为了克服组培快繁满天星移栽成活率低，培养周期长，成本高，条件要求严格等，进行了组培满天星最佳生根方式试验。结果表明：茎尖组织培养的新茎，用生根粉处理后进行扦插水培，其生根率达９０％以上，较试管培养高１６％，较基质扦插高５０％；育苗周期较试管培养和基质扦插缩短约２０ｄ；移栽成活率较试管培养和基质扦插分别提高３５％、８４％。结论：用生根粉处理后进行扦插水培是满天星最佳生根方式。
In order to overcome the problems of tissue culture and rapid propagation, such as low survival rate of transplanting, long period of cultivation, high cost and strict conditions, the best rooting method was studied. The results showed that the stems of the new stems cultured with rooting powder after cutting culture, the rooting rate of more than 90%, 16% higher than the test tube culture, medium cutting 50% higher; seedling cycle than the tube culture and substrate Cuttings shortened by about 20 days. The survival rate of transplanting increased by 35% and 84% respectively compared with that of test tube and substrate cutting. Conclusion: The rooting powder treatment is the best method for rooting of Gypsophila.
