| 摘 要： | 尾叶桉的 ML A无性系 (简称 ML A)是难生根无性系 ,尾叶桉的 U6无性系 (简称 U6)、刚果12号桉 W5无性系 (简称 W5)为易生根无性系。MLA各器官的多酚氧化酶 (PPO)活性比 U6、W5的低 ,而 ML A各器官的吲哚乙酸氧化酶 (IAAO)活性比 U6、W5的高。各树种的 PPO活性、IAAO活性及 PPO同工酶均具有器官的特异性。讨论了 PPO和 IAAO与不定根的发生和发展的关系

| Abstract: | Eucalyptus urophylla MLA clone (MLA) was difficult to root species. Eucalyptus urophylla U 6 clone (U 6) and Eucalyptus ABL. 12 W 5 clone (W 5) were relatively easy to root species.The activities of polyphenol oxidase (PPO) in MLA is lower than that of U 6 and W 5,but the activity of indoleacetic acid oxidase (IAAO) in MLA was higher than that of U 6 and W 5.The activities of PPO and IAAO and the isoenzymes of PPO in every species had their specificity in every organ.The relationship between the formation and development of adventitious roots and PPO and IAAO was discussed. |
