大白菜健、病株根际细菌荧光反应及产HCN能力比较研究

The Comparative Studies on Fluorescence Reaction and HCN Production of the Health and Diseased Chinese Cabbage

从大白菜健、病株根际上分离到健株根际细菌２０株，病株根际细菌１９株，对其进行荧光反应和产ＨＣＮ试验，并进行比较。结果表明：健株根际细菌中具荧光反应菌株明显高于病株根际细菌菌株；健株根际细菌产ＨＣＮ能力与病株根际细菌产ＨＣＮ能力无明显差异；健、病株根际荧光菌株产ＨＣＮ能力差异明显。

Twenty and ninety rhizobacteria were isolated from the healthy and diseased Chinese cabbage individually, and their fluorescence reaction and HCN production were compared. The results showed that the rhizobacter amount possesses fluorescence reaction isolated from healthy cabbage was more than those of rhizobacteria from diseased plants, but there was no difference in the HCN production of rhizobacteria between healthy and diseased plants. However, there was significantly difference in HCN production between the fluorescenceproducing rhizobacteria isolated from healthy or diseased Chinese cabbage.
