Abstract

In forest plantations, many types of plant spp. grow together for long periods and hence, are ideal location for allelopathic research. The high yielding exotic spp. introduced to increase productivity of forests are most allelopathic than indigenous spp. These reduce the vegetation diversity and understorey flora due to inhibitory allelopathic efforts. The information about transformation and degradation processes of allelochemicals in soil is little known, hence, needs further studies. Various types of stresses (biotic/abiotic) greatly influence the production and release of allelochemicals in environment. Eucalyptus globulus is most allelopathic tree spp. in forest plantations and its leachates contain large number of allelochemicals. Allelopathic interactions are mediated by a mixture of many allelochemicals. Under field conditions, the concentrations of individual allelochemicals is too low to cause allelopathic effects.
