| 摘 要： | 分别用质量浓度为0，250，500，750，1000mg／L的多效唑（PP333）溶液叶面喷布香樟幼树，测定香樟叶片内超氧化物歧化酶（SOD）、过氧化氢酶（CAT）、丙二醛（MDA）、超氧阴离子自由基、电解质外渗率等5项生理指标．结果表明，用质量浓度为500mg／L的多效唑（PP333）溶液喷布叶片，能明显提高香樟幼树的抗寒性． |
| 关 键 词： | 多效唑(PP333) 香樟幼树 抗寒性 |

| Abstract: | With the difference concentration(s0,250,500,750,1000mg/L)of PP333 spraying leaves in Cinnamomuim camphora of seedlings,the five physiological indicators of camphor leaves inciuding superoxide dismutase(SOD),catalase(CAT),malondiadehyde(MDA),oxygen free radica(lO2-),electrolyte leakage rate was determinated.The results showed that spraying leaves with the PP333 of 500 mg/L can enhance the Cinnamomuim camphora seed-lings winter resistance significantly. |
