Abstract

In Ulrung floral community the growing environments and nutritive values of wild garlic was investigated. The wild garlic, grown for $3{\sim}4\;years$ in community area, were able to develope bulbs. The bulbs with 2 leaves had the highest ratio of propotion as 75.1% of share among the distribution of bulbs with completely developed leaves and 1 leaf-bulbs and 3 leaves-bulbs had 19.6% and 5.3%, respectively. Also the 2 or 3 leaves-bulbs indicated the better growth states in the part of shoot and bulbs than 1 leaf-bulbs, and there was a significant defferences in each growth between 2 leaves-and 3 leaves-bulbs. On the wild garlics we cannot find out insect injuries. However, there was deseases with symptoms of leaf-spots and lesion from May to June. At first it made a small spots on the leaves, followed by senescence at arrounding area of spots, and then it expanded to whole leaf. This pathogenic bacterium was supposed to be a member of Aristastoma. The contents of crude protein, fat, and carbohydrate in each portion of wild garlics decresed in the order of shoot, expanded leaves and bulbs. On the contrary, crude fibers increased in the same order and so it is not suitable for human consumption nutritional value. However, because the shoots of wild garlics have more than the other Allium sp., the shoots will be a good quality food stuff.

산마늘의 군락지내의 식생, 토양조건 및 병충해 등의 생육환경 그리고 식품영양가를 분석하였다. 자생지의 산마늘은 실생 $3{\sim}4$년 성장되어야 성구로 발육됨을 알 수 있었고, 군락지내의 인경분포는 2엽구가 75%로 가장 많았고 1엽구(19.6%), 3엽구(5.3%)순으로 적었다. 엽수별 생육차이를 보면 1엽구 보다 $2{\sim}3$엽구가 지상부 및 인경의 생육이 좋았으며, 2엽구와 3엽구간에는 차이가 없었다. 산마늘에서는 반점병만 발생하였고 해충의 피해는 없었다. 병징은 5월부터 6월까지 발생하며, 잎에 먼저 반점의 병반을 형성하여 병반의 주위가 황화하기 시작하면서 잎의 전면에 확대 되어 건전주보다 빨리 고사하였지만, 지하부에는 피해를 주지않았다. 병원균은 불완전 균류에 속하는 Aristastoma속으로 추정되었다. 인경 부위별 단백질, 지방 및 탄소화물의 함량은 맹아, 전개엽, 인편의 순으로 감소하였으나 섬유소함량은 그 반대로 증가하여 인편은 식용할 수 없음을 알 수 있었다. 산마늘은 대체적으로 타의 식용 Allium속보다 식품 성분함량이 풍부하여 식품 가치가 높은 것으로 나타났다.
