Journal ArticleDOI
Selenium biofortification of wheat grain via foliar application and its effect on plant metabolism
Túlio Silva Lara,Josimar Henrique de Lima Lessa,Kamila Rezende Dázio de Souza,Ana Paula Branco Corguinha,Fábio Aurélio Dias Martins,Guilherme Carpena Lopes,Luiz Roberto Guimarães Guilherme +6 more
TL;DR: In this paper, field trials were conducted to investigate the biofortification of selenium (Se) in wheat and also to assess the influence of foliar application of Se (as sodium selenate) on the metabolism of carbohydrates, nitrogen contents, and on the antioxidant system of the plants.
Journal ArticleDOI
Agronomic biofortification of rice ( Oryza sativa L.) with selenium and its effect on element distributions in biofortified grains
Josimar Henrique de Lima Lessa,Anderson Mendes Araujo,Liniker André Ferreira,Ediu Carlos da Silva Júnior,Cynthia de Oliveira,Ana Paula Branco Corguinha,Fábio Aurélio Dias Martins,Hudson Wallace Pereira de Carvalho,Luiz Roberto Guimarães Guilherme,Guilherme Carpena Lopes +9 more
TL;DR: The results suggest that soil application of 47 and 36 g ha−1 of Se (as sodium selenate) may guarantee the production of rice grains with adequate Se levels for human consumption in Brazil and worldwide, respectively.
Journal ArticleDOI
Strategies for applying selenium for biofortification of rice in tropical soils and their effect on element accumulation and distribution in grains
Josimar Henrique de Lima Lessa,Jéssica Francisco Raymundo,Ana Paula Branco Corguinha,Fábio Aurélio Dias Martins,Anderson Mendes Araujo,Franklin Eduardo Melo Santiago,Hudson Wallace Pereira de Carvalho,Luiz Roberto Guimarães Guilherme,Guilherme Carpena Lopes +8 more
TL;DR: Although Se application did not change the rice yield, it affected some enzyme activities, improving the antioxidant system of the plant and showed that the strategies and rates of Se applied to the plants were effective for producing Se-rich rice grains.
Journal ArticleDOI
Soil management and ionic strength on selenite retention in oxidic soils
Anderson Mendes Araujo,Josimar Henrique de Lima Lessa,Liniker André Ferreira,Luiz Roberto Guimarães Guilherme,Guilherme Lopes +4 more
TL;DR: In this paper, the influence of soil management and ionic strength on selenium retention in Brazilian soils was evaluated in 16 soil samples (eight from cultivated soils and eight from native soils), using solutions containing 100 and 500 µg L-1 Se in the form of sodium selenate and in two IS, 15 and 150 mM.
Journal ArticleDOI
Selenium desorption in tropical soils by sulfate and phosphate, and selenium biofortification of Mombaça grass under increasing rates of phosphate fertilisation
Maria Jéssica Vieira dos Santos,Josimar Henrique de Lima Lessa,Mateus Belisário de Assis,Jéssica Francisco Raymundo,Bruno Teixeira Ribeiro,Luiz Roberto Guimarães Guilherme,Guilherme Carpena Lopes +6 more
TL;DR: In this article, the authors evaluated the adsorption of selenate (SeVI) and selenite (SeIV) in two oxidic soils with contrasting soil texture and assessed effects of phosphate and sulfate as competitive anions on Se desorption.
