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.

The selenium content of soils varies greatly from 0.005 to 1200 μg/g, and most commonly between 0.1 and 10 μg/g. In selenium-deficient areas, the soil content may range from 0.005 to 2 μg/g.

The selenium content of plant foods, such as grains and seeds, depends on the selenium content of the soil in which they are grown. Selenium deficiency can lead to Keshan disease, affecting the heart muscle. Symptoms of selenium deficiency include muscular discomfort and weakness.

They belong to a number of different genera, including Aster, Atriplex, Castelleja, Grindelia, Gutierrezia, Machaeranthera, and Mentzelia. The primary indicator or selenium-accumulator species can accumulate from 100 to 10,000 mg Se kg -1 dry weight. This group includes species of Astragalus, Machaeranthera, Haplopappus, and Stanleya (14).

11-03-2020· Selenium exists in two forms: inorganic (selenate and selenite) and organic (selenomethionine and selenocysteine) [ 2 ]. Both forms can be good dietary sources of selenium [ 3 ].

Selenium is an essential nutrient in animals and humans but is not generally considered to be essential to plants. It has been found to be beneficial to some plants, however anything more than a trace amount can cause symptoms of toxicity. Selenium is also toxic to animals …

A soil test can confirm toxic levels of selenium in the soil and a tissue test can confirm toxic levels of selenium in plants.

The paper collected relevant literatures on selenium and explored the function to plant, selenium content, influential factors and selenium specification and transformation. We believed that there should be more deep research on function of selenium to plant. Approaches of molecular, genetic engineering and isotope could be employed to breed selenium rich crops and possibilities in practice.

Plants were grown hydroponically in nutrient solution characterized by excessive Mn content (19.2 mg dm ⁻³ ) and different contents of Se (control; 0.77, 1.05, 1.33 mg dm ⁻³ ).

A method of hydride generation atomic fluorescence spectrometry was applied to the determination of the selenium concentration of regular polished rice in China and selenium-enriched polished rice obtained by foliar application of selenium-enriched fertilizer in the forms of selenite and selenate. The average selenium content of regular rice was 0.025 ± 0.011 μg g-1. On the basis of a daily ...

23-07-2020· Selenium (Se) in soil mainly consists of selenite, selenate, and elemental Se. However, little is known about the mechanism involved in the uptake and biotransformation of elemental Se by plants. In this study, the uptake, translocation, subcellular distribution and biotransformation of selenium nanoparticles (SeNPs) in rice (Oryza sativa L.), and a comparison with selenite and selenate, were ...

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 with regard to Se uptake ...

The effects of nanoparticles (NPs) on plants are contrasting; these depend on the model plant, the synthesis of the nanoparticles (concentration, size, shape), and the forms of application (foliar, substrate, seeds). For this reason, the objective of this study was to report the impact of different concentrations of selenium (Se) and copper (Cu) NPs on yield, antioxidant capacity, and quality ...

Rapeseed plant: Ag, Cr, Hg, Pb, Zn: Phytoextraction. Se: Low rates of selenium volatilization from selenate-supplied Muskgrass (10-fold less than from selenite) may be due to a major rate limitation in the reduction of selenate to organic forms of selenium in Muskgrass. Chara canescens Desv. & …

Summary. In the present study the selenium and chromium content of different plant foods such as fruits, greens, flowers, vegetables, dried fruits, spices, condiments, cereals and pulses were analysed.

Selenium can increase the tolerance of plants to UV-induced oxidative stress, delay senescence, and promote the growth of ageing seedlings (Xue et al., 2001; Pennanen et al., 2002).

INTRODUCTION: SELENIUM IN SOILS, PLANTS AND ANIMALS. Selenium (Se) is an essential mineral element for both human and animal nutrition (White and Brown, 2010).In humans, Se deficiency is associated with hypothyroidism, cardiovascular disease, a weakened immune system, male infertility, cognitive decline and increased incidence of various cancers (Fairweather-Tait et al., 2011; Rayman, …

21-11-2019· The ubiquitous signaling molecule melatonin (N-acetyl-5-methoxytryptamine) (MT) plays vital roles in plant development and stress tolerance. Selenium (Se) may be phytotoxic at high concentrations. Interactions between MT and Se (IV) stress in higher plants are poorly understood. The aim of this study was to evaluate the defensive roles of exogenous MT (0 μM, 50 μM, and 100 μM) …

The selenium content and species of both plant and animal foodstuffs depend on environmental conditions, in particular, the quantity and species of selenium to which the animal/plant is exposed (6, 24).Selenomethionine is predominant in cereals, and selenium concentrations vary from 0.01 to 0.55 μg/g fresh weight (), whereas in other plant foods the content is generally lower, with the ...

Selenium is a mineral found in different concentrations in the soil and even appears in certain foods and a little amount in water. Selenium rich foods create a powerful combination of antioxidants when combined with vitamin E.Its great antioxidant properties provides you a healthier metabolism.
