Book excerpt: Excerpt from The Behavior of Stomata This investigation was undertaken to discover what changes take place in the apertures of stomata throughout the day and night, the in uence of physical factors upon such changes, and the final effect upon 'transpiration. Hence the investigation falls naturally into three subdivisions which form the sections of this volume. As previous investigators have usually worked with few plants and in one region, it was felt that considerable light could be thrown upon the subject by using many plants and working in several regions of diverse climate. Experiments which were first carried out at the American Smelting and Refining Company's laboratory near Salt Lake City were therefore continued at the Desert Laboratory at Tucson, Arizona, and at the University of Minnesota, Minneapolis, Minnesota, as well as at Salt Lake City. A wide range of climate was thus available, since the spring climate of Minneapolis is rather humid, the summer climate of Salt Lake City dry and sometimes hot, and the winter in Tucson dry and warm. For a number of reasons, most of the experiments were made at the Salt Lake laboratory, where the water-content could be controlled readily and the range of humidity and temperature from day to day was almost as great as in the desert. At the outset, careful consideration was given the methods hitherto employed to determine changes in stomatal apertures. The horn and yucca hygroscopes used by Darwin (1898) were properly criticized by Lloyd (1908) as measures of transpiration rather than Of the condition of the stomata. Cobalt-chloride paper is open to the same Objection, and therefore only indirectly throws light upon the opening of the stomata. Petroleum ether, when dropped upon a leaf, passes through it if the stomata are open and some times gives it a water-soaked, translucent appearance. Hence this reagent may be used as a qualitative test for stomatal opening. These methods, however, are no longer in use, and this left but three methods to be considered for the purpose Of the investigation.

Available in PDF, EPUB and Kindle. Book excerpt: Plants are subjected to a variety of abiotic stresses such as drought, temperature, salinity, air pollution, heavy metals, UV radiations, etc. To survive under these harsh conditions plants are equipped with different resistance mechanisms which vary from species to species. Due to the environmental fluctuations agricultural and horticultural crops are often exposed to different environmental stresses leading to decreased yield and problems in the growth and development of the crops. Drought stress has been found to decrease the yield to an alarming rate of some important crops throughout the globe. During last few decades, lots of physiological and molecular works have been conducted under water stress in crop plants. Water Stress and Crop Plants: A Sustainable Approach presents an up-to-date in-depth coverage of drought and flooding stress in plants, including the types, causes and consequences on plant growth and development. It discusses the physiobiochemical, molecular and omic approaches, and responses of crop plants towards water stress. Topics include nutritional stress, oxidative stress, hormonal regulation, transgenic approaches, mitigation of water stress, approaches to sustainability, and modern tools and techniques to alleviate the water stress on crop yields. This practical book offers pragmatic guidance for scientists and researchers in plant biology, and agribusinesses and biotechnology companies dealing with agronomy and environment, to mitigate the negative effects of stress and improve yield under stress. The broad coverage also makes this a valuable guide enabling students to understand the physiological, biochemical, and molecular mechanisms of environmental stress in plants.

Download or read book Physiology and Behaviour of Plants written by Peter Scott and published by John Wiley & Sons. This book was released on 2013-04-29 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiology and Behaviour of Plants looks at plants and how they sense and respond to their environment. It takes the traditional plant physiology book into a new dimension by demonstrating how the biochemical observations underlie the behaviour of the plant. In many ways the book parallels courses studied at university on animal physiology and behaviour. The plant has to meet the same challenges as an animal to survive, but overcomes these challenges in very different ways. Students learn to think of plants not only as dynamic organisms, but aggressive, territorial organisms capable of long-range communication. Hallmark features include: Based on a successful course that the author has run for several years at Sussex University, UK Relates plant biochemistry to plant function Printed in four colour throughout Includes a wealth of illustrations and photographs that engages the reader's attention and reinforce key concepts explored within the text Presents material in a modern 'topic' based approach, with many relevant and exciting examples to inspire the student An accompanying web site will include teaching supplements This innovative textbook is the ultimate resource for all students in biology, horticulture, forestry and agriculture.

Download or read book Photosynthesis Respiration and Climate Change written by Katie M. Becklin and published by Springer Nature. This book was released on 2021-05-31 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in atmospheric carbon dioxide concentrations and global climate conditions have altered photosynthesis and plant respiration across both geologic and contemporary time scales. Understanding climate change effects on plant carbon dynamics is critical for predicting plant responses to future growing conditions. Furthermore, demand for biofuel, fibre and food production is rapidly increasing with the ever-expanding global human population, and our ability to meet these demands is exacerbated by climate change. This volume integrates physiological, ecological, and evolutionary perspectives on photosynthesis and respiration responses to climate change. We explore this topic in the context of modeling plant responses to climate, including physiological mechanisms that constrain carbon assimilation and the potential for plants to acclimate to rising carbon dioxide concentration, warming temperatures and drought. Additional chapters contrast climate change responses in natural and agricultural ecosystems, where differences in climate sensitivity between different photosynthetic pathways can influence community and ecosystem processes. Evolutionary studies over past and current time scales provide further insight into evolutionary changes in photosynthetic traits, the emergence of novel plant strategies, and the potential for rapid evolutionary responses to future climate conditions. Finally, we discuss novel approaches to engineering photosynthesis and photorespiration to improve plant productivity for the future. The overall goals for this volume are to highlight recent advances in photosynthesis and respiration research, and to identify key challenges to understanding and scaling plant physiological responses to climate change. The integrated perspectives and broad scope of research make this volume an excellent resource for both students and researchers in many areas of plant science, including plant physiology, ecology, evolution, climate change, and biotechnology. For this volume, 37 experts contributed chapters that span modeling, empirical, and applied research on photosynthesis and respiration responses to climate change. Authors represent the following seven countries: Australia (6); Canada (9), England (5), Germany (2), Spain (3), and the United States (12).
Download or read book Abiotic Stress in Plants written by Arun Shanker and published by BoD – Books on Demand. This book was released on 2011-09-22 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: World population is growing at an alarming rate and is anticipated to reach about six billion by the end of year 2050. On the other hand, agricultural productivity is not increasing at a required rate to keep up with the food demand. The reasons for this are water shortages, depleting soil fertility and mainly various abiotic stresses. The fast pace at which developments and novel findings that are recently taking place in the cutting edge areas of molecular biology and basic genetics, have reinforced and augmented the efficiency of science outputs in dealing with plant abiotic stresses. In depth understanding of the stresses and their effects on plants is of paramount importance to evolve effective strategies to counter them. This book is broadly dived into sections on the stresses, their mechanisms and tolerance, genetics and adaptation, and focuses on the mechanic aspects in addition to touching some adaptation features. The chief objective of the book hence is to deliver state of the art information for comprehending the nature of abiotic stress in plants. We attempted here to present a judicious mixture of outlooks in order to interest workers in all areas of plant sciences.
