콩 종피의 형태적 특성과 호분층 세포의 효소활성 연구
Morphological Characteristics of Seed Coat and Enzyme Activity of Aleurone Layers in Soybeans

콩종피의 구조적 특성을 전자현미경과 광학 현미경으로 각기 관찰하였고 발아초기 수분흡수 단계에큰 가수분해효소의 활성, 배출 경로와 이에 대한 GA
Soybean seed coat consisted of three layers, and the aleurone layer was attached to the innermost part of seed coat. It showed the different morphological characteristics with single cell layer compared with many cell layers in barley aleurone layer. The structural difference in aleurone cell among varieties was not detected in this experiment. The hole of middle part of hilum consisted of net formed material in order to pass water and gas. In the experiment, it was not studied whether the varieties with hard seed consist of the same structure or not, but the detailed study on this would be necessary. The activity of acid phosphatase showed a tendency to increase in process of imbibition in distilled water. There was no significant difference in the enzyme activity among the varieties tested, but the enzyme activity of Danyoupkong was slightly higher than that of Hwanggeumkong. In germinability, Danyoupkong is higher than Hwangkeumkong, so it might be attributed to the higher activity. There was no difference in acid phosphatase activity between released from the aleurone cell and accumulated in the aleurone cell from 6 to 12 hours incubation of the medium in the absence of GA
