This book was released on 1975 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of growth of maize in relation to water in the soil-plant system was conducted in the field at Davis, California. The time course of root and aerial growth, and water uptake was investigated under conditions of a mild prolonged water stress, with emphasis of defining the soil and crop water status, photosynthesis and the generation of the yield and yield components also were studied. Hybrid maize was grown in deep alluvial soil with high mositure holding capacity. Three irrigation treatment were: a) Weekly 5-cm irrigation starting 21 days after planting (I treatment); b) No irrigation (NI treatment); c) Weekly 5-cm irrigation starting 55 days after planting (155 treatment). Shoot growth. NI treatment, compared to I treatment, reduced crop height 6.5% leaf area 11% although leaf y (water potential) generally was only 2 bars lower at midday during vegetative growth. Diunally, leaf elongation rate (in both treatment) was unespectedly fastest in early afternoon when leaf y was near the daily minimum. Leaf (solute potential) changes lagged behind y so high occurred at near minimum y values, and daytime elongation rates (presumably when temperature was not limiting) correlated with - leaf changes were associated with those of oraganic solutes; soluble leaf carbohydrates changes accounted for 40% of fluctuations. Consistently lower leaf elongation rates in NI treatment could m-not be explained by differences alone, however. Root growth water absorption. Water uptake at various soil depth and times (...).

Available in PDF, EPUB and Kindle. Book excerpt: Water stress and heat stress are considered to be two primary factors that limit crop production in many parts of the world. Global warming appears to be increasing the water requirements of plants. Understanding the impact of water deficit on plant physiological processes and efficient water management are of great concern in maintaining food production to meet ever increasing world food demand. The book addresses various climatic soil and plant factors that contribute to the water use efficiency in plants subjected to water stress. It covers all issues related to soil, plant and climatic factors that contribute to the crop responses to water stress. The books advances the knowledge in improving and sustaining crop yields in ever increasing unpredictable climatic fluctuations This book uses crop simulation models for response of crops to limited water under various management and climatic conditions.

Book excerpt: Maize is one of the versatile emerging crops with wider adaptability under varied agro-climatic conditions. Globally, maize is known as queen of cereals because it has the highest genetic yield potential among the cereals. It is cultivated on nearly 150 m/ha in about 160 countries having wider diversity of soil, climate, biodiversity and management practices that contributes 36 % (782 m/t) in the global grain production. The United States of America (USA) is the largest producer of maize contributes nearly 35 % of the total production in the world. It is the driver of the US economy. This book talks about the improvement, production, protection and post harvest technology of the maize crop.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on early germination, one of maize germplasm most important strategies for adapting to drought-induced stress. Some genotypes have the ability to adapt by either reducing water losses or by increasing water uptake. Drought tolerance is also an adaptive strategy that enables crop plants to maintain their normal physiological processes and deliver higher economical yield despite drought stress. Several processes are involved in conferring drought tolerance in maize: the accumulation of osmolytes or antioxidants, plant growth regulators, stress proteins and water channel proteins, transcription factors and signal transduction pathways. Drought is one of the most detrimental forms of abiotic stress around the world and seriously limits the productivity of agricultural crops. Maize, one of the leading cereal crops in the world, is sensitive to drought stress. Maize harvests are affected by drought stress at different growth stages in different regions. Numerous events in the life of maize crops can be affected by drought stress: germination potential, seedling growth, seedling stand establishment, overall growth and development, pollen and silk development, anthesis silking interval, pollination, and embryo, endosperm and kernel development. Though every maize genotype has the ability to avoid or withstand drought stress, there is a concrete need to improve the level of adaptability to drought stress to address the global issue of food security. The most common biological strategies for improving drought stress resistance include screening available maize germplasm for drought tolerance, conventional breeding strategies, and marker-assisted and genomic-assisted breeding and development of transgenic maize. As a comprehensive understanding of the effects of drought stress, adaptive strategies and potential breeding tools is the prerequisite for any sound breeding plan, this brief addresses these aspects.

Download or read book Hormonal Regulation of Development III written by Richard P. Pharis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: R. P. PHARIS and D. M. REID The idea of a separate Encydopedia volume dealing with the "interrelations of plant hormones with factors in the environment of the plant, and its organs and tissues" originated with N. P. KEFFORD, and we are most appreciative of the help and advice provided by Prof. KEFFORD in the formative stages of this volume. We have thus interpreted "environment" very broadly to indude not only factors external to the plant, e. g. , gravity, light, temperature, wind, mechanieal wounding, water, organism s (induding pollen), and magnetic and electric stimuli, but internaI factors as well (e. g. , nutrients, both inorganic and photoassimilate, direction, and time). In our definition of "hormonaI effect", or "hormonaI involvement", we have asked our authors to take a broad ap proach, and to examine not only phenomena that are mediated by the known plant hormones, but to discuss as well a wide variety of processes and events where hormonal involvement is implied through more indirect analyses and observations. The volume begins with environmental factors internaI to the plant; R. J. WEAVER and J. O. JOHNSON thus examine "hormones and nutrients", their inter relationship in movement, accumulation, and diversion. As one studies a plant during its rapid growth phase, and later as maturation and aging proceed, it becomes apparent that time is an environmental cue of great significance, one which may exert a major influence via hormonal messages.

Available in PDF, EPUB and Kindle. Book excerpt: Describes the basics of ROS metabolism in plants and examines the broad range of ROS signaling mechanisms New discoveries about the effects of reactive oxygen species (ROS) on plants have turned ROS from being considered a bane into a boon, because their roles have been discovered in many plant developmental processes as signaling molecules. This comprehensive book teaches about the role of ROS metabolism in plants and how they affect various developmental processes. It also discusses in detail the advancements made in understanding the ROS signaling. Reactive Oxygen Species in Plants: Boon Or Bane - Revisiting the Role of ROS begins by presenting the basic introduction to ROS and deciphers the detailed knowledge in ROS research. It then examines the broad range of ROS signaling mechanisms as well as how they may be beneficial for plants and human beings. This book also describes both the bane and boon aspects of ROS with their impact on plants, and how the recent revelations have compelled us to rethink ROS turning from stressors to plant regulators. ● Compiles, for the first time, the wholesome knowledge in ROS research and their cellular signaling ● Includes new discoveries and in-depth discussions about the advancements made in the field ● Discusses reactive oxygen species which are involved in a broad range of biological processes Reactive Oxygen Species in Plants: Boon Or Bane - Revisiting the Role of ROS will help scientists to utilize the functions of ROS signaling for plants and also enable readers to gain a deeper knowledge of ROS research and signaling. It is highly recommended for researchers, scientists, and academicians in plant science as well for advanced undergraduate and postgraduate students.
