Abstract

Objective: the effects of ozone concentration on the content of N and P in soybean. Methods: Taking Glycine max (L.)Mer. as an experimental material, the pot experiment was implemented in the open top chamber (OTC). The Three treatments with three replicates for each treatment were deployed: CK(atmospheric ozone concentration,45nmol/mol)and T1((80±10)nmol/mol)and T2((110±10)nmol/mol),it was sampled in the branching period, flowering and podding to determinate the content of N and P in soybean roots, stems and leaves at different times. Results: Compared to the CK, with the increasing of ozone concentration,(1) content of N was decreased(P<0.05) in leaves at podding, and it was increased in other organs at each stage (P<0.05); (2) content of P was decreased(P<0.05) in root at flowering and leaves at branching, and it was increased(P<0.05) first and then decreased at podding, other organs are increased(P<0.05) in each stage. Conclusion: the content of N and P in roots, stems and leaves of soybean were different at different ozone concentrations, provide experimental data and scientific guidance for the assessment of effects of O3 stress on soybean.
