Fig. 2From: Effect of the inoculation of plant growth-promoting rhizobacteria on the photosynthetic characteristics of Sambucus williamsii Hance container seedlings under drought stressEffects of Acinetobacter calcoaceticus X128 inoculation on the stomatal conductance of Sambucus williamsii Hance container seedlings under drought-stressed condition. Values are means of three repeating groups (twelve seedlings for each repeat group). Bars represent the standard deviation. Different letters indicate significant differences for the stomatal conductance on the same day after inoculation at P < 0.05 by LSDBack to article page
