Abstract

Abstract: In order to explore the effects of soil microorganisms domesticated by different plants on wheat （Triticum aestivum L.） growth, a controlled experiment was conducted using the cultivar Jimai 22 as the target crop. Seven treatments were established, including non-inoculated microorganisms control (CK1), inoculation with wheat-domesticated soil microorganisms(CK2), inoculation with Chinese cabbage (Brassica rapa)-domesticated soil microorganisms, inoculation with green foxtail (Setaria viridis)-domesticated soil microorganisms (T2), inoculation with alfalfa (Medicago sativa)-domesticated soil microorganisms (T3), inoculation with abandoned farmland soil microorganisms (T4) and inoculation with woodland soil microorganisms (T5). The results showed that all treatments significantly affected wheat aboveground and belowground biomass, with T1 showing the highest biomass accumulation. Significant differences were observed in plant height, leaf area, specific leaf area (SLA), and root-to-shoot ratio among treatments. Transpiration and photosynthetic rates varied significantly across treatments. Photosynthetic rate showed a significantly positive correlation with plant height (r=0.74, P<0.001) and a significantly negative correlation with SLA (r=-0.49, P=0.030). In summary, soil microorganisms domesticated by different plants affected wheat growth significantly, and this might be mediated by changes in wheat energy allocation strategy and physiological status. The research indicated this method was feasible and had certain potential in regulating wheat growth.

Key words: soil microorganism, domesticated by plant, wheat（Triticum aestivum L.）, growth
