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).

Selenium in plants and soil Got A Plant Problem?

Selenium Toxicity. Plants suffering from selenium toxicity may be stunted and may die earlier than usual. Leaves of affected plants may exhibit chlorosis or may dry and wither. 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.

Study on the Relationship between Soil Selenium and Plant

01-12-2005  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.

Managing the Selenium Content in Soils in Semiarid

The selenium level in most soils is generally less than 1 mg Se/kg soil; however, the selenium content in seleniferous soils can be as high as 4 to 100 mg Se/kg soil. The selenium content of plants in most soils is less than 1 mg/kg plant dry weight, whereas most plants grown in seleniferous soils show selenium levels in the range of 1 to 10 mg/kg plant dry weight.
