The Effect of Psg on Soybean Phenology Stem Mass Pod Mass Leaf Mass Stem Mass (g) Pod Mass (g) Leaf Mass (g) -Psg +Psg -Psg +Psg -Psg +Psg S1: The effect of Psg on shoot mass Black bars represent boxplot central tendency (median). While the edge of the boxes represent upper and lower quartile due to rank, edge of box whiskers represent outlier. +Psg* causes soybean to increase in dry stem mass (left panel) (A). Psg does not have an effect on dry pod mass (center panel) (B); Nor dry leaf mass (right panel) (C): (ANOVA p <0.05*)
