The Dynamic Of Non-anaerobic Rhizobacteria Of Tomatoes

The bacteria wilt of tomatoes prevails worldwide. It has led to serious results. It invades mainly from the roots and the wounds of plants, increases and goes upward in the vessel, causes the whole plant get systematic wilt and die at last. The pathogen, which used to be assigned as Psendonomas, is a member of Ralstonia. It can infects various plants. The pathogen is permanent dweller in the soil. So far diseases like it no efficient way is found to prevent them.The activities of rhizobacteria must have influence on the invading of the pathogens which causing the plant's systematic diseases. Large amount of researches have reached the result that there is an intimate relationship between the soil-spread diseases and the rhizobacterial. And it is proved that larger population of bacteria and more kinds of groups can lead to stronger ability to antagonize the pathogensSelecting bacteria from the rhizosphere of tomatoes to inhibit the pathogen of tomato wilt is feasible. As the bacteria come from soil, it should be easier to be located in the rhizosphere. But little is known about the population of rhizobacteria and the interactions among them. This paper is initiated to find the members and total number of the non-anaerobic bacteria at the rhizosphere of tomatoes. At the same time, predominant members were selected and identified.Non-anaerobic bacteria in the rhizosplane, rhizospheric soils, surrounding soils and soils out of the rhizosphere are collected at four different growing phases of tomatoes. The dynamic change of their population and the rhizopherical effects are both analysed.Total 38 predominant strains are selected, which are members of Artgribacter, Cellulomonas.Sporolactobacillus, Bacillus, Derxia, Agrobacterium, Glluconobacter, Xanthomonas and Pseudomonas. Their antagonic effects against each other are tested, so do their antagonic effects against the Ralstonia solanacearum (smith) Yabuuchi et al. Only...
