Figure 1.

The root and shoot developments at 12-day-old seedling stage (black bars) and V3 stage (grey bars) of 13 soybean cultivars and the reference cultivar W82 under normal conditions. Roots and shoots were collected individually for measurement of the length and dry matter (DM) at day 12 after sowing and at V3 stage. (a) Tap root length. (b) Shoot length. (c) Root DM. (d) Shoot DM. Error bars represent standard error (n = 30). Different letters indicate significant difference at each developmental stage according to Duncan's test (P < 0.05 level).
