Abstract
The wavelength range that activates betalain pigmentation has been studied following selection of light induelble betalain producing callus lines originating from Portulaca sp. ‘Jewel’ seedlings. Light sources with different wave-lengths were used to irradiate the callus, resulting in blue light being effective in inducing betalain pigmentation. In addition, when UV light was combined with blue light, some calluses from this cell line showed high production of the pigment. This is a first report that betalain pigmentation in callus was induced by blue and blue/UV lights.
