Abstract: The effect of Fascination^TM和Pro-Gibb^? on the growth, inflorescence development and flowering of Ornithogalum 'Chesapeake Snowflake' was studied.The application of 200, 100, 50 and 10 ^μL 2% FascinationTM and 25, 50, 100 and 200 mg/L Pro -Gibb^? to the plants growing from bulbs, accelerated flowering of the inflorescence by 9 to 12 days and 6 to 12 days, respectively, as compared to controls.The application of 200, 100, 50 and 10 ^μL 2%Fascination^TM and 25, 50, 100 and 200 mg/L Pro -Gibb^? to the plants growing from bulblets, accelerated flowering of the inflorescence by 10 to 14 days and 8 to 14 days, respectively, as compared to controls.Scape length at flowering was not significantly affected by FascinationTM or Pro-Gibb^?.
