| Abstract: | In this paper are studied the changes in peroxidase isozyme activity and soluble protein content during culture for cotyledon of Chinese cabbage Brassica campestris in vitro.It has been found that with the dedifferentiation and redifferentiation in the course of culture,peroxidase isozyme activity tends to rise and peroxidase isozyme bands tends to increase--a phenomenon which indicates that there is a colse correlation between morphological change and physiological change.Also,it has been found that the addition of AgNO 3 to the culture stimulates peroxidase isozyme activity and promotes the growth of the adventitious bud. |
