Figure 1.
Effect of WR10 inoculation on wheat grain yield production and nutrient content. (A) The relative mean number of kernels per spike (KPS) of 30 wheat plants; (B) Relative content of total N in grains; (C) Relative content of K in grains; (D) Relative content of Fe in grains. Content of macronutrients was calculated as mg/g, and that of micronutrients was calculated as mg/kg dry weight (DW). Original data were analyzed by ANOVA pair-wise comparisons using LDS-test and p < 0.05 was considered significant. All data in the figure were normalized to their counterparts in the control group (NC) without inoculation of bacteria. In spraying, soils were sprayed with B. altitudinis WR10 before sowing of wheat; in soaking, wheat seeds were soaked in B. altitudinis WR10 suspension before sowing. a, statistically different from NC; b, significantly different between spraying and soaking groups.
