Available in PDF, EPUB and Kindle. Book excerpt: Abiotic stresses caused by drought, salinity, toxic metals, temperature extremes, and nutrient poor soils are among the major constraints to plant growth and crop production worldwide. While crop breeding strategies to improve yields have progressed, a better understanding of the genetic and biological mechanisms underpinning stress adaptation is needed. Genes For Plant Abiotic Stress presents the latest research on recently examined genes and alleles and guides discussion of the genetic and physiological determinants that will be important for crop improvement in the future.

Download or read book The Complete Guide to Restoring Your Soil written by Dale Strickler and published by Storey Publishing, LLC. This book was released on 2021-10-26 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthy soil is key to sustaining life on Earth. While more and more people are starting to see the need for soil restoration, there is very little understanding of just how it can be accomplished. There is a rapidly emerging demand for a “how to” manual for soil restoration. Dale Strickler is an expert on building healthy soil and restoring degraded soil, and in The Complete Guide to Restoring Your Soil, he presents the science of soil, along with proven methods of restoring depleted soil and agricultural practices from around the world that continue to build soil, rather than cause it to deteriorate. Strickler provides a solid foundation in the science of healthy soil, explaining how soil has become so degraded over time and the dire consequences for the human species, not just in terms of food scarcity but also the social, health, and environmental consequences of growing food in poor soil. He addresses the chemical, physical, and biological principles behind soil function, and presents actual farming practices that can be used to regenerate soil, techniques and strategies for remediating contaminated soil, and agriculture systems both past and present that functioned to build soil, such as the ancient chinampas systems of Mexico and the permaculture systems of today.

Download or read book The Biology and Utilization of Grasses written by V Younger and published by Elsevier. This book was released on 2012-12-02 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology and Utilization of Grasses reviews current knowledge about grass biology, and it highlights the important role of grasses in human existence. It discusses many fundamental aspects of grass biology, including evolution and genetics, morphology, physiology, and ecology, with emphasis on the relationship of these basic concepts to the use of grasses for forage, turf, and rangelands. Comprised of 28 chapters, this volume begins with an overview of the evolution and genetics of the grass family, followed by a discussion on practical grass-breeding problems. The reader is also introduced to vegetative growth and development of seedlings and mature plants; the ecological aspects of grasses; soils and mineral nutrition in relation to grass growth; the effects of defoliation (moving or grazing); carbohydrate reserves; physiology of flowering; and grass seed production and culture treatments. Other chapters consider the role of polyploidy in the evolution and distribution of grasses; selection and breeding of grasses for forage and other uses; seedling vigor and seedling establishment; environmental modification for seedling establishment; the microclimate of grass communities; effects on turf grass of cultural practices in relation to microclimate; and competition within the grass community. This book will be of benefit to plant breeders, ecologists, botanists, and biologists.

Download or read book Physiological Ecology of North American Plant Communities written by Brain F. Chabot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.
