ALLELOPATHY AND ITS INFLUENCE ON THE COMPETITION OF PLANTS IN ECOSYSTEM ABSTRACT
The term allelopathy, first introduced by Molisch (1937) its refers to biochemical interactions among plants and under appropriate conditions, these chemical may be released into the environment generally the Rhizosphere in sufficient quantities to effect neighbouring plants and to ecosystem and these substances had a big role for in ecosystems for defence, inhibitors, poisons and toxin products.
The crops and weeds are known to exhibit allelopathy by releasing water-soluble phytotoxins from leaves, stems, roots, rhizomes, stolon, flower, fruits, seeds, glandular and trichomes to compete with crops for nutrients and environmental variable appear to toxic to the germination and growth of the plants, the phytotoxic effects can be attributed either to allelochemicals present in the plant or weed residues or to microbial toxin produced during decomposition.
