摘要：

In the experiment with white clover sodium selenite was applied (I) over the foliage mixed with superphosphate. (2) over the foliage in solution, (3) to {he soil in solution without touching the herbage. Selenium was taken in readily through the leaves, particularly from the solution, and distributed to stolons and roots. Uptake through the roots was much slower. In (3) the concentration of selenium was in the order: roots> stolons> nodules> leaves and petioles.Browntop was treated with sodium selenite in solution as in (2) and (3) for white clover, together with a control treatment. It showed little eviden~e of ability to absorb selenium through the leaves, but a very much Greater ability than white clover to absorb it through the roots.
