Non-phenolic allelochemicals in root exudates of an allelopathic rice variety and their identification and weed-suppressive activity
水稻化感品种根分泌物中非酚酸类化感物质的鉴定与抑草活性

Rice (Oryza sativa L.) production is often characterized by a heavy application of herbicides, which may cause environmental problems, while rice allelopathy can potentially be used to improve weed management. This allelopathy can be achieved by the allelochemicals produced by released from living rice roots. Therefore, searching for the allelochemicals from rice has been extensively studied. A range of phenolic acids, such as p-hydroxybenzoic, vanillic, p-coumaric and ferulic acids, were identified as the ...
