Abstract: Allelopathic effects of Eucalyptus are widely reported and considered the major factor limiting the establishment of native species in eucalyptus forest. Allelopathy is used here to refer to the inhibitory and stimulatory effects of one plant species upon another by the compounds arising from the products of their metabolism. Improved germplasm of Eucalyptus developed through traditional breeding, tissue culture technique and other biotechnology researches are becoming an attractive alternative to other hardwood tree species for wood, pulp and paper, and bioenergy applications in many countries. In Eucalyptus plantations established for research and commercial end use, allelopathy has been raised as a concern for possible negative effects on crops grown in local areas, especially in agroforestry systems..........
