Abstract

The objective of this study was to find out the most optimal bulbil size and planting densities of garlic bulbils to germination for production of leaf garlic. In the first this experiment, the bulbils classified by the size of bulbil to Big (>0.2) and Small (≤0.2), were planted at 13,680 bulbils/m2 and 18,240 bulbils/m2 (Big), 18,240 bulbils/m2 and 22,800 bulbils/m2 (Small), respectively. The germination rate, plant height and total yield were measured. In the second experiment, length, width, fresh weight and dry weight of 200 garlic bulbils were measured to analyze the correlation of days to first germination, T50 and germination rate. In the first experiment, the germination rate showed the highest at Big bulbils. The density of 18,240 bulbils/m2 was the most suitable for cultivation because of the highest germination rate. In the case of yield, it was found that both of the fresh weight and the dry weight of Big bulbil was 2.8 times heavier than Small bulbil. Therefore, Big bulbil with the density of 18,240 bulbils/m2 was the most suitable for cultivation because of the highest yield. The correlation between each factor of morphological characteristics had a positive correlation between fresh weight, dry weight and width. Also, the germination rate had a positive correlation with fresh weight and width. And, days to first germination and T50 had a negative correlation with fresh weight and width. In conclusion, the optimal planting density is 18,240 bulbils/m2 and the optimal size of bulbil was 0.2g or more. However, thicker and heavier bulbils could lead to higher and faster germination.

본 연구는 잎마늘 생산을 위한 마늘 주아의 최적 주아 크기와 재식밀도를 알아보기 위함이다. 첫번째 실험에서 0.2g 이상의 주아를 대주아로, 이하를 소주아로 나눈 후 대주아는 13,680bulbils/m2와 18,240bulbils/m2, 소주아는 18,240bulbils/m2와 22,800bulbils/m2의 재식밀도로 치상 하였다. 발아율, 초장과 총 수확량을 측정하였다. 두번채 실험에서, 200립의 박피된 주아의 길이, 폭, 생체중과 건 물중는 발아시, 발아기와 발아율의 상관를 분석하기 위 해 측정되었다. 첫번째 실험에서, 발아율은 대주아에서 가장 높았다. 잎마늘 재배를 위해 재식밀도18,240bulbils/m2가 가장 높은 발아율 때문에 가장 적당한 재식밀도였 다. 수확량의 경우 생체중과 건물중 모두 대주아가 소주 아에 비해 2.8배 가량 높은 것을 알 수 있었다. 주아의 형태적 특성과 생체중과 건물중 및 폭 간은 정의 상관 을 보였다. 또한 발아율은 생체중과 폭간의 정의 상관을 보였다. 그리고 발아시와 발아기는 생체중과 폭 간의 부 의 상관을 보였다. 그럼으로, 결론적으로, 적정 재식밀도 는 18,240bulbils/m2의 재식 밀도와 0.2g 이상의 주아 크 기였다. 그러나, 더 두껍고 두 무거운 주아가 더 높은 더 빠른 발아율을 이끌 수 있다.
