Effects of Light on the Pigment Production and Chloroplast Development of Ginseng Hairy Roots
초록
The effects of light on the pigment production and chloroplast development were examined on ginseng hairy roots cultured in 1/2MS liquid medium. The chlorophyll and carotenoid production were increased from 1,000 to 3,500 lux condition, but decreased drastically in 7,000 lux condition. The anthocyanin production was significantly increased with increment light intensity(1,000∼7,000 lux). The thylakoid membrane of chloroplast was proplastid in dark condition and it began to develop into thylakoid membrane in 1,000 lux condition and then intact thylakoid membrane was developed in 3,500 lux condition. However, the development of thylakoid membrane in 7,000 lux condition was inhibited comparing to 3,500 lux condition. The total chlorophyll production in blue light condition were high comparing to other wavelength and same as 40% of total chlorophyll on white light(3,500 lux) condition. The chlorophyll and carotenoid production by sucrose concentration were high in 3% sucrose condition and anthocyanin production was high in 4% condition. The production of chlorophyll and carotenoid by light periods was high when explants were cultured in dark condition for 1 week and then transferred to light condition for 4 weeks. Our results suggest that pigment production and chloroplast development could be accelerated by light Intensity of specific wavelength in cultures of ginseng hairy root.
