Selenium-Accumulating Plants : USDA ARS

The secondary selenium accumulators include some native range plants, and crop plants such as western wheatgrass, barley, wheat, and alfalfa. Plants containing more than 5 ppm selenium are potentially toxic in cattle. Where Selenium-Accumulating Plants

Selenium in plants and soil

Some plants can safely accumulate very large amounts of selenium while others cannot so do not be surprised if adjacent plants are affected in different ways. A soil test can confirm toxic levels of selenium in the soil and a tissue test can confirm toxic levels of selenium in plants. Guidelines may differ in your area but generally, if the

Selenium Health Professional Fact Sheet

Mar 11, 2020· The selenium content of soil affects the amounts of selenium in the plants that animals eat, so the quantities of selenium in animal products also vary [2,5]. However, selenium concentration in soil has a smaller effect on selenium levels in animal products than in plant-based foods because animals maintain predictable tissue concentrations of

Selenium forms and methods of application differentially

Selenium (Se) is an essential microelement for humans and a beneficial element for plants. Recently, biofortification with Se has emerged as a key strategy to increase crop Se content. Nonetheless, Se species matters a lot as inorganic Se species is mostly toxic to human health. In this study, we in

Study on the Relationship between Soil Selenium and Plant

Various extraction methods have been used to determine selenium (Se) concentrations in soils and plants in the second seleniferous regions of China. Our results show tea Se contents in the study area range from 1.009 to 2.6 mg/kg, which reveal that the tea areas in Ziyang County are in seleniferous regions. The four extraction methods evaluated in this study provide different information

Selenium in higher plants: understanding mechanisms for

Aug 01, 2009· Selenium (Se) is an essential micronutrient for many organisms, including plants, animals and humans. As plants are the main source of dietary Se, plant Se metabolism is therefore important for Se nutrition of humans and other animals. However, the concentration of Se in plant foods varies between areas, and too much Se can lead to toxicity.

SELENIUM IN HIGHER PLANTS Annual Review of Plant Biology

Abstract Plants vary considerably in their physiological response to selenium (Se). Some plant species growing on seleniferous soils are Se tolerant and accumulate very high concentrations of Se (Se accumulators), but most plants are Se nonaccumulators and are Se-sensitive. This review summarizes knowledge of the physiology and biochemistry of both types of plants, particularly

Selenium in plants: Boon or bane? ScienceDirect

Oct 01, 2020· Selenium resembles sulfur (S) chemically and shares a similar pathway for uptake and translocation in plants. For example, SeO 3 2− and SeO 4 2− are analogs of SO 3 2− and SO 4 2−, respectively.Therefore, they can compete with each other in acidic conditions (Golob et al., 2016; González-Morales et al., 2017).Among the Se species, SeO 4 2− uses SO 4 2−

Selenium Fact Sheet for Consumers

Dec 10, 2019· Selenium is found naturally in many foods. The amount of selenium in plant foods depends on the amount of selenium in the soil where they were grown. The amount of selenium in animal products depends on the selenium content of the foods that the animals ate. You can get recommended amounts of selenium by eating a variety
