During imbibition and germination of rape seeds in darkness over 72 h, activities of ascorbate peroxidase, monodehydroascorbate reductase, glutathione reductase and catalase increased significantly, especially during radicle emergence (24-48 h), but dehydroascorbate reductase (glutathione dehydrogenase (ascorbate)) activity showed an overall decrease. Ascorbate content of seeds increased during germination.
