Abstract
The promotion of flowering in small Dutch iris (Iris X hollandica Hoog ., cv. 'Ideal') bulbs by treatment for 24 h with 10 mu l 1(-1) ethylen e was associated with enhanced respiration, which continued long after the end of ethylene treatment. Shorter ethylene treatments, which wer e partially effective in inducing flowering, resulted in lower and sho rter bursts of respiration. Changes in the soluble carbohydrate conten ts of the ethylene-treated bulbs were not detected until following the cold treatment. The possible mechanisms by which ethylene stimulates flowering are discussed.
