Figure 4: Statistics of normalized hole volume vs. normalized hole number of known protein and oil content soybeans.

P_48.7O_19.2 (Meng), P_42.5O₁₅ (Fu), and P_33.9O_23.6 (Tiefeng) are three different cultivars of soybeans with varying protein and oil content. Seven seeds were averaged for each cultivar. The asterisk (∗) indicates significant differences compared with holes in P_48.7O_19.2 (P < 0.05; one way ANOVA test). The pound sign (#) indicates significant differences compared with holes in P_42.5O₁₅ (P < 0.05; one way ANOVA test). The bars indicate standard error. Statistically not significant differences with P > 0.05 are not indicated.
