Figure 3.

Effects of phosphate solubilizing bacteria inoculation on shoot and root length (A), dry weight (B), and total P and N of plant (C). The values are means from three biological replicates. The bars represent the standard errors of the means. CK: un-inoculated seedlings. Sol P: un-inoculated seedlings watered with nutrient solution containing 0.25 mM KH₂PO₄. Single asterisks or double asterisks (* or **) indicate significant differences between negative control and other treatment determined by LSD at p < 0.05 or p < 0.01.
