Abstract
The white and red calli were isolated from the callus of the stem explants of potatoes (Solanum tuberosum cv.Chieftain).The effects of growth regulators,antibiotic and sucrose on callus growth and anthocyanin content in callus cultures were studied by measurement of fresh weight and spectrophotometric assays.The results indicated that the lower contents of 2,4-D promote accumulation of anthocyanins in red callus.The higher contents of 2,4-D stimulate callus growth and inhibit anthocyanin production in red callus.The higher contents of 6-BA promote accumulation of anthocyanins in red callus,induce anthocyanin production in white callus and inhibit callus growth.The white callus can be induced to turn red and accumulate anthocyanins by different concentration of kanamycin.The higher contents of kanamycin inhibit callus growth and turn brown to lead callus dead eventually.The elevated contents of sucrose can stimulate anthocyanin production,while more than 70 g/L inhibit callus growth.The results of this study have laid the foundation for the investigation of the control mechanism of anthocyanin biosynthesis and colorant production in a factory by setting an efficient tissue culture system in the future.
