Abstract

This experiment was conducted to select optimal cultivars of long leaf vase life for flower arrangements among 21 Hosta cultivars that were selected based on their ornamental value. As a result of the investigation, the cultivar with the longest leaf vase life was 'June' with 29 days record. The cultivars with a more than 10 days record were 'Remember Me', H. lancifolia var. grandiflora, 'Grand Marquee', 'Dress Blue', 'Blue Dimples', 'Frosted Dimples', 'Birchwood Park's Gold', 'Krossa Regal', and 'Paradise Power'. These 10 cultivars had a high chlorophyll content, and had low chlorophyll content changes over time and were high in water absorption. The 10 selected cultivars had equal characteristics of increase in chlorophyll content within a certain period of time. These cultivars have a longer vase life when compared to others. This indicates the potential to develop better materials be use with flower arrangements.

Hosta 품종 중에서 관상가치가 있는 21종을 선정하여 절엽 소재로 개발하고자 2009년 7월 1일부터 8월 15일까지 광도 750Lux, 온도 $28{\pm}2^{\circ}C$, 습도 52% 의 실내 환경 조건에서 수명을 조사하였다. H. 'June'의 절엽 수명이 29일로 가장 길었으며 10일 이상 수명을 유지한 품종은 'Remember Me', H. lancifolia var. grandiflora, 'Grand Marquee', 'Dress Blue', 'Blue Dimples', 'Frosted Dimples' 'Birchwood Park's Gold', 'Krossa Regal', 'Paradise Power'였다. 이 10가지 품종의 특정은 엽록소 함량이 높고, 경과시간에 따른 엽록소 함량의 변화가 적었으며, 물 흡수력이 높았다. 또한 처리 후 일정기간 엽록소 함량이 증가하였으며, 다른 Hosta, 속 품종에 비해 수명이 길어 화훼장 식용 절엽으로 개발이 가능한 품종으로 선발되었다.
