Preliminary Studies on the Distribution Character of Endophytic Bacteria in Cabbage

In order to probe into the distributing character of endophytic bacteria in cabbage and develop excellent bio-control preparation,the studies on the quantities distribution and morphological character of endophytic bacteria in different organs from two kinds of cabbage were conducted.The results showed that there were a lot of endophytic bacteria in seed,root,stem and leaf of the cabbage plants.The distributing character of endophytic bacteria varied with organs and types.Population of the endophytic bacteria in root was more than the other organs.Gram positive bacteria and Bacillus spp.were the primary endophytic bacteria population in cabbage.When there were a lot of endophyitc bacteria in the seed of one type,a lot of endophytic bacteria would exist in other organs of this type.When the cabbage was cultured in sterile condition,the quantities of endophytic bacteria were more than that cultured in natural condition.
