摘要: 以野生、抗旱、耐盐性较强的草木犀、柠条、银合欢、伞房决明、刺槐、沙冬青、白刺、二色补血草、柽柳、白沙蒿、沙枣、樱桃、续随子等13种植物的实生幼苗为试材,通过比较不同浓度NaCl胁迫下离体叶片细胞相对膜透性的变化,分析这些植物的耐盐性。结果显示, 6种豆科植物的耐盐性依次为:柠条>银合欢>刺槐>草木犀>沙冬青>伞房决明;5种灌木类植物的耐盐性依次为:柽柳>白刺>柠条>沙冬青>伞房决明;4种乔木类植物的耐盐性依次为:银合欢>刺槐>沙枣>樱桃;4种草本植物的耐盐性依次为:二色补血草>续随子>白沙蒿>草木犀。

Abstract: The salt tolerance of wild plants was studied with leaves of 13 species seedings, Melilotus suaveolens Ledeb, Caragana intermedia, Leucaena glauca, Cassia corymbosa, Robinia pseudoacacia L., Ammopiptanthus mongolicus (Maxim.) Cheng F., Nitraria sibirica, Limonium bicolor Kuntz., Tamarix chinensis, Artemisia sphaerocephala, Elaeagnus angustifolial, Cerasus szechuanica, Euphorbiae Lathyridis, and under different NaCl concentrations, the changes of cell membrane relative permeability in Vitro were compared. The results show that the salt tolerance of six leguminous plants was Caragana intermedia>Leucaena glauca>Robinia pseudoacacia L. >Melilotus suaveolens Ledeb>Ammopiptanthus mongolicus (Maxim.) Cheng F. >Cassia corymbosa respectively, the salt tolerance of five bush plants was Tamarix chinensis>Nitraria sibirica>Caragana intermedia>Ammopiptanthus mongolicus (Maxim.) Cheng F. >Cassia corymbosa respectively, the salt tolerance of four trees was Leucaena glauca>Robinia pseudoacacia L. >Elaeagnus angustifolial>Cerasus szechuanica respectively, and the salt tolerance of four kinds of herbs was Limonium bicolor Kuntz. >Euphorbiae Lathyridis>Artemisia sphaerocephala>Melilotus suaveolens Ledeb respectively.
