GA 및 2, 4-D 處理가 洋芹의 生育에 미치는 影響
金正根,朴華性,梁元模 順天大學校 1984 論文集 Vol.3 No.1
This study was conducted to determine the optimum concentration, appropriate treatment times of GA and 2,4-D on the growth and yield under high temperature conditions. Utah 15 was employed and treatment times were 40days, 30days, 20days prior to harvest, hormones levels applied were 10, 50, 100ppm in GA and 1, 5, 10ppm in 2, 4-D 1. Increasing GA concentration increased the plant height, petiole length and leaf area. 20days before harvest was remarkably effective but in the case of 2,4-D increment was observed up to 5ppm and in 10ppm growth inhibitions have occurred. 2. Significant differences were recognized in leaf length and number of petioles as affected by the levels of concentration regardless of treatmentstimes. 3. Yield responses have shown the increase up to 31 percent in 100ppm of GA, 15 percent in 5ppm of 2,4-D compared with control. While treatment between 30 and 40days before harvest no significant differences were observed among the levels of the GA treated. 4. Application with low concentrations of 2,4-D were recommended to increase the yield of celery, especially in 20 days before harvest.
양파 密植栽培에서 멀칭과 솎음이 殘存球肥大에 미치는 影響
金正根,崔成圭,梁元模 順天大學校 1985 論文集 Vol.4 No.1
앙파를 密植被覆栽培하여 生育中에 풋양파솎음程度 및 時期가 殘存個體의 球肥大에 미치는 影響을 究明하고자 試驗을 實施한 結果는 다음과 같다. 가. 生育은 멸칭과 터널이 保溫體果로 無被覆보다 良好하였다. 나. 풋양파 收量은 포기솎음(株)보다는 줄솎음(列)이 增收되는 傾向이었고 作業이 便利하였다. 다. 솎음 후 殘存個體 球肥大는 早期 솎음일수록 促進되어 1株重이 모든 處理間 有意的인 差異가 認定되었다. 라. 球양파 收量은 3月의 早期 풋양파 솎음으로 個體間 無競合 條件에서 肥大를 促進시키므로써 4月의 솎음區보다 增收되었다. 以上의 結果로 보아 양파를 密植被覆栽培 (10x10㎝) 한 後 3月中下旬경 줄(列)솎음후 20x10㎝로 하면 早期 풋양파의 收穫도 할수 있고 6月 上旬의 球양파 收穫도 可能하였다. Thining desree tended to increase fleshiness caused to onion plants by thinning time and mulching. Onion cultiver is applied New Apolo (Allium cepa L.Early group)and planted Oct.26,1983 in the planting density of 20x10㎝, 20x5㎝ and 10x10㎝, respectively. Thinning method experimented;All, Plant and Row thinning were employed and planting densities were adjusted to 20x10㎝ after Soiling onionn thinning. The most effective thinning time was Apr.20plot thinned as soiling onion production. The other side, Mar. 30 thinned plot was more effective in the side of fleshiness and whole onion yield.More whole and soiling onions suitable for early processing were produced in the P.E tunnel plots than in the P.E mulch plots, but for late processing more produced in the P.E mulched plot than in the P.E tunnel. In the thinning distance, row thinned plot war produced better than plant thinned, and thinning labours decreased remakably.

The study was conducted to investigate the culturing method for soft―ening of ginger by regulating the temperature and shading under various tre―atments; black polyethylene film tunnel, transparent polyethylene film tunnel with straw mat covering , transparent polyethylene film tunnel with cloth mat covering, transparent polyethlene film tunnel with chaff mulching. The results are following ; 1. The effects of retaining warmth and shading were higher in the black polyethylene film tunnel and transparent polyethylene film tunnel with cl-oth mat covering than others, and there was 100% shading effect in the la-tter. 2. The degree of softening was increased in order of transparent polyethyle-ne film tunnel with cloth mat covering, black polyethylene film tunnel and transparent polyetlene film tunnel with straw mat covering. 3. There was a tendency to increase a yields in the transparent polyeth-ylene film tunnel with cloth mat covering because the high, width and de-velopment of plant were greater than the other treatments.
