Scale wounding significantly accelerated flowering of Tulipa gesneriana L. bulbs that had been stored for 3,6 and 9 weeks at 2°C for ‘Apeldoorn’ and for 3 and 6 weeks for ‘Oxford’. In addition, final scape length was significantly longer in plants produced from wounded bulbs after 3 and 9 weeks of precooling for ‘Apeldoorn’ and after 3 weeks for ‘Oxford’. Wounding increased ethylene production in all treatments of both cultivars. ‘Oxford’ produced significantly more ethylene than ‘Apeldoorn’, however, the increased ethylene production did not produce floral abortions.
