국문 초록 (Abstract)

Celery種子는 發芽期間이 길고 高溫期에는 發芽가 不良하고 特히 暗黑상태에서는 發芽率이 극히 떨어지는 菜蔬인데 BA를 處理 함으로써 發芽促進의 效果와 實用化를 究明코저 BA를 濃度別로, Celery 品種 Cornel 619號에 處理하여 試驗한 結果는 다음과 같다.
1) 發芽床處理에서는 5ppm까지는 對照區 보다 發芽率, 發芽勢가 增加되었고 平均發芽期間도 短縮되었다.
2) 2時間 浸淸處理 試驗에서는 光條件 暗黑상태 모두 낮은 濃度에서 發芽率, 發芽勢가 增加 하였으나 平均發芽期間은 오히려 濃度가 높을수록 增加하는 傾向을 보였다.
3) 1時間浸淸處理와 30分處理 試驗에서 光條件下에서는 濃度가 높을수록 發芽率, 發芽勢가 떨어졌으며 平均發芽期間은 濃度間에 差異가 없었으나 對照區보다 促進되었다. 暗黑상태에서는 濃度間에 差異가 없었다.
4) 以上의 結果로서 BA發芽床處理나 1時間, 30分浸淸處理로서 高溫期와 暗黑상태에서 發芽를 促進시킬 수 있으리라 생각되었다.

In the view of difficulty in seed germination of Celery during the high temperature season and in the dark condition, a study was conducted with N6-benzladenine(BA) to investigate any promote influence of the germination of celery var. Cornel #619 seeds and its practical value when applied at various concentration.
1. The seed-bed treatment of the 5 ppm or its low levels of BA showed promoted germination of seeds and shortened mean number of days necessary for germination.
2. When the Celery seed was dipped in BA at the lower and higher Concentration, it was found that BA increased both germinating percentage and also advanced germinating speed.
3. When seed was dipped for 1 hour and 30 minute in the higher concentration of BA both germinating percentage and speed of germination decreased. There was no relationship between BA concentration and germination time, However germination was more advanced than in the control.
4. The result show that dipping speed for 30 minute and 1 hour not only restores slow germination in this country but also has possible practical uses in promoting germination of Celery seed in dark conditions.
