Review of the biotechnological applications of rice allelopathy in agricultural production: Biotechnological rice allelopathy

An improvement in the allelopathic potential of rice will have a great impact on both low-input and high-input management systems. Allelopathy alone is not likely to replace other weed control practices, but it surely functions as a component of integrated weed management technology. All?l?ath? is th? ?r???? wh?r?b? an organic ?h?m??al (all?l?h?m??al) that is r?l?a??d from one ?lant influences the growth and d?v?l?m?nt of other plants. Allelochemical biosynthesis, release, environmental fate and action on other plant species can depend on genetic factors or on the environment and their interaction. As a result of these interactions, allelopathy is a complex phenomenon with limited repeatability. The term allelopathy has undergone several changes and it has been defined as any direct or indirect harmful or beneficial effect of a plant on another through the production of chemical compounds that it releases into the environment. Rice allelopathy is one of the modes of interaction between receptor and donor plants and could exert either positive effects or negative effects. The development of genetic modification by enhancing crops with allelopathic traits should be done cautiously, given the ecological risk (untoxic and safe for humans and the ecosystem, crop productivity, the ratio of benefit and cost etc.). Finally, this article reviews the agricultural production system allelopathy of novel applications, including the role of allelochemical consortia and their potential use in no-tillage cropping systems, cover crops or mulches.
