摘　　要：采用对比试验法,研究了盐胁迫对菊花桃等4种碧桃植物净光合速率变化数值、供试材料体内的游离脯氨酸含量、叶绿素含量、可溶性糖含量与供试材料伤害值(电导率变化)等生理生化指标的影响。结果表明:菊花桃、紫叶桃、合欢双色和垂枝桃4个碧桃品种的耐盐能力均较强,其中合欢双色和垂枝桃2个品种抗性更佳。The comparative experimental method was to study salt stress on peach and other four kinds of chrysanthemum plant-Tau magnitude of changes in net photosynthetic rate for the test materials, the body of free proline content, chlorophyll content, soluble sugar content for the test material damage values（conductance the rate of change） and quot;and other physiological and biochemical indexes. The results showed that chrysanthemum, peach, purple leaf peach, acaciacolor, 4 peach weeping peach varieties of salt tolerance were strong, including Acacia color, weeping peach 2 resistant varieties better.
