Abstract

This experiment was carried out to select the desirable welsh onion (Allium fistulosum L.) varieties for the year-round cultivation in water culture. Ten varieties were tested, of which five were Korean's and the other five were Japanese's. The germination percentage and germinative energy of most varieties we.e more than 90 percent. The fastest germination speed were 'Geumjanguedaepa', 'Gujopa' and 'Fuyune'. The best growth of the varieties were 'Geumjanguedaepa' and 'Tokyokuro' in spring, 'Geumjanguedaepa', 'Gujopa', 'Saesaeksisilpa' and 'Tokyokuro' in summer, 'Geumjanguedaepa', 'Gujopa' and 'Tokyokuro' in fall, and 'Geumjanguedaepa', 'Midorigawa' and 'Tokyokuro' in winter cultivation. Suitable varieties of growth fur all seasons were 'Geurnjanguedaepa' and 'Tokyokuro', though 'Gujopa' was good in summer and fall. In the view of nutritional content, nitrate content was significantly lower in 'Geumjanguedaepa', 'Tokyokuro' and 'Fuyune' than that in'Saesaeksisilpa' and 'Starziam'. Vitamin C content was higher in 'Aqua Green', 'Midorigawa' and 'Seoulbaekpa' than that of the others. Pyruvic acid content was the highest in 'Geumjanguedaepa' and 'Suckchanguedaepa'. Based on the above results, 'Geumjanguedaepa', 'Gujopa' and 'Tokyokuro' were selected as the most desirable young welsh onion varieties for the year-round water culture.

실파는 생육기간이 짧고 온도 적응성이 높아 주년생산이 가능한 작목으로, 국내에서는 양념채소 및 다양한 쌈 채소류의 일부로 최근부터 수경 재배되고 있으나 실파의 수경재배에 필요한 재배기술이 확립되어 있지 않았다. 따라서 고품질 실파의 안정적인 주년생산을 위한 수경재배에 적합한 실파 품종을 선발하고자 본 시험을 수행하였다. 국내 5품종과 일본 5품종 등 총 10품종을 공시하여 봄부터 겨울까지 작형별로 담액순환방식으로 재배하였다. 발아율과 발아세는 대부분의 품종이 $90\%$이상이었으며 발아속도는 '금장외대파', '구조파' 및 '후유네'가 가장 높았다. 봄 작형에서 외형적 생육은 '토쿄구로'와 '금장외대파'가 가장 우수하였다 여름 작형에서는 '금장외대파', '구조파', '새색시실파' 및 '토쿄구로', 가을 작형에서는 '금장외대파', '구조파' 및 '토쿄구로', 겨울 작형에서는 '금장외대파', '미도리가와', '토쿄구로'가 우수하였다. 종합하면, 연중 작형에 '금장외대파'와 '토쿄구로'가 적합하였고 또한 여름과 가을작형에는 '구조파'도 적합하였다. 내적 품질 측면에서 측정한 봄 작형의 vitamin C 함량은 '아쿠아그린', '미도리가와', '서울백파'가 높았으며, nitrate 함량은 '금장외대파', '후유네' 및 '토쿄구로'가 낮았고, pyruvic acid 함량은 '석창외대파', '금장외대파' 및 '구조파'가 높았다. 이상의 결과를 토대로 '금장외대파'와 '토쿄구로' 및 '구조파' 3품종을 담액순환식 수경재배용 실파 품종으로 선발하였다.
