Science is basically a descriptive and experimental gadget. It observes nature, constructs hypotheses, plans experiments and proposes theories. the idea is rarely reflected because the 'final truth', yet continues to be ever topic to changes, adjustments and rejections. The technological know-how of allelopathy similarly has emerged, and exists on an identical footing; our endeavour will be to maintain it clean and cutting edge with addition of more moderen in­ formation and ideas with the rejection of older principles and antiquated innovations. in the past few many years encouraging effects were bought in quite a few points of allelopathic researches. notwithstanding, as well as carrying on with efforts in these kinds of instructions, consistent makes an attempt are to be made to explain the mechanics of allelopathic job in molecular phrases and to find methods and capability to take advantage of it for the welfare of mankind. We consider that multidisciplinary efforts are the single device to accomplish this aim. it's the desire of the editors that this publication will function a record which identifies an built-in method, by which examine either to appreciate and take advantage of allelopathy should be performed. the current quantity arose out of an try to assemble eminent scientists in allelopathy to explain their paintings, of a hugely various nature, lower than one title.

Example text

The conceptual framework can provide the foundation for such a mechanistic model. The input factors will define the setting, the processes will govern the transport of the chemical and the impact assessment should reflect the specific effect of allelopathy. These models should be tested with actual data for their applicability to characterize the fate and transport of allelochemicals in the root environment. Only when 28 Assessing allelochemicals in the soil environment the process of transport of allelochemicals from their sources to their targets is known can the cause-and-effect relationship of allelopathy be ascertained.

Methods for measuring retention can either be on the The processes 25 dynamics of the change of distribution or, more commonly, the resulting change at equilibrium. Unfortunately, the commonly used methodology for characterizing sorption is often of limited value (Cheng and Koskinen, 1986). Many indices of retention do not take into consideration the varying influence of soil properties on the adsorb ability of the chemical. Even when the soil influence is accounted for, the test may not differentiate the physical process from chemical or biochemical transformation processes.
