Abstract

Radish and Chinese cabbage were cultivated under hydrophonic culture to investigate the effect of chromium on germination, cell elongation, ${\alpha}$-amlyase activity, contents of chlorophyll and protein. With increasing concentration of cromium, germination, cell elongation, ${\alpha}$-amlyase activity were decreased in both radish and Chinese cabbage, the rate was higher in radish than in Chinese cabbage. Contents of chlorophyll a and b were also decreased and chlorophyll a was higher than chlorophyll b. As the concentration of chromium was increased inhibited in the order of protein> ${\alpha}$-amylase activity>chlorophyll a>chlorophyll b.

크롬에 의한 무와 배추 유식물의 생리학적 반응을 조사하기 위하여 수경재배 조건하에서 크롬용액의 농도에 따른 무와 배추종자의 발아율 세포신장, ${\alpha}$-amylase활성도, 엽록소, 단백질함량의 차이를 비교하였다. 크롬처리농도가 증가함에 따라 농도의존적으로 무와 배추종자의 발아율, 세포신장, ${\alpha}$-amylase 활성도가 감소하였는데 배추에서 보다 무에서 그 저해정도가 심하게 나타났다. 무와 배추에서 크롬처리시 약간의 chlorophyll 함량 감소가 있었으며 chlorophyll a가 b보다 더 저해를 받았다. 크롬농도 증가에 따른 ${\alpha}$-amylase 활성도, chlorophyll a와 b, 단백질함량과의 관계를 다중회귀분석한 결과 단백질> ${\alpha}$-amylase>chlorophyll a>chlorophyll b의 순서로 저해를 받았다.
