Abstract

In this paper, the roles of type and concentration of enzymes on protoplast isolation from in vitro leaves, multi-scalps (highly proliferating meristem culture), and young male flower of banana cv. cau man were studied. Respiration rate and content of plant hormones of these materials were analysed. Different techniques were used to culture these protoplasts. The development of protoplasts was observed under fluorescence microscope. The highest yield of protoplast (69.5 x 106 protoplasts / g fresh weight) was obtained from young male flowers after 16 hours treatment with 1.5 % cellulase, 0.25 % pectinase and 0.25 % hemicellulase. The combination of hanging drop cell technique (in 6 days), and carrot feeder layer cells in N6PKM medium supplemented with 0.2 mg/L 2,4- dichlorophenoxyacetic acid (2,4-D), 1 mg/L α- naphthalene acetic acid (NAA), and 0.5 mg/L zeatin are suitable for protoplast development. Protoplasts that were isolated from multi-scalps and young male flowers created the wall and divided when cultured by this method. The development of protoplasts from young male flower began with cell walls creation after 4 days, the cell division was after 6 days, and small colonies formation was after 28 days of culture. The differentiation and physiological activity of cells play an important role on quantity and quality of protoplasts, as on the well as protoplast development.
