Panax ginseng C.A. Mey seed has a deep dormancy for the morphological 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 decreased 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-mentioned enzymes, promoted the development and differentiation of embryo, causing the time of seeds germination one year earlier than that of untreated ones
