Effect of Hormones on Embryo After-Ripening of Panax ginseng G. A. Mey. Seeds

Li Xian-en, Chen Ying and Zhang Jun   

Abstract: Panax ginseng C. A. Mey seed has a deep dormancy for the morphologica and physiological after-ripening of embryo. This paper described the changes of some enzymic activities and of soluble-protein content during after-ripening of seeds, in the first stage of morphological after-development the activities of amylase, peroxidase and catalase increased gradually, whereas the soluble-protein content decresed rapidly. A high level of enzymatic activities and increasing protein content were also observed, indicating vigorous metabolism in physiological after-ripening of seeds. Hormone treatment increased the activities of the above-mentional enzymes, promoted the development and differentiation of embryo, causing the time of seeds germination one year earlier than that of untreated ones.

Key words: Seed of ginseng, After-ripening, Amylase, Peroxidase, Solule nrotein
