摘要

紫羅蘭依販賣市場不同而在切花採收時選擇不同的小花開放程度，試驗結果顯示以國內市場為目的時，應在花穗小花開放達1/2時採收，而以外銷日本市場為目的時，由於必須經過一段貯藏期，以花穗小花開放達1/3時採收，如此才能有最好的瓶插壽命。在品種的表現方面，本試驗採用的品種以「黃波」表現最優良。而保鮮劑處理以市售的乙烯抑制劑可利鮮AVB預措4小時瓶插壽命最長，同樣為乙烯抑制劑的MCP，抑菌劑8HQS以及其加入2%蔗糖的預措處理組效果次之，以沒有預措的對照組瓶插壽命最短。

This study is to prolong the vase life of stock by different developmental stages of racemes and preservative treatment. The developmental stages of racemes may be different due to the market demand. For the domestic market the developmental stages of racemes should be harvested when 50% florets blooming. The developmental stages of racemes should be earlier because the handling and shipping will take a week for the Japan market, therefore, 33% florets blooming is the optimum stage. The vase life of the cultivars have different result, and the 'yellow wave' is excellent in the test cultivars. The vase life was improved by all preservative treatment. The Chrysal AVB pre-treat 4 hours had 90% of floret blooming. It was better than 8-HQS, 8-HQS with 2% sugar, and 1-MCP 4 hours pre-treat.
