Book Synopsis Effect of Seed Protein Content on Plant Growth of Barley and Wheat by : Arturo Lopez
Download or read book Effect of Seed Protein Content on Plant Growth of Barley and Wheat written by Arturo Lopez and published by . This book was released on 1972 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to evaluate the effect of seed protein content on plant growth of barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.). The effects of nitrogen application on chemical and morphological characteristics of the seed were also studied. Seeds of 'Casbon' winter barley and 'Nugaines' winter wheat with different protein content were obtained by field applications of various amounts of nitrogen at seeding time (fall) and tillering time (spring). The increase in protein content from high nitrogen rates was accompanied by a decrease in seed size and yield. The protein increase occurred primarily in the endosperm. Neither protein content nor size of the embryo was affected by rates of nitrogen application. The effect of seed protein content on plant growth was evaluated in terms of inhibition and respiration, speed of germination and subsequent seedling growth, root and shoot elongation at 15, 20 and 25C, and dry matter production when grown in low and high nitrogen soils in the green house. A positive relationship was found between seed protein content and plant performance. The rates of water absorption and oxygen consumption of germinating barley and wheat seed increased as a result of high protein content. High protein seed had a faster speed of germination and developed into larger seedlings with a higher dry matter content when grown in nitrogen-deficient soil. In nitrogen-enriched soil, seed protein content had little effect on seedling growth. The beneficial effects of seed protein content are more clearly expressed under stress conditions and are more evident when plant growth depends on the nutrients available from the seed. During initiation of germination, temperature influences the expression of the protein effect. After the seedling has formed and is capable of photosynthesis, the nitrogen availability in the soil influences the effect of seed protein content on plant growth. The relationship between seed protein content and plant growth can be an important factor in crop production because the increase in protein can be controlled by field application of nitrogen. However, since the high rates of nitrogen necessary to produce high seed protein levels are not consistent with the optimum nitrogen rates for yield, growers would probably be reluctant to apply such high rates unless some type of incentive were given them to do so. For seed production, it could still be important to strive for high protein levels in spite of some loss in yield if improved performance from high protein seeds proves to be of economic value. The results of this study indicate that producing and planting seeds rich in protein may be an effective method of achieving faster stand establishment of cereal crops. Additional research will determine the effects of high protein on yield.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the process of seed germination, antioxidant metabolism in barley seeds is intensified. Production of reactive oxygen and nitrogen species, and activities of enzymes scavenging these reactive species such as ascorbate peroxidase, monodehydroascorbate reductase, dehydroascorbate reductase, glutathione reductase, catalase, superoxide dismutase and S-nitrosoglutathione reductase, increased in germinating barley seeds instead of non-germinated more dormant Sundre seeds. Meanwhile the content of total ascorbate and glutathione and the rate of fermentation dropped in germinating seeds. Sharp decrease in glutathione content in embryos of barley seeds led to a dramatic increase in reduction potential of glutathione disulfide/glutathione couple. High levels of adenosine triphosphate and adenosine diphosphate were observed during the first few hours of germination but later their content decreased with a concomitant increase in their ratio in germinating seeds. Expression of the gene encoding alcohol dehydrogenase III declined in Harrington seeds from the onset of germination, while expression of the gene encoding hemoglobin was elevated within the first few hours and later declined, and the expression of the both genes did not change significantly in Sundre seeds. In the process of further transition from imbibition of dry Harrington seeds to seedling growth, glyoxylate cycle and citric acid cycle in scutellum became more active in the first few days, as evidenced by the increased activities of isocitrate lyase and malate synthase in glyoxylate cycle and succinate dehydrogenase and fumarase in citric acid cycle. During this period, the content of malic acid, succinic acid, and overall pH value declined in both scutellum and endosperm of Harrington seeds. In the endosperm, the content of succinic acid was much lower than malic acid and citric acid. The level of citric acid in scutellum was high and maintained stable while its level in endosperm was low. The increase of H2O2 production was observed during the process of seed germination and early period of seedling growth. In summary, the antioxidant metabolism, metabolism of reactive oxygen and nitrogen species, glyoxylate cycle and citric acid cycle were found to be more active during seed germination and early period of seedling growth.

Download or read book Biotechnological Applications of Seaweeds written by Elhafid Nabti and published by Nova Science Publishers. This book was released on 2017 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seaweeds, or marine macro-algae, are known as plants growing on the seashore, in salt marshes, in brackish waters, or in the ocean. Many species of seaweeds have shown an important utilization for the improvement of plant growth since ancient times, and this positive impact is due to their richness in diverse compounds like lipids, proteins, phyto-hormones, amino acids, antimicrobial compounds and different minerals. Other aspects of various seaweed application had been developed more recently for plant growth and health stimulation: seed germination improvement, shoot and root development, increase in water and nutrient uptake/resistance, phytoremediation and elimination of contaminated soil, and fertilization. Additionally, the use of marine algae is not limited to agriculture, and it also applies to the pharmaceutical industry (drugs) and other cosmetics. It is well documented that seaweeds are widely used as a source of food in many countries. It is very important to underline that the biotechnological utilization of seaweeds becomes undeniable in our time, because their richness and diversity can provide humans and animals a continuous food source devoid of pollutants, unlike chemical substances destroying the environment. For this reason, many experiments and reports concerning the diversity, ecology, chemical composition, function and other diverse characteristics of seaweed were carried out, and scientists still continue to investigate the impact this type of aquatic plant has on life on Earth.

Available in PDF, EPUB and Kindle. Book excerpt: A rapid, simple, and cost-effective testing procedure is described for determining the potential of a chemical to affect germination and early growth of terrestrial plants. Radish (Raphanus sativus L. var. Champion 708), lettuce (Lactuca sativa L. var. 525 Ithaca M.T.O.), and perennial ryegrass (Lolium perenne L. var. Manhattan) are routinely used in this test because of their economic and ecological importance, quick and high rate of germination, and relatively uniform root and hypocotyl/coleoptile growth. Plants are exposed to the chemical for seven days, after which germination, root length, and plant height values are determined. Average values for treated plants are compared with the corresponding values for the control (untreated) plants. An observed ratio (treated versus control means) of

This book was released on 2021-06-23 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biostimulants for crops from seed germination to plant development focuses on the effects and roles of natural biostimulants in every aspect of plant growth development to reduce the use of harmful chemical fertilizers and pesticides. Biostimulants are a group of substances of natural origin that offer a potential to reduce the dependency on harmful chemical fertilizers causing environmental degradation. While there is extensive literature on biostimulants, there remains a gap in understanding how natural biostimulants work and their practical application. This book fills that gap, presenting the ways in which biostimulants enhance seed vigor and plant productivity by looking into their mode of action, an area still being researched for deeper understanding. Exploring the roles of seed germination, pollen tube formation, pollen-pistil interaction, flower and fruit setting, to plant pigments, rhizospheric and soil microorganisms, the book also sheds light on the challenges and realistic opportunities for the use of natural biostimulants. Approaches biostimulant research with the goal of transforming scientific research into practical application Includes real-world examples from laboratory, greenhouse and field experiments Presents the biochemical, physiological and molecular mode of action of biostimulants
