葡萄에 對한 Gibberellin의 反應 및 環狀剝皮에 依한 熟期促進에 關한 試驗
朴與燮 全南大學校 農漁村開發硏究所 1965 農業科學技術硏究 Vol.3 No.-
The experiments were made to know the increase of berries, the promotion of harvest time, and the prevention of transpiration of water in berries after harvest by the application of 100 ppm gibberellin at 25 days after blooming in Ontario and Campbell early and 10 days after blooming in Golden muscat and Black humburg. In the addition of Buffalo and Steuben to varieties mentioned above except Black humburg, the ringing was made in order to excellerate the harvest time. The increase of berries was shown in Ontario and Campbell eary by dipping the berries at 100ppm of gibberellin 25 days after blooming, and the seedless berries were not made. The increase of berries was not shown in Golden muscat and Black humburg by dipping at 100 ppm of gibberellin 10 days after blooming but the seedless berries were made partially and the harvest time was not unique in the same lunches, producing some of seedless berries in the bunches. The weight of seedless berries was decreased as compared with the seeded berries. The ringing on 10th of July in Ontario, Campbell early, Buffalo, Golden Muscat and steuben brought about a 5 days earlier harvest. In Ontario, the application of gibberellin 25 days after blooming had excellerated the harvest, but in Campbell early it had delayed coloring of the berries. The prevention of transpiration of water in berries was not shown, but petioles and peduncles were hardened by the application of gibberellin and the shape of the bunches was maintained during a long period as compared with the non-treated berries.

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. 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.
