木麻黄根瘤内生菌的分离、培养和回接

ISOLATION, CULTURE AND INOCULATION OF FRANKIA FROM THE NODULES OF CASUARINA

从福建、广东、海南岛的木麻黄根瘤中分离到16株内生菌,它们都具有Frankia菌的典型形态特征。回接鉴定表明,除4株不侵染原寄主植物外,其余12株均具有侵染能力。但各菌株的侵染能力不同,这些菌株在培养基上的培养特征有一定的差异,实验菌株在BAP培养基上生长最好,在Jan Blom、Qmod等培养基上生长较差。

Sixteen endophytic actinomycetes were isolated from the nodules of Casuarina equisetifolia planted in Fujian, Guangdong and Hainan island. All of them have the typical morphological characteristics of Frankia. 12 out of 16 strains have infecting abilities, but infecting abilities of these isolates are different from each other. The strains showed differences in cultural characteristics. The tested strains grew well on BAP medium but grew poorly on Jan Blom or Qmod medium.
