in order to study the effects of foliar application of zn and k on yield and some physiological traits of spring safflower (carthamus tinctorius l.), cv. esfahan 14, under drought stress, a pot experiment was conducted in research greenhouse of yasouj university. experiment was a factorial based on completely randomized design with three replications. factors consisted of drought stress (s1- wi...

Together with longer production periods, the commercial transition to day-neutral strawberry (Fragaria × ananassa) varieties has favored the development of diseases such as powdery mildew (Podosphaera aphanis) that thrives in late summer-early fall. In an attempt to find alternative solutions to fungicides currently employed to curb the disease, we wanted to investigate the potential of silicon...

Electrodeposition of silicon in molten CaCl2 has been drawing increasing attention. Soluble silicate anions the melt can be reduced and tailored into functional materials. To ensure a precise control electrochemical processes, comprehensive knowledge on soluble is indispensable. Here, we clarify formation behavior by dissolving solid CaSiO3 Ca2SiO4 at temperatures from 1047 K to 1233 (774 °C 96...

Hydrothermally grown crystals of beta-K3NdSi6O15, potassium neodymium silicate, have been studied by single-crystal X-ray methods. Under appropriate conditions, the compound crystallizes in space group Bb2(1)m and has lattice constants a = 14.370 (2), b = 15.518 (2) and c = 14.265 (2) A. There are 30 atom sites in the asymmetric unit of the basic structure. With eight formula units per unit cel...

in order to investigate the effect of silicon application on some physiological characteristics and growth of wheat (triticum aestivum l.) under late drought stress condition, an experiment was conducted at the agriculture and natural resources university of ramin, khuzestan during year 2012. the experiment was conducted in the open environment as factorial randomized complete block design with...

For many years silicon (Si) deficiency in crops was relatively unknown and this element was widely regarded as non-essential for plant growth. Ever since the discovery by D’Hotman De Villiers, in 1937, that sugarcane growing on highly weathered soils in Mauritius could be rejuvenated, by applying finely crushed siliceous basalt, silicon has emerged as an important nutrient for sugarcane. With t...

In this work, we report high biological performance of silicon substituted nano hydroxyapatite (nHA) prepared by immersion of calcium phosphate and sodium silicate as precursors in Simulated Body Fluid (SBF) solution for 24, 36, 48 and 72 hrs at 37°C. Characterization and chemical analysis of the synthesized powders were performed by Fourier transform, infrared spectroscopy (FT-IR), X-ray powde...
