Three Zn resistant strains (Flavobacterium FCZ05E, Pseudomonas PCZ05B, Pseudomonas PCZ05H) were inoculated to the roots of soybeans in the soil which was amended Zn in the levels of 200 mg/kg and 500 mg/kg respectively. The results showed that the growth of the soybeans inoculated FCZ05H was stimulated, but with no effect on the growth when inoculated PCZ05B or FCZ05E in the soil which was not amended Zn. Dry weight of the plants inoculated PCZ05B was obviously larger than the controls’, and the contents of Zn both in shoots and roots were all lower than controls’ in the soil which was amended 200 mg/kg and 500 mg/kg Zn. The contents of malodialdehyde (MDA) in the roots were lower than control，and POD in the roots was more active when PCZ05B was inoculated to the roots of soybeans in the soil amended Zn in the levels of 200 mg/kg and 500 mg/kg. Whether Chlorophyll contents were higher than the controls or not had not been found except adding 500 mg/kg Zn to the soil. The contents of chlorophyll, MDA and the activities of POD in the roots of the plants inoculated FCZ05E or PCZ05H were not significantly changed when compared with the controls in two Zn adding levels.
