摘要
利用正交设计研究了1∶150 84、0.1%HgCl2和10%H2O23种消毒剂和3个不同消毒时间对不同菊苣种子发芽率、污染率和发芽指数的影响,并对普那菊苣幼苗生长的影响进行了研究,结果表明,3个因素对发芽率影响差异都极显著;消毒剂种类和消毒时间对污染率和发芽指数影响差异显著,品种对污染率和发芽指数影响差异不显著;0.1%HgCl2对普那菊苣生长抑制作用最明显。综合各因素确定,10%H2O2消毒10 min是菊苣最佳消毒方式。
Effects of 3 disinfectants（1 ： 150 84, 0. 1% HgCl2 and 10% H2O2） and 3 times on rate of germina tion, contamination and growth index（GI） of Cichorium intybus were researched with orthogonal design and in fluence on seedling of C. intybus cv. puna. All factors had the most significant effects on germination; disin fectants 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 toC. intybus cv. puna. Above all the best method of building aseptic plant of C. intybus is 10% H2O2 immersing 10 min.
