Soluble silicon

A fluorescent probe based on silicon quantum dots (SiQDs) was developed for the selective and sensitive detection of oxytetracycline (OTC) via the inner filter effect (IFE). The water-soluble fluorescent SiQD was synthesized based on the reaction of 3-Aminopropyltriethoxysilane (APTES) and sodium citrate as precursors by the one-pot hydrothermal process. The strong fluorescence emission of quantum dots (QDs) was obtained at 440 nm when excited at 350 nm and OTC had a broad absorption band between 200 and 400 nm.

A field experiment was conducted in kharif season of 2015 to investigate the influence of silicon solublizer on different rice genotypes namely PA-6129, PA-6201, PA-6444, PHB71, US-312, and BPT-5204. Soil application of silicon solubilizers was given at the time of maximum tillering, panicle initiation and 50% flowering stage. The experiment was arranged as split plot design with three treatments and three replications.

Finger millet or ragi is the primary food source for millions of people in tropical dry land regions of Africa and Asia. Two field experiments were conducted to study the genotypic variation for silicon accumulation and the effect of foliar applied silicic acid on growth, nutrient uptake and blast disease resistance of ragi. Study showed a significant varietal variation for Si accumulation with an average Si content of 1.67 % in the above ground part.
