Allelopathic Effect of Invasive Weed, Chromolaena odorata on Seed Germination and Seedling Growth of Cowpea

Binumol.M | Santhoshima.P.P

Abstract: The present study is concerned with the Allelopathic effect of C. odorata on seed germination and seeding growth of cowpea (V. unguiculata) Leaf, stem, root and inflorescence extracts of C. odorata inhibit seed germination and seeding growth of cowpea. The inhibitory effect increased with increase in concentration of the extracts. Treatment with higher concentration showed remarkable increase in the rate of inhibition. In control there was 100 % germination and more growth than other concentration. Inflorescence extract have more inhibitory effect on seed germination and seeding growth. This may be to the presence of more allelochemicals in inflorescence compared to leaf, stem and root.
