Estudio de la bioaccesibilidad in vitro de zinc en arroz (oryza sativa) y su relación con el contenido de ácido fitico

Rev. chil. nutr; 47 (2), 2020
La bioaccesibilidad de un nutriente en un alimento sirve para determinar la calidad nutricional de éste para el consumo humano. El arroz es uno de los alimentos más importantes en la dieta por su gran aporte calórico y nutricional. El objetivo de este estudio fue analizar la bioaccesibilidad in vitro ...

Chemical characterization of the antioxidant, antihyperglycemic and antihypertensive capacities of red rice (Oryza sativa L. ) whole flour

Rev. chil. nutr; 47 (2), 2020
Oryza sativa L. rice has large amounts of proteins and minerals, besides presenting several pigmented varieties. Red rice is distinguishable due to its great nutritional value compared to the regular white variety. Its red pericarp pigmentation is due to the bioactive compounds that are responsible for i...

Single cell oil production by a novel yeast Trichosporon mycotoxinivorans for complete and ecofriendly valorization of paddy straw

Background: Oleaginous yeasts can be grown on different carbon sources, including lignocellulosic hydrolysate containing a mixture of glucose and xylose. However, not all yeast strains can utilize both the sugars for lipogenesis. Therefore, in this study, efforts were made to isolate dual sugar-utilizing...

Riparian forest fragments in rice fields under different management: differences on hymenopteran parasitoids diversity

Braz. j. biol; 80 (1), 2020
Abstract Hymenopteran parasitoids are important biological control agents in agroecosystems, and their diversity can be increased with habitat heterogeneity. Thus, the purpose of the study is to evaluate the influence of distance of rice-growing areas from natural fragment, type of crop management (organ...

Spatialization of Tibraca limbativentris Stål in irrigated rice: a geostatistical approach

Arq. Inst. Biol; 87 (), 2020
The objective was to identify the dispersion of Tibraca limbativentris (Hemiptera: Pentatomidae) in different phenological phases of irrigated rice. The research was carried out in an area of 20.12 ha, subdivided in four fields of 0.25 to 14.1 ha with the irrigated rice culture, grown under the technical...

The influence of ultra-high diluted compounds on the growth and the metabolites of Oryza sativa L

Int. j. high dilution res; 19 (1/2), 2020
The ultra-high dilutions (UHDs) have been widely used in the field of human, animal and plant treatment. In the present research, the effects of the potentized ultra-high dilutions (UHDs) on physiological and biochemical variations in Oryza sativaL. (rice) were investigated. Methods: To study the effect ...

Possible Metsulfuron Herbicide Detoxification by a Oryza sativa L. Glutathione S-transferase Enzyme

Abstract Rice (Oryza sativa L.) is one of the most important crops in the world, and it is considered the primary source of nutritional layout in developing countries in Asia. The glutathione S-transferases (GSTs) superfamily confers to rice protection against biotic and abiotic stress, and herbicide res...

Silicon Mediated Alleviation of Salinity Stress Regulated by Silicon Transporter Genes (Lsi1 and Lsi2) in Indica Rice

Abstract Silicon accumulation is known to improve tolerance of plants under both biotic and abiotic stress. Salinity stress is an inevitable crisis causing wide spread damage to rice leading to food insecurity. The influence of Si (1mM) on two rice cultivars cv. Ghanteswari (high accumulator) and cv.Bada...

Studies on the cold tolerance of ratoon 'Chaling' common wild rice

Biol. Res; 53 (), 2020
BACKGROUND: Rice is the staple food of many people around the world. However, most rice varieties, especially widely grown indica varieties and hybrids, are sensitive to cold stress. In order to provide a basis for the utilization of a common wild rice (CWR, Oryza rufipogon Griff.) named 'Chaling' CWR in...

Silicon sources for studies of rice plants in nutrient solutions

Biosci. j. (Online); 35 (6), 2019
The objective of this work was to evaluate the effects of various Si sources currently used in studies of Si doses in nutrient solutions on dry matter yield and the accumulation of nutrients and Si in rice plants. Treatments of rice plants with three sources of Si (monossilicic acid, sodium ...
