摘要：

The objective was to test the single and combined use of Pseudomonas spp. and Glomus versiforme on the stress of high zinc (Zn) concentration in soil on corn growth as such data are little. Accordingly, in a greenhouse research work the effects of Zn concentrations (control, 100, 200 and 300mg kg (-1) ) and the microbial treatment (control, Pseudomonas spp. and G. versiforme) were tested on corn (single cross 704) growth. Almost three months after planting, plants were harvested. Plant dry weight and Zn uptake were determined. Zn significantly (P = 0.01) affected different measured parameters. The microbes increased plant dry weight related to the control treatment and the highest increase was related to the bacterial application (1.28times higher). Both bacteria and mycorrhizal fungi and their combined use decreased Zn concentration in plant. The right combination of soil microbes can efficiently affect the process of bioremediation with respect to plant properties.
