摘要

本試驗以荷蘭進口大花香石竹之穴盤苗為試驗材料，試驗品種包括‘凱迪那’、‘唐娜’及‘瑪拉嘉’等三品種，試驗地點為臺中區農業改良場溫室。試驗期間並記錄環境溫度。處理方式包括不摘心、一次摘心和二次摘心。結果顯示摘心處理延遲切花生產日數和增加植株分枝數。而以切花產量而言，一次摘心最多、不摘心次之、二次摘心為最少。三品種之切花鮮重、莖徑、花徑大小依序為不摘心＞一次摘心＞二次摘心。本試驗建議以一次摘心較為適宜，可降低大花香石竹生產成本和維持切花品質。

The materials of this experiment were use standard carnation plug-seedling imported from the Netherlands. Experimental cultivars include: ”Gaudina”, ”Dona” and ”Malaga”, and plant growth situation were in greenhouse of Taichung District Agricultural Research and Extension Station. The environmental temperatures was measured and recorded during experimental period. Treatments are non-pinching, single pinching and double pinching. Results showed the pinching treatments delayed production days and increased number of branches. The yield of flower stems indicated single pinching was more than non-pinching and double pinching. The orders of weights, stem diameters and flower diameters among these cultivars: non-pinching ＞ single pinching ＞ double pinching. For reducing the seedlng cost and maintaining the quality of cut-flower in standard carnation, this experiment suggests single pinching treatment could be a system for commercial produition.
