";s:4:"text";s:19006:"Seeds soaked overnight in a liquid Silixol (diluted at 0.1 % or 0.2 %) solution exhibited a similar response in terms of seedling vigour and biomass. Both experimental designs were randomized blocks with treatments arranged in a 4 × 5 factorial scheme, with four Si sources: nanosilica (Si-nano), monosilicic acid stabilized with PEG-400 (Si-acid), sodium and potassium silicate stabilized with sorbitol (Si-alkali) and potassium silicate (Si-K) in five concentrations (0, 0.25, 0.5, 0.75 and 1.0 mmol L−1), and 4 repetitions. Three experiments were carried out: one with the cultivar Agata and another with Atlantic, in Botucatu, SP, Brazil; and one with the cultivar Agata, in Itaí, SP. Sulfuric acid is petitioned to be used for the same function (i.e., pH adjustment) in the 136 production of seaweed extracts, specifically fucoidans (Marinova, 2010). Based on patented production processes stabilized, plant available and plant active silicic acid is now used in agriculture-the silicic acid agro technology (SAAT). Silicon (Si) is the most abundant element present in the Earth's crust besides oxygen. The value of LER was not related to the concentration of P in leaves or shoots. Role of Orthosilicic Acid (OSA) Based Formulation, Received: 19 January 2015 / Accepted: 27 October 2015, © Springer Science+Business Media Dordrecht 2016. orthosilicic acid (OSA) in improving seedling development. However, Cu excess is harmful to plants. Increasing blue light often inhibits cell division, cell expansion, and thus reduces leaf area. Characteristics of an acceptable silicon (Si) source are: a high content of soluble-Si, physical properties conducive to mechanized application, ready availability, and low cost. A threefold increase in the seedling, length was recorded in the sprayed plants compared to the, In main fields, foliar sprays at three critical stages of, of tillers along with various yield attributing traits were. Arsenic (As), a toxic metalloid, is finding its route to human through intake of As-contaminated water and consumption of food grown on contaminated soil. PurposeLodging resistance in upland rice requires adequate knowledge of the mechanical basis of culm morphological traits (CMTs) with potential for improved structural integrity under orthosilicic acid (OSA) fertilizer. The SiO2 concenttration and/or amount per stem in bleeding sap was shown to be highly positively correlated with root respiration. A heat-map analysis of traits also commercialised for use in plant agriculture in the USA as early as 1955 (10, 15). Crown characteristics include; crown length, crown width, crown base height, crown closure and foliage. A yeast complementation assay suggested that the plasma membrane-localized AhYSL3.1 was a Cu-nicotianamine complex transporter. 2015; ... Si is also known to increase soil nutrient availability particularly P in plants and to maintain a balance between macro (N and P) and microelements such as zinc (Zn) and manganese (Mn) (White et al. In many plant species, foliar sSA applications increase the nutrient uptake as measured by yield (e.g., grain) and straw, the concentrations of N, P, K and Si in the flag leaves [68] and the concentrations of P, Ca and K in young rice plants, ... Overnight soaking of rice seeds in water with 0.1% sSA increases germination and root development significantly. Even highly purified water con-, tric charge and is not very mobile in plants [, 20 cm soil layer contains only an average of 0.1 to 1.6 kg Si, as well as aquaporins have been identified which in, uptake of silicic acid from soil and that its translocation to, been identified to be transported from roots to shoots via the, Monosilicic acid polymerizes to a Si gel when Si con-, centration increases in the plant water [, a very mobile element as well as being highly unstable in the, monomeric form in plants; therefore, a continuous supply. 2 % v/v) of Silixol (a proprietary formulation with stabilized orthosilicic acid 0.8 %) were used. Experimental results were integrated in a simulation model to study the relative importance of each process in determining the plant leaf area during vegetative stages of wheat. and crown characteristics. In 2003, foliar sprays with (stabilized) silicic acid were introduced, and more recently foliar sprays with silica nanoparticles have also been applied. Bending stress had the highest but negative significant correlation (-0.74**) with LRI.Conclusions recorded better in sprayed plants compared to the control. This study evaluates the effect of alternative Si sources applied via foliar spraying at lower concentrations in relation to potassium silicate, on Si accumulation and the beneficial effects on pre-sprouted sugarcane seedlings and initial growth. The results showed that the application of two silicon sources by foliar or root, with Major effects on cucumber leaves of added Si were: increased rigidity of the mature leaves which had a rougher texture and were held more horizontally; they were darker green and senescence was delayed. The solubility of soil Si is low. Sulfuric acid … In the initial growth of sugarcane, the sources Si-acid and S-alkali also increase the buildup and beneficial effects, but both sources at 0.6 mmol L−1 concentrations. The number of aphids and beetles detected on the leaves and the number of lesions caused by the beetles were evaluated. Silicon has been accepted worldwide as an important beneficial element required for the proper functioning of the plants particularly in cultivating crops.Plants can absorb silicon only in the form of Orthosilicic acid (OSA). In this work we use experimental and simulation techniques to identify and quantify these processes in wheat plants growing under P-deficient conditions. The presence of silica in pasture plants ensures that grazing ruminants ingest rather large amounts of silica, most of which is in the solid form. Consistent with our results, an increase in the content of N in gerbera (Gerbera jamesonii) (Savvas et al. Seeds were treated with Silixol in two ways: wet coating and overnight soaking. 34 acid explodes violently upon heating. The model simulates crown growth of an average tree. 1 SiNPs by root application to 60% for 200 mg L− The effect of P deficiency on LER was the main determinant of the final size of the individual leaves. Seedlings sprayed with Silixol had higher levels of chlorophyll content over the control, accounting for a higher rate of photosynthesis. To read the full-text of this research, you can request a copy directly from the authors. To date, very few studies have tested the health effects of orthosilicic acid. The maximum vanillin intake resulting from the consumption of OSA-VC would be less than 5% of the acceptable daily intake (ADI) value for vanillin of 10 mg/kg body weight (bw) per day established by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) in 2002. Of those, calcium meta-silicate (wollasonite, CaSiO3) has been the most effective source in many locations with low concentrations of soluble-Si in soils. Relationship between Root Respiration and Silica:Calcium Ratio and Ammonium Concentration in Bleeding Sap from Stem in Rice Plants during the Ripening Stage. Panel on Food Additives and Nutrient Sources Added to Food. Heart disease 5. The dissolved silica that is absorbed from the alimentary tract is carried to the kidney and excreted in the urine. Silicon has already been associated with bone mineralization, … Despite regular applications of fungicide, outbreaks of the fungal disease occurred on most of the mature leaves on the low Si plants, while the high Si plants remained almost completely free of symptoms. Seeds wet coated with Silixol exhibited good seedling vigour coupled with increased seedling length and biomass. In this search for a stable, high bioavailable form of Si, a number of molecules have been developed. Orthosilicic acid Monosilicic acid Tetrahydroxysilane Silicic acid (H4SiO4) Silicon tetrahydroxide More... Molecular Weight 96.11 g/mol Dates Modify 2021-02-13 Create 2004-09-16 Silicic acid is a silicon oxoacid. Two experiments were carried out in a greenhouse, one in the production phase of pre-sprouted seedlings and the other in the initial growth phase of sugarcane grown in pots. Application of Si, either in soil or on leaves (foliar), greatly reduced grain As accumulation (up to 67% in AsV and 78% in AsIII) and enhanced the growth and yield of plants under As stress. Addition of Si did not affect the final leaf area of the mature leaves but root fresh weight and dry weight were increased. Potato crops are susceptible to various insect pests including the aphid Myzus persicae (Hemiptera, Aphididae) and the beetle Diabrotica speciosa (Coleoptera, Chrysomelidae). Different concentrations (0.1 % or 0. Their concentrations and solubility of Si and their contents of other elements vary widely. Photosynthetic efficiency is measured as quantum yield: moles of carbon fixed per mole of photons absorbed. Si in soil solution (intensity factor) is largely influenced by its dissolution kinetics, which in turn is influenced by various soil factors such as Al, Fe oxides, organic matter, redox potential, and moisture. Using Genotype and Genotype × Environment (GGE) comparisons bi-plot, NERICAs 4,6,7,8 and Moroberekan compared well with NERICA 1 for LRI. OSA is water soluble and is the only biologically active form of silica. 1 can The thicker leaves have higher photosynthetic rates per unit area, but reduced radiation capture. Four experimental groups were studied, namely, plants cultivated in soil supplied with organic compost (30 t/ha) and either treated or non-treated with 0.5% silicic acid, and plants cultivated in soil supplied with NPK fertiliser (4:14:8; 4 t/ha) and either treated or non-treated with 0.5% silicic acid. However, the exact biological roles of silicon remain unknown. The treatments were foliar application of Si at a dosage of 2L ha-1 of Silamol ® (0.8% soluble Si as a stabilised concentrate of silicic acid) and a control (without the application of Si). Thus, Cu in plant tissues must be tightly regulated. Relative values of the tillering rate showed an hyperbolic relationship with the shoot P% saturating at values above 0.38%. The foliar spraying of Si on pre-sprouted sugarcane seedlings is feasible since it increased Si accumulation, and benefited seedling production and plant initial growth. Slags, by-products from the processing of iron and alloy industries, have been utilized quite extensively. Responses of crops to soluble-Si applications in sands (largely SiO2) provide an example of the insolubility of one source. Although it is normally excreted readily, the silica is sometimes deposited to form calculi or uroliths that can cause serious economic loss. A continues supply of this element provides a healthy and reproductive In this study, we found that the peanut Yellow Stripe-Like family gene AhYSL3.1 is involved in Cu transport. 1 Si and 400 mg L− Access scientific knowledge from anywhere. Contrary to these measurements, studies in whole plants have found that photosynthesis often increases with an increasing fraction of blue photons. Manufacturer of Silicic Acid - Orthosilicic Acid Powder offered by Axiogen Biotech, Chennai, Tamil Nadu. Seeds were treated with Silixol in two ways: wet coating and overnight soaking. Under extreme P-deficient conditions the simulation model failed to explain the experimental results indicating that other factors not taken into account by the model, i.e. Cucumber plants (Cucumis sativus) cv. application may have many advantageous effects. High cholesterol 6. At 20 days after heading, CMTs related to lodging were assessed among the rice cultivars.ResultsApplication of 500 and 750 ml ha− 1 of OSA gave the highest CMTs with reduced lumen diameter. Rice is the most As-affected crop. Si and synthesized silicon nanoparticles (SiNPs) on the morphological and biochemical properties, leaf nutrient content, and Volmann, causes substantial damage to the growth and development of Scots pine (Pinus sylvestris L.) stands. Therefore, the present research was conducted to investigate the effects of Safety of orthosilicic acid‐vanillin complex (OSA‐VC) as a novel food ingredient to be used in food supplements as a source of silicon and bioavailability of silicon from the source Panel members: Peter Aggett, Fernando Aguilar, Riccardo Crebelli, Birgit Dusemund, Metka Filipič, Maria Jose Frutos, Pierre Galtier, David Gott, Ursula Gundert‐Remy, Gunter Georg … … be recommend for improving the growth and flowering of tuberose plants, although the root application of Si at 200 mg L− Potassium silicate is used in nutriculture for disease control in some high value crops. Ten upland rice cultivars, comprising NERICAs 1 to 8, Moroberekan, and Ofada were grown on loamy-sand soil under four rates (0, 250, 500 and 750 ml ha− 1) of OSA. Present study is aimed to assess the impact of stabilized orthosilicic acid (a proprietary formulation for plant-available silicon (Si) and earlier used as fertilizer for rice to enhance growth and yield) in reducing the accumulation of As in rice grains. In recently expanded leaves phosphorus deficiency reduced the photosynthesis rate per unit leaf area at high radiation (AMAX), up to 57%. The average NH3 concentrtation in bleeding sap of shading plants was remarkably higher (8.3ppm) than those of other treatments and shading plants had shown the lowest content of total sugar in roots during ripening. 2015; ... Si was applied in the form of orthosilicic acid (OSA) either on leaves by using a liquid formulation with 0.4% OSA (foliar Si) or in the soil by using a granular formulation with 5% OSA (soil Si) provided by Privi Life Sciences Pvt. In contrast, solutions of peracetic acid used as sanitizers are created by 35 combining aqueous mixtures of two substances: acetic acid (the acid in vinegar) and hydrogen peroxide. Plants that have been sprayed with the PEG-400-stabilized monosilicic acid (Si-acid) and the sorbitol-stabilized sodium and potassium silicate (Si-alkali) at 0.5 and 0.6 mmol L−1 concentrations, respectively, promote had greater Si accumulation and beneficial effects in the growth of pre-sprouted sugarcane seedlings in production phase. Calcium silicates have emerged as the most important sources for soil applications. Different forms of Si may be used in fertigation, e.g. The toxicological data provided in support of the current application were not in accordance with the Tier 1 requirement of the ‘Guidance for submission for food additive evaluations’; however, this was considered justified by the Panel given that OSA-VC at pH 6.8 dissociates into orthosilicic acid and vanillin. Silicic acid only exists in two states, amorphous and crystalline. ... Foliar PEG-sSA increased growth parameters (root volume, number of tillers) and yield parameters significantly. Orthosilicic acid is a chemical compound with formula Si(OH) 4. 1 Silicon is present in beer in the soluble form of orthosilicic acid 4 in which form there is > 50% bioavailability. Plants take up different amounts of silica, according to their species. Rice plants were given various treatments, such as organic matter application, a large amount of nitrogen as topdressing and light shading of 75%, and ammonium (NH3), silica (SiO2) and calcium (Ca) in bleeding sap were then measured from young panicle formation to ripening stage. The need to characterize the CMTs of other NERICAs to establish LRI that confers susceptibility, moderate and high resistance to lodging was emphasized. vase life of tuberose (Polianthes tuberosa L.). from 32% for 200 mg L− In many trials since 2003 this stabilized SA has shown to be very effective on almost any plant. Si and SiNPs were applied at 200 mg L− Based on patented production processes stabilized, plant available and plant active silicic acid is now used in agriculture: the silicic acid agro technology. Plants can absorb silicon only in the form of Orthosilicic acid (OSA). This chapter summarizes the past and current literature on Si nutrition of rice. Different concentrations (0.1 % or 0. All rights reserved. It allows plants to reach their full potential in yield, quality, growth and vigor. Therefore, it supported that the plants which had high root respiration realized to be higher SiO2 concentration in their leaves. photons. This blue-lightinduced reduction in photon capture is usually the primary reason for reduced growth in spite of increased photosynthesis per unit leaf area. This is due to several reasons like the instability of this molecule which polymerizes very fast. The SiO2 concentration in bleeding sap gradually decreased, essentially in parallel with root respiration, according to plant aging. A few sources are soluble, but too costly for general use. Relative values of AMAX showed an hyperbolic relationship with leaf P% saturating at 0.27%. A new study suggests that beer is a significant source of dietary silicon, a key ingredient for increasing bone mineral density. The doses of Si were selected on the basis of previous studies using Silixol as a rice crop booster (Jawahar et al. Crown width growth is regulated by the light it receives and the concurrent height increment. 2007), P in rice, ... Foliar application of fertilizer can improve nutrient absorption, the efficacy of fertilizer use and increase the growth of plant [32,33]. Soil solution is the immediate source of the silica that is always absorbed by soil-grown plants. Arsenic exposure constrained some of the trace elements, such as Zn and Co, which were restored by Si application. they had shorter petioles and an increased fresh weight per unit area, dry weight per unit area, chlorophyll content, RuBPcarboxylase activity and soluble protein (all expressed per unit area of interveinal laminar tissue). Alzheimer's disease 2. NERICA cultivars with lower LRI will be more desirable to minimize lodging at moderate rate(s) of foliar OSA fertilizer. Seeds soaked, overnight in a liquid Silixol (diluted at 0.1 % or 0.2 %) solu-, tion exhibited a similar response in terms of seedling vigour, and biomass. OSA fertilizer can improve lodging resistance through increased culm wall thickness and reduced lumen diameter in resistant cultivars such as Moroberekan and NERICA 4. These transgenic plants were resistant to excess Cu. This paper presents a dynamic tree growth model that quantifies the effect of mistletoe on the growth and development of Scots pine. Similar approach was adopted to calculate diameter growth. Content courtesy of Springer Nature, terms of use apply. Key Words: Viscum album, Pinus sylvestris, Growth, Model.
