From the preface The enigmatic silent and complex biochemical interactions among plants including microbes generally go unnoticed in nature but lead to changes in vegetation structure composition and species diversity. Such biochemical interactions termed as allelopathy have emerged as a full fledged scientific discipline falling within the framework of chemical ecology. Allelochemicals are produced in plants as defensive compounds and upon release influence the growth and development of biological systems in different ecosystems. Allelopathy is now viewed with multifaceted approach and is recognized as a key factor in vegetation patterning succession forest regeneration and influencing growth and yield of other plants. In agroecosystems the influence of allelopathy on crop plants was probably realized from the beginning of the civilization when agriculture began. Generally it is viewed as a causal factor in decreasing yield of crop plants. Accumulation of allelochemicals in the fields causes soil sickness and thereby the growth and yield of crop plants particularly when the same crop is grown continuously in monocultures. The problem of soil sickness is attributed to autotoxicity (autoallelopathy). During the last few years this science has attracted the attention of scientists world over because of the pesticidal potential of allelochemicals. Allelopathic interactions in agricultural fields also influence soil microbial ecology nutrient dynamics and various biotic and abiotic factors. 448 pp.…
