우리나가 58個 마늘 주산단지에서 生態型에 따른 生育과 收量에 對하여 1982∼1984년 까지 3年동안 調査硏究한 바 다음과 같은 結果를 얻었다. 1. 暖地型의 播種期는 9月 20日前後였고 寒地型은 10月20日前後였다. 2. 坪當栽植株數는 暖地型이 坪當 100株寒地型이 123株였다. 3. 우리나라 마늘의 出葉期는 暖地型은 越冬前, 그리고 寒地型은 2月初旬 이후인데 內陸地方일수록 늦었다. 4. Multiple regression分析에 따르면 收量에 미치는 草長의 影響을 寒地型은 6月 30日, 暖地型은 11月30日의 초장이 收量에 가장 큰 影響을 미쳤다. 마늘의 草長과 收量과의 關係式은 다음과 같다. 暖地型收量 : Y=571.6+8.34X(X=11月 30日 草長) 寒地型收量Y=251.8+5.45X(X=6月 30日 草長) 5. 葉數는 收穫期까지 증가했으며, 수확시 난지형은 약 10매, 한지형은 8매였다. 收量과 葉數와의 관계를 보면 寒地型은 6月 20日경, 그리고 暖地型은 1月 20日의 葉數가 收量과 밀접한 관계가 있었다. 6. 枯葉率은 暖地型에서는 1月 30日과 5月 30日에 높았고, 寒地型은 6月에 높았다. Multiple regression에 의해 枯葉率과 收量과의 關係를 보면 暖地型은 1月의 枯葉率의 影響이 그리고 寒地型은 6月 收穫에 큰 影響을 줬다. 7. 우리나라 主産團地의 10a 當 收量은 暖地型이 771㎏, 그리고 寒地型은 652㎏이다.

The major objectives of this study were to find out the growth and yield of two ecotypes of Korean garlic in main garlic producing districts in Korea. The data were collected by the field survey which had been conducted at 270 township in 58 major garlic production countries throughout the country on 10th, 20th, and 30th day of every month from 1982 to 1984. The results of this study were as follow: 1) Sowing period of garlic of southern and northern ecotype were around September 20 and October 20, respectively. 2) Average number of plants per 3.3㎡ of the southern and northern ecotype were 123 and 100, respectively. 3) Leaf emergence time of southern ecotype was before the beginning of winter (November) and that of northern ecotype was from early February till April. 4) Stepwise multiple regression analysis showed that the plant heights measured on November 30 for southern ecotype and on June 30 for northern ecotype most adequately predicted the yield of garlic. The relationship between yield and plant height were as follows: Southern ecotype; Y=571.56+5.34X Northern ecotype; Y=251.81+5.45X where Y is yield expressed in ㎏/l0a and X is height in cm at the respective date. 5) The number of leaves increased until harvest in both ecotypes. At harvest, the number of leaves in southern and northern ecotype were 10 and 8, respectively. Number of leaves counted on January 20 for southern ecotype and on June 20 for northern ecotype correlated best with the yield of the ecotypes. 6) The highest senescent portion of southern ecotype and northern ecotype were seen on January 30 and May 30, respectively. Stepwise multiple regression analysis showed that the senescent portion of southern ecotype counted on January 30 and that of northern ecotype on June 20 mostly affected the yield. 7) Average yield of southern and northern ecotype at the main garlic producing districts were 771 and 652㎏/10a, respectively.
