Field experiment was carried out during 2020-2021 to study the effect of amino acids and silicon on flowering, fruit characters yield pomegranate cv. Phule Bhagwa Super in a randomized block design with seven treatments which were replicated three times. The Potassium silicate 0.5% (T1), 1.0 % (T2), Amino 150 ppm (T3), 200ppm (T4), 250 (T5), Water spray (T6), Absolute control (T7). Foliar spray...

potassium is an essential plant macronutrient. various microorganisms including bacteria and fungi, algae, yeast and mosses are able to decompose silicate minerals and to dissolve nutrient such as k, fe, zn and si. aamong them bacteria are more important. the aim of this study was to determine the ability of microbial populations for releasing soil potassium. this study was carried out as a fac...

Well-ordered mesoporous silicate films were prepared by infusion and selective condensation of silicon alkoxides within microphase-separated block copolymer templates dilated with supercritical carbon dioxide. Confinement of metal oxide deposition to specific subdomains of the preorganized template yields high-fidelity, three-dimensional replication of the copolymer morphology, enabling the pre...

Phytoliths are formed from silica carried up groundwater and some plants. The weathering of silicate minerals at the Earth’s surface provides large amounts soluble silica, which is absorbed by growing In solution, exists as mono silicic acid Si (OH4) with pH values 2–9. It upward in vascular system becomes concentrated during transpiration around leaf stomata. supersaturated solution begins to ...

It is a well-known fact that the spectra of oxygen-rich circumstellar dust envelopes around evolved stars show great diversity, especially in the 10 μm silicate band profiles, but also in the longer infrared wavelength range covered by ISO. This supports earlier conclusions that the concept of a universal cosmic silicate is inadequate and that it is reasonable to consider a wider variety of pos...

The existence of ether or ester-like complexes of silicate with organic compounds has long been debated in the literature on biological utilization of silicon. Comparison of theoretically calculated Si NMR chemical shifts for such complexes with experimentally measured values in biological systems could provide a diagnostic tool for identifying which, if any of these molecules exist under physi...

The function(s) of soluble silicates in repulpinghashing and flotation deinking of waste newsprint/magazine were investigated extensively, under optimized conditions. During repulping/washing, silicate ’s response was characteristic of a buffer and a detergent. It was responsible for a 3.0% increase in I S 0 brightness. In repulping/flotation, silicate accounted for a 6.1% increase in I S 0 bri...

Despite considerable work on other trace elements, the incorporation of dissolved silicon from cave waters into speleothems has not been previously investigated. In this study, the controls on dissolved Si in cave waters and on adsorbed Si in resulting speleothems are therefore investigated. Bedrock (dolomite), soil water, dripping water, and cave carbonates were retrieved from Heshang Cave sit...

this study was aimed to assess of priming effects on soluble proteins and antioxidant enzymes of as a nigella sativa medicinal plant under different levels of salinity and drought. two greenhouse factorial experiments with three replicated randomized complete block design were conducted.treatments included five levels of priming (potassium nitrate 1% and salicylic acid 0.2 mm in 6 hours, potass...

The view that silicon in animal tissues occurs in combination with organic groups has appeared repeatedly in the literature. As early as 1897 Drechsel & Winogradow described the extraction from goose feathers of an orthosilicate of the formula Si(OCuH5,90)4, stated to be an ester of a dihydric alcohol homologous with cholesterol. Isaacs (1924) inferred the presence of silicolipins in brain. Hol...
