Methyl jasmonate is a signaling molecule that is mediated through air between plants. It plays important role in activating self-defensive system and induces secondary metabolites production in plants. One of the most important defensive systems in allelopathic rice varieties against associated weeds is to produce and release allelochemicals. Therefore, inducible effects by methyl jasmonate on rice allelochemicals production were investigated under both laboratory and field conditions. The results demonstra...
