ResumoAbstract Thioacetamide, thiourea, and 1-allyl-2-thiourea were effective in promoting germination of non-after-ripened seeds of “Lovell” peach. The activity of thioamides in promoting germination of dormant peach seeds appears to be dependent on tautomerism of the thioamide to form the thiol-imido configuration with both the thiol and imido groups being necessary for activity. A marked interaction between thiourea and α-naphthaleneacetic acid suggested that thioamides influence germination by their effect on auxin activity. Maleic hydrazide and kinetin had no effect on germination either alone or in the presence of thiourea. Gibberellic acid and thioamides appear to influence different mechanisms in promoting germination of dormant peach seeds.
