| 摘 要： | 联合固氮菌-催娩克氏菌（Klebsiella oxytoca NG13/pMC73A)接种木栖植物桃金粮种（Myrtaceae)桉树属（Eucalyptus)的苗木，研究它们之间相互作用关系。扫描电镜观察结果表明；联合固氮菌不但可以在桉树根表定殖，而且还可进入根内定殖，并在接种桉树的根际，根表和根内均分离到该菌，接种联合固氮菌能刺激桉树根系的分泌作用，并对根系分泌物的氨基酸，糖及激素的含量有所影响，联合固氮菌对桉树生长有明显的促进作用。

| Abstract: | The interaction of Klebsiella mytoca NG13/pMC73A with Eucalyptus were studied. The results showed that the root surface and even the inner cortex of Eucalyptus were colonized by K. oxytoca. The K. oxytoca was reisolated from rhizosphere, root surface and inner root of inoculated Eucalyptus. The inoculation with K. oxytoca stimulated the excretion of Eucalyptus root and affected the contents of amino acids, carbohydrates, phytohormones of root exudates. The seedlings of Eucalyptusto to inoculation with K. oxytoca increased growth, total dry matter and N content by 29.81% - 100.40% after 3 months in comparinson to the uninoculated seedlings. |
