다국어 초록 (Multilingual Abstract)

Effects of salt concentrations on the cell growth and the pigment accumulation were investigated in cell suspension culture of Vitis vinifera and Phytolacca americana L.. The growth pattern of vine cell in control was showed the normal exponential growth pattern, but in the dilution media delay the exponential growth pattern from 4 to 8 days after culture. Maximal accumulation of anthocyanin was observed at 12 days after culture in all treatments. In cell suspension culture of Phytolacca, accumulation of betacyanin occurred in parallel with the cell growth pattern and maximal accumulation of betacyanin was observed after 8 days of culture. In the vine cell culture, the cell growth was showed the peak at 87.6mM of sucrose in the medium and reduced at over this concentration. Maximal anthocyanin accumulation was showed at 146mM of sucrose. In the higher concentrations of sucrose, the cell growth was rapidly decreased, but the accumulation of anthocyanin was not. Otherwise, in case of Phytolacca cell culture, betacyanin accumulation was showed in parallel with the cell growth increased with sucrose concentration. It was suggested that the anthocyanin of vine and the betacyanin of Phytolacca were controlled by different mechanisms.
