초록

산달래 자생특성을 전국에 걸쳐 조사하고 이들을 대상으로 생태 및 형태적인 주요형질을 검토하여 우량종의 선발과 아울러 육종과 재배에 필요한 자료를 얻고자 연구를 하였다. 자생지의 광환경은 303개의 자생지 중에서 양지는 194개인 64.0%로 가장 많았고, 반음지는 96개인 31.7%로 다음이었으며, 음지는 13개인 4.3%로 가장 적었다. 자생장소는 밭 주변 51.2%, 사찰 주변은 18.8%, 산 11.6%, 도로변 7.9%, 하천변 5.9%, 논 주변이나 해안 2.3%의 순이었다. 자생지는 $33^{\circ}N{\sim}38^{\circ}N$, $126^{\circ}E{\sim}130^{\circ}E$ 범위의 모든 지역에 널리 분포하였다. 자생양상은 개체 간에 1~10 m의 간격으로 군생하였으며 모구 주위에 3~5개의 자구가 있었다. 생육은 자생지역에 따라 차이가 있었으나 대체로 맹아기는 9월에 시작되어 익년의 3월까지이었다. 추대기는 5월이었고, 그 양상은 주아만 착생하는 것이 59.2%, 꽃과 주아가 혼생하는 것이 24.7%, 그리고 꽃만 착생하는 것이 16.1%로 3유형이 있었다.

This study was carried out to develop the breeding and cultivation of Allium grayi by investigating its natural habitats in Korea. The number of sunny, half-shady, and shady natural habitats were 194 (64.0%), 96 (31.7%), and 13 (4.3%), respectively. Natural habitats included upland (51.2%), Buddhist temple (18.8%), mountain (11.6%), roadside (7.9%), river (5.9%), paddy field (2.3%), and seashore (2.3%). Natural habitats ranged widely in all areas between $33^{\circ}N{\sim}38^{\circ}N$ and $126^{\circ}E{\sim}130^{\circ}E$. Self-generation patterns included growing spontaneously with a 1~10m distance between plants, and there were 3~5 bulbils around each bulb. The sprout stage began in September and continued until March of next year in natural habitats. The bolting period was May, with the following three patterns: tuber (59.2%), flower and tuber (24.7%), and flower (16.1%).
