Figure 3From: cDNA-AFLP analysis reveals the adaptive responses of citrus to long-term boron-toxicityEffects of B-toxicity on leaf gas exchange, total soluble protein, pigments and MDA. (A- C) CO2 assimilation, stomatal conductance and intercellular CO2 concentration. (D) Total soluble protein concentration. (E) Chl a + b concentration. (F) Chl a/b ratio. (G) Car concentration. (H) MDA concentration. Bars represent means ± SE (n =4 or 5). Different letters above the bars indicate a significant difference at P <0.05.Back to article page
