁迫的响应。在水分胁迫条件下，其生理过程均受到显著影响，不同树种对水分胁迫的响应不同，树种间响应值的变化表明其抗旱性的差别，将其响应值用模糊数学隶属函数统计方法进行综合评判得出：金链树、紫穗槐、香椿、木瓜抗旱能力较强；沙枣、杜仲、柠条、国槐次之；葛藤、合欢抗旱能力较差。

| Abstract: | er: The response of main photosynthesis and transpiration indexes of ten tree species in the north-west of china to water stress at rhizosphere was investigated with one-year-old seedlings. The physiological indexes were significantly affected by water stress. Each species showed different photosynthesis and transpiration response to water stress .The response index of different species represented their resistant capability to water stress. The index analysis of ten tree species by comparison and statistics of subject function showed that Laburnum alpinum, Amorpha fruticosa, Toona sinensis, Chaenomeles speciosa had strong drought resistance; Elaeagnus angustifolia, Eucommia ulmoides, Caragana korshinkii were in the middle level and Pueraria thunbergiana, Albizzia julibrissin had a poor resistance. |
