Fig. 4From: Transcriptomic and physiological analyses of Trichoderma citrinoviride HT-1 assisted phytoremediation of Cd contaminated water by Phragmites australisEffects of strain HT-1 on the photosynthesis of P. australis in different concentration of Cd, A chlorophyll content, B net photosynthetic rate (Pn), C leaf stomatal conductance (Gs), D intercellular CO2 concentration (Ci), E transpiration rate (Tr). Values are mean ± SD (n = 15 plants). Different letters abovethe bars indicate the differences are significant at p < 0.05Back to article page
