눈 조직의 저온열방출방법을 통한 포도 품종의 내한성 분석

Cold Hardiness Evaluation of Grapevine Buds by Low Temperature Exotherms among Several Grape Cultivars

최근 국내 재배가 많거나 국내 도입이 되고 있는 13개 포도품종의 눈을 대상으로 LTE를 측정한 결과 ‘Shooting Star’, ‘Muscat Bailey A’, ‘IFG-6’, ‘Vanessa Seedless’, ‘Summer Crispu’, ‘Shine Muscat’, ‘Jelly Pop’, ‘Campbell Early’, ‘Ruby Seedless’, ‘My Heart’, ‘Kyoho’, ‘Thompson Seedless’, ‘Violet King’ 순으로 저온에 강한 것으로 나타났다. LTE 값은 ‘Shooting Star’에서 -18.9℃로 가장 낮게 나타났으며, ‘Violet King’ 에서 -12.5℃로 가장 높게 나타났다. 이러한 결과를 통해 국내재배 시 기준 품종으로 제시되고 있는 ‘Campbell Early’와‘Kyoho’를 기준으로 데이터를 상대 비교함으로써 효율적으로지역별 재배 가능 여부를 판단할 수 있는 기초 자료로 활용할 수있다.

As a result of low temperature exotherm (LTE) measurement targeting the buds of 13 grape cultivars that are recently cultivated or introduced in Korea, ‘Shooting Star’, ‘Muscat Bailey A’, ‘IFG-6’, ‘Vanessa Seedless’, ‘Summer Crispy’, ‘Shine Muscat’, ‘Jelly Pop’, ‘Campbell Early’, ‘Ruby Seedless’, ‘My Heart’, ‘Kyoho’, ‘Thompson Seedless’, and ‘Violet King’ in order of being resistant to low temperatures. The LTE value was the lowest at -18.9℃ in ‘Shooting Star’ and the highest at -12.5℃ in ‘Violet King’. Through these results, it can be used as basic data to determine whether or not cultivation by region is possible efficiently by comparing data based on ‘Campbell Early’ and ‘Kyoho’, which are presented as standard varieties for domestic cultivation
