以脱脂棉、琼脂、蛭石、河沙、壤土为支持物,在1/2MS+NAA1.0mg/L+6-BA0.5mg/L培养基上对地灵试管苗生根情况进行了分析。结果表明,支持物对地灵的生根有明显影响,在珍珠岩、琼脂和脱脂棉中地灵的生根率均达到100%,各处理之间差异不显著;生根质量以珍珠岩中最优,幼根能产生大量多级分枝,形成较为强大的根系,且不同支持物试管苗的移栽结果也表明,珍珠岩在地灵试管苗生根中是琼脂的理想替代物。
The rooting of Dionysus mongolica seedlings was studied with 1 / 2MS + NAA1.0mg / L + 6-BA0.5mg / L medium with absorbent cotton, agar, vermiculite, sand and loam as support. The results showed that the support had significant effect on the rooting of Gypsophila. The rooting rate of Ghost in pearlite, agar and absorbent cotton reached 100%, with no significant difference among the treatments. The rooting quality was the best among young perlite Roots can produce a large number of multi-level branches, the formation of a more powerful root system, and the transplanting of different support tube seedlings results also show that perlite in the root of Guling seedlings is an ideal substitute for agar.
