Abstract: Effects of 3 disinfectants(1∶150 84, 0.1% HgCl2 and 10% H2O2) and 3 times on rate of germination, contamination and growth index(GI) of Cichorium intybus were researched with orthogonal design and influence on seedling of C. intybus cv. puna. All factors had the most significant effects on germination; disinfectants and sterilizing time had more significant effects on contamination frequency and germination index of C. intybus, but varieties of C. intybus is not significant frequency. 0.1% HgCl2 had the most significant disincentive effect to C. intybus cv. puna. Above all the best method of building aseptic plant of C. intybus is 10% H2O2 immersing 10 min.
