Abstract
本研究旨在建立長壽花 (Kalanchoe blossfeldiana Poelln.) 小品盆花冬季促進開花技術、夏季育苗技術及觀賞品質提升技術。以 ‘齊兒’ 15/10℃之不加溫處理模擬冬季低溫環境，18、23 及28℃根溫處理可增加開花數，而28℃根溫處理可有效提早開花10.3 日。不耐熱品種 ‘巴黎’ 於冷房控制氣溫25/20℃處理，較夏季以雙層遮陰網處理，其株高、展幅及側芽均顯著較佳，且缺株率也能由33.3%降至5.6%，可提升採穗率。7 個長壽花品種於不同光度環境或澆水頻度對觀賞壽命之影響因品種而異，高光度環境下依品種不同可較低光度環境延長觀賞15.0-30.4 日，‘嬌滴滴’ 及 ‘柏金’ 對低光度環境之耐受性較佳，‘黃襯衫’ 及 ‘泰珍妮’ 則較差；所有品種在不澆水處理下均顯著發生葉片下垂情形，以‘柏金’ 品種對低澆水頻度之耐受性最佳，而 ‘泰珍妮’品種在低澆水頻度落葉及花莖下垂嚴重，觀賞期最短。
This study was conducted to establish these techniques of flowering promotion in winter, seeding in summer and quality enhancement in interior condition of mini-potted kalanchoe. Flower numbers of mini-potted kalnchoe ‘Calandiva Cher’ controlled approximately 18, 23 and 28℃ of root temperature more than which placed in 15/10℃ simulated the low temperature condition in winter. And root
temperature enhanced to 28℃ could earlier flowering 10.3 days effectively. Low heat tolerance variety ‘Paris’ in 25/20℃ cool treatment with better height, width and shoot numbers than double shading nets in summer, and death rate declined from 33.3% to 5.6% and the cutting-rate increased. The potted qualities of seven varieties placed three positions or cared by three watering frequencies
affected by varieties. The longevity of potted kalanchoe under higher light condition varied with varieties, range from 15.0 to 30.4 days. ‘Jodie’ and ‘Berkin’ are more tolerant to low light; ‘Karen’ and ‘Tageina’ are rather poor not. All varieties with no watering treatment, showed leaves wilting. ‘Berkin’ is tolerant to no watering; ‘Tangina’ with few watering and no watering cause leaf dropout, flower stem drooping and shortest longevity.
