Allelopathy
Definition
A bio-ecological phenomenon whereby a plant produces and releases secondary chemical substances (called allelochemicals) into the environment, which are biochemicals capable of directly influencing the growth, development, germination, or survival of other plant organisms in its vicinity. Structurally, allelopathy functions as a chemical mechanism for territorial competition, exerting inhibitory (negative) or, more rarely, stimulatory (positive) effects on neighboring species.
