    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 GrowSelenium 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.

  • Rate-Limiting Steps in Selenium Plant Physiology

    The Se distribution in roots and shoots was different when plants were supplied with different concentrations of selenate: At 0 to 20 μ m external selenate, most of the Se was translocated to the shoot, but at 50 to 200 μ m, most of the Se remained in the root. In selenite-supplied plants only approximately 10% of the Se was translocated toSelenium, Vitamin D, Glutathione and COVID-19 Dr,Sep 28, 2020· We actually tried to start a project, or had an idea for a project, to look at tree rings and look at the concentration of selenium in tree rings so you could go back 100 years or something and just see what’s happening in different parts of the country and is there a decrease in selenium content towards, you know, more recent times.
