Mean pairs within a column with different letters are significantly different at the 5% probability level according to Duncan’s new multiple-range test. BL₀—no brassinolide application (control); BL₁—brassinolide application at seedling growth stage of soybean; BL₂—brassinolide application at flowering growth stage of soybean; BL₃—brassinolide application at podding growth stage of soybean; BL₄—brassinolide application at seedling + flowering growth stages of soybean; BL₅—brassinolide application at seedling + flowering + podding growth stages of soybean; S₀—1.10 mM/L (control); S₁—32.40 mM/L; S₂—60.60 mM/L; S₃—86.30 mM/L; WAS—weeks after sowing.
