APPLICATION OF "UNIFORM DESIGN" TO STUDY THE EFFECTS OF ELECTRIC FIELD STIMULUS AND SEVERAL CULTURAL FACTORS ON DIVISION FREQUENCY OF PROTOPLASTS DERIVED FROM CABBAGE (BRASSICA OLERACEA L. VAR. CAPITATA) LEAVES

Uniform design, a new test design method, was adopted to evaluate and study the effects of electric field stimulus and other four factors in culture on the division frequency of protoplasts of cabbage (Brassica oleracea L. var. capitata). Of the 10 treatments in the study, No.9 was optimum in respect of cell division. Analysis of regression pathway indicated that the orientation and strength of the electric field strongly affected cell division and that other factors in the culture media influenced cell division frequency directly or indirectly. The results showed that uniform design was effective in screening optimum cultural conditions, including various media for plant protoplast culture and in evaluating the effects of various factors in the media on cell division frequency by analysis of regression pathway.
