| The enzyme patterns and the food storage changes in radish (Raphanus sativus L. cv. Taewang) cotyledons during seedling development were studied. The radish seeds were germinated for 8 days at $25^{circ}C$ under light (7, 000 lux) or dark condition. The lipid and protein contents per seed were 4.3 mg and 2.85 mg respectively. In 8-day-old light-grown seedling, the lipid and protein contents per cotyledon pair were 1.5 mg and 2.08 mg; in 8-day-old dark-grown seedling, they were 0.8 mg and 1.24 mg respectively. The heterotrophic phase of seedlings continued for 3 days after sowing and followed by autotrophic phase (3~6 day) and senescence phase (6~8 day). The food storage function decreased in response to time course. During heterotrophic phase, the activities of glyoxysomal enzymes (malate synthetase, isocitrate lyase, and catalase) were high at 2~3 day. Those patterns were somewhat more prominent in darkness. During the autotrophic phase, the activities of peroxysomal enzymes (glycolate oxidase and catalase) increased at 4~5 day. |
