SUMMARY The germination rate of turions produced in a medium without gibberellic acid depends on the time the turions spend in this medium. Gibberellic acid in light enhances the germination rate of turions harvested when turion production has just started. Kinetin enhances the germination of such turions in light and in darkness. The highest germination rate in light is obtained when both kinetin and gibberellic acid are added to the medium. Turions produced in a medium with gibberellic acid do not require a cold treatment for rapid germination in light and darkness.
