Abstract

Selenium is readily absorbed by all plants. However certain soils contain
selenium in amounts and forms that render some plants toxic to animals, plants
have been divided into two groups according to their ability to accumulate
selenium: (i) primary selenium-accumulators or indicator plants, which include
species of the Astragalus, Haplopappus and Stanleya genera. These plants
accumulate low molecular weight, water soluble organic compounds and selenate
(Anon., 1980) to give selenium levels of 50 to several thousand mg kg-1; and
(ii) non-accumulator plants which include grasses, shrubs, small grains, alfalfa
and some forbs. These plants usually accumulate less than 50mg kg-1 (generally
5-12mg kg-1) selenium as organic forms in plant proteins. Selenium poisoning
in livestock most frequently involves these non-accumulator plants.
