Zusammenfassung:	Ethephon was sprayed on Euphorbia pulcherrima Willd. ex Klotzsch (poinsettia) 'Sonora Jingle' and 'Sonora White' to control their height and produce more compact potted plants. The results showed that Ethephon could effectively control the growth of 'Sonora Jingle' and 'Sonora White' poinsettia. Height was reduced by was 33.4±0.8% for 'Sonora Jingle' and 30.8±1.3% for 'Sonora White' poinsettia, when 700 mgㆍm-¹ Ethephon was sprayed three times on 29 August, 20 September, and 13 October 2005, respectively. Similar to other plant growth retardants, side effects including phytotoxicity and delays to first bract color were also observed on Ethephon treated poinsettia. However, all plants produced were still of a marketable quality.
