The phytohormone salicylic acid is found in plants with roles in photosynthesis, transpiration, ion uptake, transport, plant growth and development. It is involved in cell signaling, mediating in plant defense against pathogens. Because of the economic importance, the seed metabolism epecially the accumulation of storage products, became a subject of intensive investigation. The book offers comprehensive understanding of the bochemical changes induced by salicylic acid during seed development and germination of pea (Pisum sativum L.). The book focuses on the changes in Ascorbate peroxidase, acid phosphatase, a-amylase, sucrose synthase and protein contents during the seed development and grmination in pea. In additon to these biochemical studies, the yield and yield components has also been anlysed for salicylic acid treated pea plants. The experiments are well planned and the conclusions are based on data analysis. The current work on seed development and germination in pea will serve as a foundation for further studies in both key phases of pea life cycle. The book is specifically useful for the researchers working/searhing new growth regulators.
