韓國産 몇가지 무우品種에 對한 生長解析 = Growth Analysis to the Selected Korean Radishes

국문 초록 (Abstract)

本 試驗은 몇가지 韓國産 무우品種을 供試하여 이들의 生態的인 反應을 生長解析法을 利用하여 檢討하므로써 適正栽培法 및 品種改良을 爲한 基礎資料를 얻기 爲하여 遂行한 結果를 報告한다.
1. 葉面積指數는 發芽後 繼續 增加했고 진주대평무우가 0.34㎡/㎡로 가장 높게 나타났으며 알타리무우가 0.20㎡/㎡로 가장 낮게 나타났다.
2. 最大個體生長率은 2.29g/㎡/day였고, 미농조생무우와 太白무우가 他 品種보다 높게 나타났다. 이들 값은 穀類作物의 個體生長率보다는 훨씬 낮게 나타났다.
3. 純同化率은 生育初期에 높게 나타났고 生育後期에는 낮게 나타났으며 太白무우와 쥐꼬리무우는 Water Stress와 같은 不適環境條件에 대한 適應力이 높은 것으로 나타났다.
4. 相對生長率은 純同化率과 同一한 傾向이었다.
5. 葉面積重量比에서 쥐꼬리무우와 太白무우가 他 品種보다 낮게 나타나 葉이 두꺼워짐에 따라 乾物生産能力이 높게 나타났다.
6. 葉面積指數와 個體生長率, 純同化率은 Watson의 法則과 一致했으며 太白무우의 適正葉面積指數는 0.23㎡/㎡이고, 쥐꼬리무우는 0.19㎡/㎡로서 쥐꼬리무우가 더 빨리 適正葉面積指數에 도달했다.

다국어 초록 (Multilingual Abstract)

In order to investigate the suitable cultivating practices and varietal improvement in the selected Korean radishes, the analysis of its growth and statistical observation of its growth functions were carried out means of growth analysis.
The results obtained are summarized as follows;
1. Leaf area index(LAI) was sharply increased after germination. LAI was highest in Jinjudaepyong radish of 0.34㎡/㎡, but in Altari radish was shown to be the lowest of 0.20㎡/㎡.
2. Maximum crop growth rate (CGR) was 2.29g/㎡/day. Minongjoseng and Taebaek radish were high than the other cultivars. These values were by far lower than those of gramineous crops.
3. Net assimilation rate (NAR) was high in early stage and low in late stage of growth Tabaek and Juikory radish were considered to be more adaptive to unfavorable conditions, especially in water stress.
4. Relative growth rate (RGR) was shown to the same trend with NAR.
5. In specific leaf area (SLA) Juikory and Tabaek radish were lowered than the other cultivars so that the dry matter production showed increases according as the leaf became thicker.
6. The relationships between LAI and CGR, NAR was agreed to the watson's law. Optimum leaf area point(LAI opt.) of Taeback radish was 0.23㎡/㎡, and Juikori radish was 0.19㎡/㎡. Accordingly, Juikori radish was reached at the optimum leaf area point rapidly.
