Silicon, which is widely used in different fields, has been plant production vivo and vitro studies recent years. Especially studies, it seen that its effect on growth development examined. In this study, the of three silicon sources their four concentrations micro-propagation 140 Ru grape rootstocks was investigated. as explants one-node micro cuttings rootstock MS (Murashige Skoog) nutrient m...

Silicon (Si) is the second most abundant element in soils, and at elevated concentration levels in plant tissue Si is reported to improve plant resistance to a range of biotic and abiotic stresses. in the present study, Si solutions at 100, 300 or 500 mg l-1 made from potassium silicate (K2Sio3) were applied as foliar sprays or soil drenches to pepper (capsicum annum l.) plants, and their effec...

Abstract The influence of various ways using silicon in the form potassium silicate on yield spring wheat under conditions model agrocenosis has been studied. To address issues raised, a vegetative experiment was carried out soil culture. Studied two making by treating seeds before sowing and applying to soil. positive effect silicon-containing compound established both mass grain straw. greate...

During the 2019 and 2020 seasons, Sultani fig trees were sprayed two times (at 1st week of April May) with levels potassium silicates (1 2 %), Calcium nitrate %) kaolin at 5 %. The study focused on effect foliar application kaolin, silicon vegetative growth, tree nutritional status, number fruits per yield fruit quality.Results showed that applications 1% or 2% silicate, calcium 5% very effecti...

This research was conducted to evaluate effect of potassium and iron fertilizers on agro-physiological traits affected different irrigation regime of corn in Shahryar (Tehran province, central of Iran) via a split-split plots arrangement based on randomized complete blocks design with three replications during 2015. The main plot included different irrigation regime (Normal irrigation and stop ...

Introduction: Core formation processes in planets may impart stable isotope ratio signatures on the bulk silicate Earth due to partitioning between the metallic core and silicate [1]. Enstatite chondrites (E-chondrites) are the only primitive meteorite group with stable oxygen isotope compositions similar to Earth [2]. The Echondrites also possess a metal phase with substantial amounts of Si. W...

Integration of light sources on a Si chip is one of milestone to establish new paradigm of LSI systems, so-called “silicon photonics.” In recent years remarkable progress has been made in the Si wire waveguide technologies for optical interconnection on a Si chip. In this paper, several Er embedded materials based on silicon are surveyed from the standpoint of application to the light emission ...

A new method for growing silicon nanowires was presented. They were grown in an aqueous solution at a temperature of 85 oC under atmospheric pressure by using sodium methylsiliconate as a water‐soluble silicon precursor. The structure, morphology, and composition of the as‐grown nanowires were characterized by scanning electron microscopy, transmission electron microscopy, and en...

[1] We analyzed dSi of dissolved silicate for eight water column profiles across the Southern Ocean (south of Australia in spring 2001) from the Seasonal Ice Zone (SIZ) north to the Subantarctic Zone (SAZ), including the first isotopic compositions measured for Si-depleted seawaters. All profiles display mixed layer enrichments in heavy Si isotopes relative to deep water in accordance with pref...
