Stimulation of germination of dormant seeds of Townsville style by selenomethionine

Dormancy of scarified seeds of Stylosanthes humilis was broken by seleno-1- methionine (SeM), a phenomenon inhibited by aminoethoxyvinylglycine and res tored by 1-aminocyclopropane-1-carboxylic acid. Additive effects of SeM wit h other promoting factors were not observed unless the latter also stimulat ed germination to a relatively great extent. This germination enhancement o ccurred regardless of any ethylene-like effect displayed by SeM.
