摘　　要：测定了盐分胁迫条件下．消香乳、红花、田菁、碱苋菜、碱蓬的营养生长、质膜透性、脯氨酸含量及Ｎａ￣＋和Ｋ￣＋含量的变化．结果表明，随着外界溶液中ＮａＣｌ浓度的增大，消香乳的生长受抑制的程度依次加重，质膜透性增大，脯氨酸和Ｎａ￣＋含量增加，Ｋ￣＋含量降低；而红花、田菁、碱苋菜的生长、质膜透性、脯氨酸含量，在低盐浓度（１００ｍｍｏｌ／ＬＮａＣｌ）下变化不大，碱蓬在低盐浓度（１００和２００ｍｍｏｌ／ＬＮａＣｌ）下，其生长则明显好于对照，只有在高盐浓度下，这四种植物才开始受盐害，生长受抑制、质膜透性增大、脯氨酸和Ｎａ￣＋含量升高、Ｋ￣＋含量降低。这五种植物的耐盐性由大到小依次为：碱蓬、碱苋菜、田菁、红花、消香乳。The salt tolerance Schinus molle,Cartharaus tinctorus,Seshenia cannabina,Anzaranthus sp. and Suaeda salsa was measured.The results showed that the growth ofseedlings of Schinus molle slowed down,membrane permeability and contects of proline andNa￣+ increased,the K￣+ contect decreased under salt stress。However,there were no greatchangs in growth,membrane permeability and proline content of Cartharaus tinctorus,Sesbe-nia cannabina and Amaranthus sp。 moreover,the growth of Suaeda salsawas much better thanthat of the control plants under salt stress。Only under high NaCl concentration did theplants are injured NaCl。
