RICE ALLELOPATHY AND MOMILACTONE

Rice has been extensively studied with respect to its allelopathy as part of a strategy for sustainable weed management options. all available information indicates that rice plants possibly release unknown allelochemicals into the neighbouring environments. a large number of compounds, such as phenolic acids, fatty acids, indoles and terpenes, were identified in rice root exudates and decomposing rice residues as putative allelochemicals. among them, momilactone b may play an important role in rice defence mechanism in the rhizosphere for the competition with invading root systems of neighbouring plants.
