Download or read book Water Conservation Traits to Increase Crop Yields in Water deficit Environments written by Thomas R. Sinclair and published by Springer. This book was released on 2017-05-11 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores specific approaches that have shown to result in crop yield increases. Research on the physiological understanding of these methods has led to the development of practical applications of plant breeding approaches to genetically improve crops to achieve higher yields. Authoritative entries from crop scientists shed new light on two water-conservation traits: one that is based on an initiation of the decrease in transpiration earlier in the soil drying cycle, and the second that is based on a sensitivity of transpiration rate under high atmospheric vapor pressure deficit that results in partial stomatal closure. Both these approaches involve partial stomatal closure under well-defined situations to decrease the rate of soil water loss. Readers will be able to analyze the circumstances under which a benefit is achieved as a result of the water-limitation trait; and key discussion points in the case studies presented will help answer questions such as what species, which environments, how often will yield be benefited for various crop species? Contributions also review the genetic variation for these two traits within each crop species and the physiological basis for the expression of these traits.

Download or read book Bringing Skepticism to Crop Science written by Thomas Sinclair and published by Springer Nature. This book was released on 2023-01-01 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global food production and climate change among other concerns are societal issues that require major research input from crop science. While suggestions are abundant on how crop science can help to resolve these issues, many of the suggestions come from people who are not actually familiar with the challenges and requirements to modify crop plants grown under field conditions to achieve the necessary improvements. Efforts to alter a gene or even several genes have very rarely proven successful in having impact on crop production under realistic field conditions. This lack of success has not been addressed head on. This book serves as a reminder to crop scientists and others that open, clear-minded assessments of the entirety of evidence concerning a hypothesis is required before making claims of possible increases in crop performance. This attitude of skepticism is not a negative attitude but rather an employment of the cornerstone of scientific investigation based on formation and evaluation of hypotheses. Skeptical analyses are to be presented in the book on some of the common suggestions for improving crop plants. The six specific topics to be addressed are photosynthesis, seed number, nitrogen use efficiency, water use efficiency, crop water loss, and unconfirmed field observations. Each of the topics in this book, will first be reviewed to present the origins of the popular assumptions about how specific plant modification will result in improved crop performance. The review of the background information will be followed by an examination of the evidence, logic, and predicted outcomes for the assumed benefits of the modifications. Finally, each chapter will offer novel, alternate approaches to plant modification that have documented support for positively impacting crop performance. The book will not be written in specialized, detail language but offer access for those with a wide range of interests in options for increasing crop production in the future. The goal of the book is to provide information that is useful to those with interests ranging from climatologist to food-oriented sociologists. Of course, the topics covered will be of direct interest to those studying plant sciences, particularly crop scientists. The hope is to challenge a reader to re-examine some of her/his assumptions about crop improvement and approach the topic with a renewed practice of skepticism in formulating and evaluating hypotheses.

Download or read book Advances in Environmental Stress Biology and Important Agronomic Traits Improvement in Non staple Crops written by Meng Kou and published by Frontiers Media SA. This book was released on 2024-05-15 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-staple crops (sometimes known as underutilized, semidomesticated, orphan and/or forgotten crops) usually refer to under-researched grain and legume compared to staple crops, such as sweetpotato, buckwheat, millet, barley, pea, mung beans, and adzuki beans, which contain unique and beneficial nutrients that staple crops do not have. Combining them with staple foods is an important guarantee for a nutrition-balanced diet. With the deepening of research, the current research on non-staple crops has gradually started to create a wide range of materials, identify varieties and quality, improve yield, respond to environmental conditions and regulate growth and development. Therefore, it is an important research objective to improve the important agronomic traits of non-staple crops, including anthocyanins in sweetpotato, rutin in buckwheat, vitamins in millet, β-glucan in barley, etc. through both cultivation and molecular breeding methods and to create new germplasm resources with high yield and abundant nutrients. Recently, notable successes have been made using genomic-related approaches to uncover the genes responsible for important phenotypes in non-staple crops. The genetic basis of metabolomic divergence and domestication has been revealed in buckwheat, and the QTLs for controlling agronomic traits such as flesh color of sweetpotato have been obtained, however the function of related genes still needs further investigation. In addition, biotic and abiotic stresses in extreme climatic conditions change the yield and quality of crops by affecting the growth and development of crops and important metabolic regulation processes. Non-staple crops are often climate-resilient and grown in marginal regions with low-input conditions, including examples for tolerance of drought stress in cowpea and buckwheat, tolerance of heat in cassava and tolerance of barren in sweetpotato. Investigating the mechanism of their environmental adaptability would provide new insights for breeding of not only non-staple crops but also staple crops that are limited in the tolerance of a changing climate to ensure future food security. It is of great theoretical significance and practical application value to study the molecular regulatory network of non-staple crops under these stress conditions. • Using cultivation measures, plant growth regulators, fertilizers, and other methods to improve the environmental stress resistance and important agronomic traits in non-staple crops. • Revealing molecular mechanisms and regulatory network under all kinds of environmental stresses in non-major crops and improving stress tolerance through genetic engineering. • Identifying key regulatory genes of important agronomic traits in non- staple crops and improving molecular breeding methods.

This book was released on 2019-07-01 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abiotic stresses like drought, temperature, cold, salinity, heavy metals etc. affect a great deal on the yield performance of the agricultural crops. To cope up with these challenges, plant breeding programs world-wide are focussing on the development of stress tolerant varieties in all crop species. Significant genomic advances have been made for abiotic stress tolerance in various crop species in terms of availability of molecular markers, QTL mapping, genome-wide association studies (GWAS), genomic selection (GS) strategies, and transcriptome profiling. The broad-range of articles involving genomics and breeding approaches deepens our existing knowledge about complex traits. The chapters are written by authorities in their respective fields. This book provides comprehensive and consolidated account on the applications of the most recent findings and the progress made in genomics assisted breeding for tolerance to abiotic stresses in many important major crop species with a focus on applications of modern strategies for sustainable agriculture. The book is especially intended for students, molecular breeders and scientists working on the genomics-assisted genetic improvement of crop species for abiotic stress tolerance.
Download or read book Deficit Irrigation Practices written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2002 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.
