Kinetin (6-Furfurylaminopurine)의 엽면살포가 상수의 생장 및 생체내 대사에 미치는 영향 (II)

The effects of foliar spray of Kinetin (6-Furfurylaminopurine) on the growth of mulberry tree and the metabolic activities in the leaves were measured. The results of this experimented are summarized as follows: 1. Foliar application of Kinetin was effective in increasing of leaf area, the fresh and dry weight of the leaves, the length and diameter of shoots. 2. Chlorophyll content was generally increased in all treated leaves. 3. All the treated leaves were higher in GOT activity than the control leaves but were lower in GPT activities. 4. The activities of the carbohydrate metabolism in the mulberry leaves were higher than that of the control in all treated leaves.

Kinetin의 엽면살포가 상수의 생장및 생체내 대사에 미치는 영향을 분석 검토하여 얻어진 결과를 요약하면 다음과 같다. 1. 상엽의 생건중, 엽면적. 지조장, 지조경의 증대에 효과가 있었다. 2. 상엽의 엽록소의 함량증대에 효과가 있었다. 3. 상엽의 GOT활성은 촉진시켜 주었으나 GPT활성에는 영향을 주지 않았다. 4. 상엽내 당대사를 촉진시켜 주었다.
