Effects of Si application and Pga inoculation on light response parameters of oat leaves. (A), maximum photosynthetic rate (P nmax); (B), light saturation point (LSP); (C), light compensation point (LCP); (D), dark respiration rate (Rd). CK, no Si application and no Pga inoculation; +Si-P, 1.5 mmol·L–1 Si application and no Pga inoculation; -Si+P, no Si application and Pga inoculation; +Si+P, 1.5 mmol·L–1 Si application and Pga inoculation. Data are expressed as mean ± SE (n=3). According to Duncan’s multiple comparison tests among treatments, different letters on bars show significant differences at 0.05 level of probability.
