R1 Stage: Beginning Bloom

R1 Soybean Stage: Beginning Bloom

At least one flower appears on the plant on any node on the main stem. This is beginning bloom. The plant is at the V7 to V10 stage and typically is 15 to 18 inches tall. Flowering always begins on the third to sixth node, depending on vegetative stage. Flowering progresses up the plant and the branches. In each raceme, the pods closest to the base are the most mature. Primary racemes (flower clusters) develop ahead of secondary racemes. Vertical roots grow rapidly and continue to R4 or R5. Secondary roots and root hairs also continue to grow.
