| 摘要: |
| 为了解过氧化物酶、IAA氧化酶和过氧化氢酶在植物不定根分化、发育过程中的作用,在实验室内分析测定白花泡桐[Paulownia foutunei(Seem.) Hemsl]不定根分化过程中过氧化物酶、IAA氧化酶和过氧化氢酶活性的变化。结果表明:过氧化物酶在根分化0d~2d的活性下降37.6%,随后逐步上升;IAA氧化酶活性在0d~2d内迅速下降了52.6%,随后逐步上升;过氧化氢酶的活性在不定根分化过程中逐步上升,0d~4d酶活性从5.1上升到10.5,从第4天开始活性增加减慢。 |

| Abstract: |
| The activity of peroxidase、IAA oxidase and catalase of Paulownia foutunei (Seem.) Hemsl were analyzed in the development of adventitious root of Paulownia foutunie (Seem.) Hemsl. In zero day to 2 days of adventitious root development, peroxidase activity decreased by 37.6% and then increased steadily;IAA-oxidase activity decreased by 52.7%, and then increased progressively. Whereas catalase activity increased from 5.1% to 10.5% from zero day to four days of adventitious root development, and increased slowly in activity after four days. |
