This book 28 chapters is divided into seven sections. Section one includes five chapters describing the structure of seed optimum conditions for seed germination physiological and biochemical changes at cellular level. Section two describes leaf area growth indices senescence and abscission. Allelochemicals present in soil or plant can create chemical stress which may change the plant water status plasma membrane properties chlorophyll stability and waxes present on the organ surface. Methods to determine all these parameters are described in next four chapters in section three. These sites can be explored by estimating chlorophyll content chlorophyll fluorescence photosystems I and II activity carbon dioxide exchange rate activity of CO2 fixing enzymes intermediate metabolite level photosynthate partitioning respiration and finally the crop growth dynamics. Methods to determine extent of all these sites are explained in seven chapters in section four. The main use of changed physiological process is at the gene level for which estimation of nucleic acids is very critical. It is briefly explained in section five. Section six has seven chapters. Basic procedure to process the test plant material for microtomy use of light and electron microscopy to study cellular changes measurement of cellular dimensions stomatal index and frequency pollen viability and in vivo pollen germination and histochemical localization of important enzymes and metabolites are the core topics. Currently tissue cultures are commonly used to study the precise effect of allelochemicals on callus growth and differentiation. To achieve these objectives techniques of tissue cultures is described under Section six. 314 pp. N° de ref. del artículo 63380
