Bacillus subtilis HG-15, a Halotolerant Rhizoplane Bacterium, Promotes Growth and Salinity Tolerance in Wheat (Triticum aestivum)

Figure 4

Effects of B. subtilis HG-15 inoculation on the chlorophyll content and photosynthesis of plants under different salinity conditions (0.15%, 0.25%, and 0.35% NaCl). (a) Chlorophyll A, (b) chlorophyll B, (c) net photosynthetic rate (A), (d) stomatal conductance (gsw), (e) transpiration rate (E), (f) intercellular CO₂ concentration (Ci), and (g) Fv/Fm. Data are shown as the (). Capital letters indicate the difference between CK and HG-15 inoculation under the same salt concentration (Student’s test, ), whereas lowercase letters indicate differences under the three different salt concentrations in the control (or HG-15) group (one-way ANOVA, ).
