Abstract

This study was carried out to investigate characteristics of new garlic cultivar 'Alkae' and to identify the effect of scape removal on bulb characteristics and growth of garlic cultivar 'Alkae' and 'Namdo'. Bolting time and harvesting time were earlier about 20 days in 'Alkae' than those in 'Namdo'. 'Alkae' was inferior to 'Namdo' in top growth as plant height, number of leaves, leaf area, SPAD value, diameter of leaf sheath, and so on. but root developing was better in 'Alkae'. Bulb weight of' Alkae' was 17% more than that of 'Namdo', harvested on proper time. The ratio of bulb weight over 40 g was almost double in 'Namdo' as 48% with 'Alkae' as 25%. Occurrence of bulb cracking was more considerable in 'Alkae' and the number of clove per bulb was 1.9 more in 'Alkae' than 'Namdo', but the ratio of bulb rot during storage was higher in 'Namdo' than 'Alkae'. In treatments of scape removal, SPAD value did not show any difference between two cultivars. Leaf dryness was earlier and harder than control and leaf area showed the same tendency as leaf dryness, and there were no significant differences among the methods of scape removal. The bulb weight and the ratio of bulb weight over 40 g at 50 days after the harvest of 'Alkae', 'Namdo' were more 10%, 12% and 27%, 44% in scape removal treatment than control. and there were no significant differences among the methods of scape removal. So, scape removal was very effective to increase large bulb production in the two garlic cultivals and the effect was higher in 'Namdo' than 'Alkae'. The ratio of bulb cracking and the occurrence of bulb rot were almost same in with the scape removal and non removal groups And also there were no significant differences among the methods of scape removal.

마늘 신품종 '올캐'의 특성을 구명하고, 화경제거 유무 및 제거방법이 '올캐'마늘과 '남도'마늘의 생육 및 수량에 미치는 영향을 검토하였다. '올캐'마늘은 추대기 및 수확기가 '남도'마늘보다 20일 정도 빨랐다. 지상부 생장은 '남도'마늘보다 떨어졌으나 뿌리 발달은 좋았다. 각 품종의 수확적기에 수확할 경우 구 중량은 '남도'마늘이 '올캐'마늘 보다 20% 정도 많았다. 40g 이상의 대구 비율도 '남도'마늘이 48%로 '올캐'마늘 25%에 비해 두배 정도 많았다. 인편수는 '올캐'마늘이 '남도'마늘 보다 1.9개 정도 많았다. 열구 발생률은 '올캐'마늘이, 저장중 부패율은 '남도'마늘이 높았다. 화경을 제거할 경우 무처리에 비해 잎마름 속도가 빠르고 그 정도도 심했으나 화경제거 방법간에는 차이가 없었다. 엽면적은 잎마름률과 같은 경향이었다. 수확 50일 후의 구중은 화경 제거구가 무제거구에 비해 '올캐'마늘은 11%, '남도'마늘은 13%정도 많았다. 40g 이상의 대구 분포비율은 화경제거구가 무처리구에 비해 '올캐'마늘은 약 27%, '남도'마늘은 약 44% 정도 많았다. 따라서 두 품종 모두 화경을 제거해 주는 것이 대구 생산에 유리하며 특히 '남도'마늘은 화경제거 효과가 컷다. 화경제거 방법간에는 통계적인 유의차가 없었다. 열구 발생률과 저장중 부패율은 화경제거 유무 및 제거방법에 따른 차이가 없었다.
