In spring 2013, the author conducted experiments on studying the effects of different types of cuttings in the propagation of natural food colour plants. The results showed that colour plants had strong capabilities in regeneration, were able to be propagated from different types of cuttings with high survival rate (from 77.3 to 97.3 percent), yields of cuttings had no difference (plants producing red dye gained from 8.18 to 10.15 tons/ha, plants producing purple dye obtained from 6.27 to 6.93 tons/ha). In which, plants producing red dye had stronger capabilities in regeneration than ones producing purple dye, the germination of different plant cuttings was more than 90 percent, strong growth shoots capabilities, branching level 1 was more and higher productivity than plants producing purple dye.
