Silicon is a quasi-essential trace nutrient for plant growth and frequently employed to remediate soils of heavy metal pollution in agriculture. However, silicon’s role mechanism reducing toxicity have not been well understood, especially multi-heavy metals such as cadmium, zinc, lead, arsenic (usually treated metal). In this study, the effects different silicon-rich materials (silicate, rice h...

Calcium ions react with silicic acid released from dissolving porous silicon nanoparticles to create an insoluble calcium silicate shell. The calcium silicate shell traps and protects an siRNA payload, which can be delivered to neuronal tissues in vitro or in vivo. Gene delivery is enhanced by the action of targeting and cell-penetrating peptides attached to the calcium silicate shell.

To decrease adverse effects of water deficit is foliar application with chemical agents such as silicon. However, there is low information on the influence of silicon on alfalfa under drought stress conditions. Thus, the current study was conducted to assessment the effect of different silicon concentrations (0, 1 and 2 mili Molar concentration) on alfalfa growth trend and biochemical traits, w...

The effect of potassium supply of Vicia faba on the fixation of molecular nitrogen by root nodules was studied by using (15)N-labeled molecular nitrogen. Plants well supplied with potassium showed higher contents of (15)N in the soluble amino fraction and in the protein fraction of various plant organs as compared with plants of a lower potassium status. This effect was evident particularly in ...

Abstract Wheat productivity is severely hampered by drought, owing to its negative impacts on crop growth and development. For obtaining better yield, the of drought should be ameliorated. Therefore, current study scrutinizes potential different silicon (Si) forms minify drought-associated reduction in yield changes nutrients accumulation. In a strip plots design based randomized complete block...

from the plants nutrition view point, silicon has not been recognized as an essential element but its useful effects on growth and development of many plants have been reported. in order to study the effect of application of different silicon on the yield component of wheat, an experiment was conducted in the city torbat heidarieh located in razavi khorasan province. the experiment was performe...

The detrimental drought effects could be listed as the loss in dry weight and silicon is known to enhance crop tolerance to drought by increasing seedling growth and hydraulic conductivity. To investigate the effects of silicon priming (0, 1 and 2 mM as sodium silicate), on seedling growth and root anatomy of three barley cultivars (Khatam, Rihane, and Nimrooz) a laboratory experiment was condu...

South African discard coal fines and K2CO3 blends were heated in a laboratory-scale rotary kiln to produce ashes for H2SO4 leaching tests. The optimized conditions of 6.12 mol.dm3 (M) H2SO4, solid liquid ratios 1:5 1:10, 8o°C 8 hours used. was added increase the dissolution efficiency K. objective determine if Al present metakaolinite (Al2O3.2SiO2), Al, K, Ti alumino-silicate glasses, rutile (T...

Sorghum is an important crop that can absorb and accumulate abundant Si ranging, improving tissue toleranceto the water salt stress reducing sodium absorption. T hus, objective was to verify induction of resistance ingermination seedling growth sorghum seeds during germination due treatment with silicon.Two experiments were carried out two cultivars (EA03 EA955) solution potassium silicatesolut...
