| 摘 要： | 为探索ABA对叶子花正常叶和变态叶部分生理生化指标的影响,利用不同浓度ABA溶液处理叶子花正常叶和变态叶,6h后,测定其叶绿素、可溶性糖、可溶性蛋白、游离脯氨酸含量和SOD酶活性.结果表明:处理后,变态叶和正常叶的叶绿素含量,SOD酶活性,游离脯氨酸含量和变态叶可溶性糖含量均先增加后降低,在ABA浓度为100 μmol/L时最大.正常叶的可溶性糖含量、正常叶和变态叶的可溶性蛋白含量在ABA浓度为50 μmol/L时最大.这表明50～100 μmol/L浓度的ABA能提高叶子花的抗逆性.

| Abstract: | The effects of ABA on some biochemical parameters of normal and irregular leaves of Bougainvillea spectabilis Willd were studied.Normal and irregular leaves of B.spectabilis were treated with ABA for 6 hours at different concentrations.Then the contents of chlorophyll,soluble sugar,soluble protein,free proline and SOD enzyme activity were measured.The results showed that the contents of chlorophyll,SOD activity,and free proline of irregular leaves and soluble sugar of normal leaves increased at first and then decreased and they reached maximum when treated with 100μmol/L ABA.The soluble sugar of normal leaves,the protein content of normal and irregular leaves reached maximum when treated with 50μmol/L ABA.This indicated that 50-100μmol/L ABA could improve the resistance of B.spectabilis. |
