FIGURE 2.

Average nodule count in the entire root, taproot, and non‐taproot for six soybean accessions evaluated at three vegetative growth stages in three environments. All graphs show results for each genotype on a per plant basis at each growth stage. The number of replications per environment was 10–12. (a) Total average nodule counts, (b) average individual nodule size, (c) total nodule volume, (d) total average taproot nodule counts, (e) average nodule size of the nodules on the taproots, (f) total taproot nodule volume, (g) total average nodule counts of the non‐taproot nodules, (h) average individual nodule size of the non‐taproot nodules, (i) average nodule size of the nodules on the non‐taproots
