Abstract
The experiment was conducted to study on the germination of seeds, and chemical change in the endorsperm and embryo of maize seeds treated with gibbrellic acid(GA) 25, G A 50, bengyl adenine(BA) 100 and B A 200 ppm. Obtained results can be summerized as follows: 1. The germination rate in the initial stage of maize seed increased most with G A 25 ppm treated but decreased most with B A 200 ppm treatment amount other treated blocks. There is no significant difference between treatments in the middle and later stage of the seed germination. 2. The quantity of Q
GA25, 50ppm과 BA100, 200ppm을 옥수수 종자(種子)에 처리(處理)하여 발아율(發芽率) 및 호흡량(呼吸量)과 배유양분(胚乳養分)인 환원당(還元糖), 전당(全糖), 조단백질(粗蛋白質)의 이동(移動)에 대(對)하여 구명(究明)하고자 행(行)한 실험(實驗)에서 다음과 같은 결론(結論)을 얻었다. 1. 초기(初期)의 발아율(發芽率)은 GA 25ppm구(區)가 가장 높았고 BA 200ppm구(區)가 가장 낮았다. 중후기(中後期)의 발아율(發芽率)은 각(各) 처리구간(處理區間)의 차(差)가 크게 인정(認定)되지 않았다. 2. 호흡량(呼吸量)은 각구(各區) 공(共)히 발아(發芽)와 병행하여 현저히 증가(增加)되었으나 처리구(處理區)가 Control에 비(比)해 Q
