摘　　要：以满天星试管苗的茎段为外植体,采用MS基本培养基,附加1.0mg/L的6-BA,建立满天星的无菌植株,以继代增殖培养后的单株为材料,研究营养液中pH和EC对试管苗水培生根的影响。结果表明:对满天星幼苗生长和生根的营养液以pH 6处理的幼苗生长及根系发育最佳;高EC浓度较适合满天星的瓶外生根,EC值应调节为2.5mS/cm。Taking the stem segments of Gypsophila paniculata L.as explants,on the MS basic medium with 1.0 mg/L 6-BA,established system of Gypsophila paniculata L.sterile plant,proliferation culture of a single plant as the material pH and EC influencing factors were studied.The results showed that growth of shoots and roots were best in pH 6 in nutrient solution;high EC concentration was suitable for ex vitro rooting,EC value should be adjusted to 2.5 mS/cm.
