Generation of selenium-enriched rice with enhanced grain yield, selenium content and bioavailability through fertilisation with selenite

Supplemental selenium improves wheat grain yield and quality through alterations in biochemical processes under normal and water deficit conditions

“…Contradictory results showed that soil and foliar application of Se did not significantly increase P and K concentration in maize grains (Wang et al 2013).The grain Zn concentration decreased by 42% under water deficit conditions with respect to normal plants. It was observed that grain Zn concentration increased by exogenous Se supply (Fig.…”

“…seed dressing is also suggested in the literature (Wang et al 2013). In the present study, a significant increase in almost all yield and yield components of wheat was noted by Se application.…”

Effect of Selenite and Selenate Application on Mineral Composition of Lettuce Plants Cultivated Under Hydroponic Conditions: Nutritional Balance Overview Using a Multifaceted Study

“…On the other hand, considering alfalfa, chicory and cucumber, the Se concentration levels were comparable. 13,16,20,21,50 However, the larger the Se uptake the greater may be its influence in other nutrient absorption and it may upset the nutritional balance of the plant. Thus, for a better understanding of this influence, the results obtained for the nutrient concentrations were also evaluated by principal components analysis.…”

Selenium Biofortification in Rice - A pragmatic perspective

“…Selenium is mainly absorbed in the duodenum by enterocytes (through aminoacid transport systems) and catabolized into elemental selenium that therefore gets incorporated into glutathioneperoxidase (Rayman, 2008;FairweatherTait et al, 2011 (Fairweather-Tait et al, 2011), namely brain, kidney, heart, spleen, muscles and gonads (Kumar and Priyadarsini, 2014). In this context, Wang et al (2013) found that selenium bioavailability in biofortified rice about 80% of this nutrient remained in the organic form, and that the main species of seleno-bound protein were Se-methionine and Secysteine. Additionally, the concentration of the water soluble Se-cysteine was below the detection limit (4.6 g / L).…”

“…Hawrylak and Szymanska, 2004). In a study conducted by Wang et al (2013), rice sprayed with 10.5g and 21 g of selenite/hectare produced more tillers per plant, more grains per panicle, bigger grains and higher yields. Additionally, this treatment also shortened the number of days to heading, leading to an earlier maturity of rice.…”
