초록
본 실험은 해발 800 m의 대관령에서 가을감자 기본종 생산을 위한 분무경 재배시 적품종을 선발하기 위해 수행하였다. 분무경 재배방법은 3분에 20초씩 양액을 분사하였고, 두께 30 mm스티로폼 위에 직경 20 mm구멍을 뚫고9월5일 정식하여, 11월 12일에 수확하였다. 시험품종은‘대서’, ‘대지’, ‘하령’, ‘홍영’, ‘자영’, ‘조풍’, ‘조원’, ‘남서’, ‘서홍’, ‘수미’ 등 10품종을 공시하여 생육 및 수량을비교하였다. 생육초기의 경장은 ‘하령’, ‘자영’, ‘서홍’ 등3품종이 대조구인 수미보다 좋았으나, 생육후기에는 큰차이를 보이지 않았다. 또한 생육초기의 뿌리 생육은 ‘수미’가 좋았으나, 생육 후기로 갈수록 ‘자영’, ‘서홍’, ‘자영’ 등 3품종이 크게 증가하였다. 복지생체중은 36 ~ 48.6 g 범위였으며, ‘서홍’>’수미’>’자영’>’홍영’ 순으로 무거웠다. 특히, 괴경수는 ‘조원’품종이 22.4개/주로 ‘수미’ 품종의 11.3개에 비해 2배 이상 많았다. 따라서 가을감자 기본종 생산을 위한 분무경 재배시 적품종은 ‘서홍’, ‘자영’,‘홍영’, ‘조원’ 등 4품종이었다.
Abstract
The present study was performed to select suitable potato (Solanum tuberosum L.) varieties for double cropping in seed production using aeroponic system, the nutrient solution was sprayed for 20 seconds in every 3minutes, and potatoes were planted into styrofoam at a distance of 25 cm between plants. Transplantation was completed in September 9 and potatoes were harvested in November 12. The 10 trial cultivars, ‘Atlantic’, ‘Dejima’,‘Haryong’, ‘Hongyoung’, ‘Jayoung’, ‘Jopung’, ‘Jowon’,‘Namsuh’, ‘Seohong’, ‘Superior’ were examined for growth and yield. The shoot growth of all cultivars at the early stage was better than ‘Superior’, however, no difference was observed at the late stage of plant growth. In addition,‘Superior’ showed a excellent root growth during the early plant growth stage, however, increased root growth was only found in ‘Jayoung’, ‘Seohong’, during the late plant growth stage. The stolon weight was greater in the order of ‘Seohong’>‘Superior’>‘Jayoung’>‘Hongyoung’. Particularly, the number of tuber in ‘Jowon’ was 22.4/plant that was over twice than ‘Superior’(11.3/plant). As results of the current study, therefore,we concluded that four cultivars ‘Seohong’, ‘Jayoung’,‘Hongyoung’, ‘Jowon’were the most suitable cultivars for basic seed production using aeroponic system in Autumn potato.
