Download or read book Nitrate Uptake by Red Maple Varies with Root zone Temperature written by Michael L. Adam and published by . This book was released on 2000 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrient uptake is a complex process influenced by plant factors, the growing medium, and interactions between the two. Mathematical models allow researchers to examine, isolate, and manipulate factors that impact uptake. To date, modeling efforts have not assessed the potential impacts of root-zone temperature on nutrient uptake kinetics. Our main objective was to determine the influence of root-zone temperature on nitrate uptake kinetics using solution-grown 'Autumn Flame' and 'Franksred' (Red Sunset[Registered trademark symbol]) ramets as representatives of red maple (Acer rubrum L.). We chose red maple because it is an important forest and landscaping species that occurs in a range of habitats over much of eastern North America. Our secondary objective was to examine the viability of using a modified soil method for determining nitrate uptake kinetics in the greenhouse.

Download or read book Environmental Adaptations and Stress Tolerance of Plants in the Era of Climate Change written by Parvaiz Ahmad and published by Springer Science & Business Media. This book was released on 2011-12-02 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is a complex phenomenon with a wide range of impacts on the environment. Biotic and abiotic stress are a result of climate change. Abiotic stress is caused by primary and secondary stresses which are an impediment to plant productivity. Prolonged exposure to these stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to withstand these stresses, e.g. synthesis of osmolytes, osmoprotectants, and antioxidants. Stress responsive genes and gene products including expressed proteins are implicated in conferring tolerance to the plant. This volume will provide the reader with a wide spectrum of information, including vital references. It also provides information as to how phytoconstituents, hormones and plant associated microbes help the plants to tolerate the stress. This volume also highlights the use of plant resources for ameliorating soil contaminants such as heavy metals. Dr. Parvaiz is Assistant professor in Botany at A.S. College, Srinagar, Jammu and Kashmir, India. He has completed his post-graduation in Botany in 2000 from Jamia Hamdard New Delhi India. After his Ph.D from the Indian Institute of Technology (IIT) Delhi, India in 2007 he joined the International Centre for Genetic Engineering and Biotechnology, New Delhi. He has published more than 20 research papers in peer reviewed journals and 4 book chapters. He has also edited a volume which is in press with Studium Press Pvt. India Ltd., New Delhi, India. Dr. Parvaiz is actively engaged in studying the molecular and physio-biochemical responses of different plants (mulberry, pea, Indian mustard) under environmental stress. Prof. M.N.V. Prasad is a Professor in the Department of Plant Sciences at the University of Hyderabad, India. He received B.Sc. (1973) and M.Sc. (1975) degrees from Andhra University, India, and the Ph.D. degree (1979) in botany from the University of Lucknow, India. Prasad had published 216 articles in peer reviewed journals and 82 book chapters and conference proceedings in the broad area of environmental botany and heavy metal stress in plants. He is the author, co-author, editor, or co-editor for eight books. He is the recipient of Pitamber Pant national Environment Fellowship of 2007 awarded by the Ministry of Environment and Forests, Government of India.

Download or read book Root Engineering written by Asunción Morte and published by Springer Science & Business Media. This book was released on 2014-04-12 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume illustrates the complex root system, including the various essential roles of roots as well as their interaction with diverse microorganisms localized in or near the root system. Following initial chapters describing the anatomy and architecture as well as the growth and development of root systems, subsequent chapters focus on the various types of root symbiosis with bacteria and fungi in the rhizosphere. A third section covers the physiological strategies of roots, such as nitrate assimilation, aquaporins, the role of roots in plant defense responses and in response to droughts and salinity changes. The book’s final chapters discuss the prospects of applied engineering of roots, i.e., inventing new root structures or functions through genetic modification, but also with conventional breeding and manipulation of root symbionts. The budding field of root engineering is expected to promote a second green revolution.

Available in PDF, EPUB and Kindle. Book excerpt: This assessment provides input to the reauthorized National Integrated Drought Information System (NIDIS) and the National Climate Assessment (NCA), and it establishes the scientific foundation needed to manage for drought resilience and adaptation. Focal areas include drought characterization; drought impacts on forest processes and disturbances such as insect outbreaks and wildfire; and consequences for forest and rangeland values. Drought can be a severe natural disaster with substantial social and economic consequences. Drought becomes most obvious when large-scale changes are observed; however, even moderate drought can have long-lasting impacts on the structure and function of forests and rangelands without these obvious large-scale changes. Large, stand-level impacts of drought are already underway in the West, but all U.S. forests are vulnerable to drought. Drought-associated forest disturbances are expected to increase with climatic change. Management actions can either mitigate or exacerbate the effects of drought. A first principal for increasing resilience and adaptation is to avoid management actions that exacerbate the effects of current or future drought. Options to mitigate drought include altering structural or functional components of vegetation, minimizing drought-mediated disturbance such as wildfire or insect outbreaks, and managing for reliable flow of water.
