Abstract

Garlic (Allium sativum L.) is considered as one of the most important vegetables with various uses throughout the many countries. Also, it is one of the most economically important Allium species, and has been widely cultivated for more than 5,000 years. In Korea, garlic is planted in late summer and is grown from autumn and spring of the next year. Bulb starts to form when temperature rises under longer photoperiods. Garlic growth is affected by various factors such as storage conditions, humidity, duration of minimum temperature, and photoperiod. Also, the storage conditions for propagation seed are known to potentially affect future vegetative stages. In this study, we evaluated to effect of the inter-bud growth and growth of the southern-type cultivar 'Namdo' according to storage temperatures. The inter-bud growth, emergence & sprouting rate, and initial growth of stored garlic at low temperatures (5~15℃) exhibited robust growth, while garlic stored at high temperatures (30℃) was investigated to be sluggish compared to another treatments. However, the bulb diameter of stored garlic at 10 ℃ and 15℃ increased to 148.7% and 154.0 % compared to untreated garlic, respectively. Also, the bulb weight of stored garlic increased to 285.7% and 294.4% compared to control, respectively. In contrast, garlic stored at 5℃ showed a decrease of 70 .5% in bulb dimeter and 70 .6% in bulb weight compared to the control. As a results, it was confirmed that the storage temperature of garlic affects the inter-bud growth, emergence & sprouting rate, growth, bulb diameter, and bulb weight. These results will be to the possibility that is possible to estimate the growth cycle of garlic using the growth index for the improvement of crop modeling.

마늘(Allium sativum L.)은 다양한 용도로 사용되는 중요한 채소작물이며, 많은 국가에서 널리 재배되고 있다. 또한, 마늘은 파속 작물 중 경제적으로 중요한 작물로 약 5,000년 전부터 재배되었다. 일반적으로 한국에서 마늘은 늦은 여름부터 가을에 파종하여 겨울을 거쳐 기온 상승과 광주기가 길어지면 인경을 형성한다. 마늘의 성장은 저장조건, 습도, 최저온도, 광주기 등의 다양한 요인에 의해 영향을 받으며, 저장조건은 파종 후 마늘 생육 단계에 영향을 준다고 알려져 있다. 본 연구는 저장온도에 따른 난지형 마늘 '남도'의 내부엽 생장과 파종 후 생장에 미치는 영향을 평가했다. 저온에서 저장된 마늘(5~15℃)은 내부엽 생장, 출현 및 발아율과 초기생장은 매우 빠른 생육을 확인했으며, 고온에서 저장된 마늘(30℃)은 다른 조건에서 저장된 마늘에 비해 느린 것을 확인하였다. 그러나, 10~15℃ 저장 마늘 구경은 각각 무처리 마늘에 비해 148.7% 및 154.0% 증가하였으며, 구중은 무처리 대비 285.7% 및 294.4% 증가했다. 반면, 5℃ 저장 마늘의 구경은 무처리에 비해 70.5%, 구중은 70.6% 감소했다. 본 연구결과를 통해 마늘 저장온도는 내부엽 생장, 출현 및 발아율, 단계별 생육, 구경 및 구경 변화에 영향을 주는 것으로 확인했다. 이러한 결과는 작물 재배에 있어 마늘생육과 작물모델을 이해하는데 도움을 줄 수 있을 것으로 판단된다.
