Principles and Practices
This book provides comprehensive, current scientific and applied practical knowledge on vegetable grafting, a method gaining considerable interest that is used to protect crops from soil-borne diseases, abiotic stress and to enhance growth/yield. Though the benefits of using grafted transplants are now fully recognized worldwide, understanding the rootstock/scion interactions under variable environmental pressures remains vital for grafting-mediated crop improvement. In this book the authors attend to this need and explain the reasons for, and methods and applications of, grafting.
Vegetable Grafting: Principles and Practices covers:
· rootstock breeding, signalling, and physiological and molecular mechanisms involved in grafting;
· beneficial effects of grafting including reducing disease damage and abiotic stress;
· side effects relating to the impact of grafting on fruit quality; and
· practical applications and speciality crops.
Including high-quality colour images and written by an international team of expert authors, this book provides up-to-date scientific data and is also concerned with translating science to the field. It is an essential resource for researchers, advanced technicians, practitioners and extension workers. ; This book provides comprehensive and current scientific and practical knowledge on vegetable grafting, a method gaining considerable interest as an alternative to the use of fumigants to protect crops from soil-borne diseases. ; 1: Introduction to vegetable grafting1.1: Importance and use of vegetable grafting1.2: The process of vegetable grafting 1.3: Problems associated with vegetable grafting1.4: Conclusions2: Genetic resources for rootstock breeding2.1: Genetic diversity2.2: Genebank collections 2.3: Current usage of genetic material in rootstocks2.4: Germplasm collection of other plant families2.5: Concluding remarks3: Rootstock breeding: current practices and future technologies3.1: Introduction3.2: Stacking traits: meiosis or grafting or both?3.3: Developing stable, core collections of germplasm for breeding3.4: Deploying genetic diversity for rootstocks3.5: Grafting as a tool for genetic hybridisation and chimera production3.6: Selection of improved rootstocks3.7: Transgenic rootstocks3.8: Rootstock registration and commercialization4: Rootstock-scion signalling: key factors mediating scion performance 4.1: Introduction4.2: Current knowledge of ionic and chemical signalling between rootstock and scion4.3: Conclusions5: Physiological and molecular mechanisms underlying graft compatibility5.1: Introduction5.2: Anatomical and physiological steps during graft union development5.3: Role of secondary metabolites at the interface in graft incompatibility5.4: Cell-to-cell communication between graft partners5.5: Understanding the molecular mechanisms involved in graft union formation and compatibility.5.6: Methods for examining graft union development and compatibility5.7: Conclusions and future perspectives6: Grafting as agro-technology for reducing disease damage6.1: Introduction6.2: The first step: Managing diseases in the nursery 6.3: Disease spread from the nursery to the field, the example of powdery mildew of watermelons6.4: Intra- and interspecific grafting and their relations to diseases6.5: Biotic or abiotic stress?
