摘要: 本文测定了柽柳属7个种对NaCl、Na2SO4、NaHCO3、Na2CO3等4种盐类的耐盐极限、同化枝细胞液浓度、同化枝灰分含盐量;调查了7种柽柳的造林成活率及第2年保存率。应用主成分分析法对7种柽柳的耐盐性进行了数量化研究。7种柽柳耐盐性强弱的顺序为:短穗柽柳>甘肃柽柳>长穗柽柳>多花柽柳>甘蒙柽柳>山川柽柳>多枝柽柳。

关键词: 柽柳, 耐盐性, 主分量分析

Abstract: The maximum resistances of seven Tamarisks to Nacl, Na2SO4, NaHCO3, and Na2CO3 were tested and observed, in the meantime, the cytolymph density, ash content of assimilatory branches and survival rates in the first two years were also observed. The resistibilities to salts of seven Tamarisks were quantitively studied by using PCA method and can be ranked the order:Tamarix laxa > T. kansuensis > T. elongata. > T. hohenackeri > T. austromongolica > T. arceuthoides > T. ramosissima.
