Germination And Growth

Momilactone B was released into the neighboring environment from rice throughout its life cycle. The rate of momilactone B release from rice increased until flowering initiation, and then decreased. The release rate of momilactone B at the day of flowering started was 2.1 μg plant–1 d–1. On average, a single rice plant released about 100 μg of momilactone B into the neighboring environment over its life cycle. Since momilactone B is a growth inhibitor, these results suggest that momilactone B released from rice plants may serve as an allelochemical to inhibit the germination and growth of neighboring plants.
