Fluctuation of ATP Content in Soybean and Mungbean Seeds with Germinating Time

콩(Glycine max Merrill) 및 녹두(Phaseolus radiatus L.) 종자의 발아일별 ATP 함량변화

ATP contents of soybean(Glycine max Merrill) and mungbean (Phaseolus radiatus L.) seeds being germinated with Hoagland solution at $30^{\circ}C$ for 6 days were determined. In pregerminated seed, ATP contents in soybean and mumgbean were 11.4 and 63.0$\mu$g/g fresh seed respectively. During germination, the highest ATP content of soybean seeds was 550% of initial content on 2nd day and that of mungbean was 480% on 1st day after germination. ATP content in cotyledon of soybean and mungbean were increased up to 4th and 1st day after germination respectively, thereafter both were decreased, but those in the root, including the hypocotyl, of both seeds were continuously increased with germination progress.
