This book was released on 2018 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperature is a major factor affecting plant growth and development at all stages. The objectives of this study were to investigate the temperature effects on all aspects of soybean growth and development. Five experiments were conducted at a wide range of temperatures under optimum water and nutrient conditions at specific growth stages. Two cultivars, Asgrow AG5332 (AG) and Progeny P5333RY (PR) from MG V with different growth habits, were used. All studies except the seed germination were conducted in sunlit plant growth chambers under optimum water and nutrient conditions. The seed germination experiment was conducted in a temperature-controlled incubator. Germination traits were measured during seed germination studies. In other experiments, plant growth, developmental rates, gas exchange parameters, and seed yield and quality were measured. Cultivars did not differ for seed germination and emergence traits. Quadratic functions best described time to 50% germination seed germination and emergence rates. The three cardinal temperatures for seed germination were 8.56°C (base) 27. 96°C (optimum) and 46.92°C (maximum). The base and optimum temperature for seed emergence were 10.6 and 36.7°C, respectively. During the early-season, 0-21 days, root and shoot growth parameters responded similar temperature responses, the root traits have a lower optimum (29.91°C) than the shoot parameters (36.56°C). Cultivars varied in their response to temperature during vegetative development, particularly for growth parameters, and the temperature optimums for various parameters. Node addition rate was not different among the cultivars but increased with increase in temperature. The flowering time (R1) from emergence showed quadratic trends with an increase in temperature up to 28°C and increased slightly at the higher temperatures. The PR cultivar, on an average, took 15 additional days to reach flowering compared AG cultivar across temperatures. Pod and seed yield and individual seed weight and harvest indices showed quadratic trends with maximum values at 25.82 °C for AG and 23.36 °C for PR. The functional algorithms could be helpful for management and in improving crop models..

Download or read book Soil Moisture Stress Effects on Soybean Vegetative Physiological and Reproductive Growth and Post harvest Seed Physiology Quality and Chemical Composition written by Chathurika Wijewardana and published by . This book was released on 2018 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing scarcity of water resources, soil moisture stress is the single most threat to global soybean production causing extensive yield losses. The objectives of this study were to investigate soil moisture stress effects on all aspects of soybean growth and development processes and to develop functional algorithms that could be used for field management decisions and in soybean crop modeling. To fulfill these objectives, six experiments were conducted; one in vitro osmotic stress study on seed germination, four studies by imposing five soil moisture treatments, 100, 80, 60, 40, and 20% of daily evapotranspiration of the control at different growth stages using sunlit plant growth chambers, and one transgenerational study on seed germination at different osmotic levels and offspring growth at three irrigation treatments (100, 66, and 33% based on field capacity) for plants grown at different soil moisture levels. Two cultivars from maturity group V, Asgrow AG5332 and Progeny P5333RY, with different growth habits were used in all these studies. Midday leaf water potential, plant height, mainstem nodes, gas-exchange traits, canopy reflectance, and several yield components including pod weight, seed yield, and seed quality were measured. Soil moisture stress decreased biomass, net photosynthesis, yield, individual seed weight, maximum seed germination, protein, fatty acids, sucrose, N, and P and increased oil, stachyose, Fe, Mg, Zn, Cu, and B contents. Overall, Asgrow AG5332 was more tolerant to drought stress than Progeny P5333RY. Soil moisture stress induced changes in seed quality that were correlated with seed germination and seedling vigor in the F1 generation. These data can be used to build a model-based decision support system capable of predicting yield under field conditions.

Download or read book Consequences and Mitigation Strategies of Heat Stress for Sustainability of Soybean Glycine Max L Merr Production Under the Changing Climate written by Ayman EL Sabagh and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing ambient temperature is a major climatic factor that negatively affects plant growth and development, and causes significant losses in soybean crop yield worldwide. Thus, high temperatures (HT) result in less seed germination, which leads to pathogenic infection, and decreases the economic yield of soybean. In addition, the efficiency of photosynthesis and transpiration of plants are affected by high temperatures, which have negative impact on the physio-biochemical process in the plant system, finally deteriorate the yield and quality of the affected crop. However, plants have several mechanisms of specific cellular detection of HT stress that help in the transduction of signals, producing the activation of transcription factors and genes to counteract the harmful effects caused by the stressful condition. Among the contributors to help the plant in re-establishing cellular homeostasis are the applications of organic stimulants (antioxidants, osmoprotectants, and hormones), which enhance the productivity and quality of soybean against HT stress. In this chapter, we summarized the physiological and biochemical mechanisms of soybean plants at various growth stages under HT. Furthermore, it also depicts the mitigation strategies to overcome the adverse effects of HT on soybean using exogenous applications of bioregulators. These studies intend to increase the understanding of exogenous biochemical compounds that could reduce the adverse effects of HT on the growth, yield, and quality of soybean.

Available in PDF, EPUB and Kindle. Book excerpt: Soybean Physiology, Agronomy, and Utilization attempts to cover and treat in logical sequence the factors that contribute to the potential and versatility of soybeans. The soybean is a major crop plant in the United States. Based on the utilization of the bean, or products therefrom, a substantial soybean industry has also developed. Its uses, agricultural and industrial, primarily depend on the high content of both protein (ca. 40%) and oil (ca. 20%) in the bean. The book begins by discussing soybean production in the United States and worldwide; the uses and economics of soybean products; and the soybean in physiological research. It explains the growth and development of soybeans. It discusses the physiological processes responsible for assimilating the plant body from the environment, namely photosynthesis, nitrogen fixation, and nitrate reduction. Subsequent chapters examine the impact of environmental variables—such as light, temperature, water, wind, and pests—on soybean plant characteristics as well as soybean breeding, production, processing, and utilization.
