摘　　要：将Na Cl和Na2CO3两种盐按比例配制,作为复盐,设置5个盐碱梯度,研究了4种野生宿根地被植物的耐盐性。对本实验中石竹、碱菀、棉团铁线莲和野鸢尾在不同盐碱胁迫下的出苗情况、MDA、脯氨酸和质膜透性进行研究。试验表明,不同植物的耐盐碱能力存在显著差异,p H值为9.0的盐碱胁迫下,只有棉团铁线莲和碱菀能够出苗,4种地被植物均能耐受的盐碱度为p H=8.5,4种植物耐盐碱性强弱依次是碱菀>棉团铁线莲>石竹>野鸢尾。In order to research on the salt tolerance of 4 kinds of wild perennial, we set five salinity gradient, used NaCl and Na2CO3. The experimental materials are Tripolium vulgare Nees;Iris dichotoma Pall.;Dianthus chinensis L. and Clematis hexapetala Pall. We studied the seedling, MDA, proline content and cell membrane permeability under different salt stress. The result showed that, the salt tolerance of 4 plants was different. Tripolium vulgare Nees and Tripolium vulgare Nees can survive under pH 9.0 conditions, and they all can survive under pH 8.5 condition. The salt alkalinity of the 4 plants in turn is Tripolium vulgare Nees, Clematis hexapetala Pall., Dianthus chinensis L., Iris dichotoma Pall.
