Allelopathy in Agroforestry: A Review
2024
Melkania, Niranjan. P.
The growing environmental thrusts due to diverse anthropogenic influences, as evident in the form of soil sickness, replant problem, rapid encroachment by some species within and beyond their parental ecosystems, re-vegetational patterns around a tree, etc., and designing sustainable multifunctional land use systems and practices like agroforestry over the past 50 years had made it possible to realize that the overstorey ligneous species have also direct influences through release of certain secondary chemicals into the environment. Such influences have been studied under a specialized subject called as "allelopathy". This contribution is an attempt to put forward the research on allelopathy as expressed by overstorey ligneous species of natural forests and agroforests in India besides summarizing allelopathic genera reported elsewhere. It is suggested that "allelopathy" may be recognised as a natural characteristic of the donar species, and be utilized scientifically for the benefit of humankind following through integrated long-term laboratory-cum-field studies.
