摘　　要：通过在培养基中加入不同浓度的糖分、琼脂、细胞分裂素（ＢＡ和ＫＴ）、聚乙烯醇（ＰＶＡ）进行试验研究，发现满天星玻璃苗的数量随着糖分及琼脂浓度增加而减少，但细胞分裂素对玻璃化现象无影响，而聚乙烯醇对满天星玻璃化现象有明显的抑制作用，其最适浓度为２０ｇ／Ｌ。From the experiments of mixing sugar, agar, BA and KT, PVA with different concentrations in the culture medium, we find out that the number of vitrified plants of Gypsophila decreases with the increase of the concentrations of sugar and agar, but BA and KT have not any effect on the vitrification of the plants in vitro of Gypsophila; and PVA has a very obvious inhibition on the vitrification of the plants in vitro of Gypsophila. Among of the treatments, the most suitable concentration is 2.0 g/L PVA.
