The first type is the chaining colony, between the colony does not have the obvious demarcation line, these colonies are work as when agar-agar and experiment mix, a zoogloea is dispersed the result; The second type is the water film type colony which forms between the agar-agar and the plate bottom; The third kind is the water film type colony which forms in the plate edge or the agar-agar surface.

第一种类型是链状菌落，菌落之间没有明显界线，这些菌落是当琼脂和试验物混合时，一个细菌块被分散所致；第二种类型是在琼脂和平皿底之间形成的水膜样菌落；第三种是在平皿边缘或琼脂表面形成的水膜样菌落。

The results showed that the growth of root tips in liquid medium was better than that in agar-solidified medium and solid-liquid two phase medium, for that increasing agar concentrations in medium will reduce the root growth; darkness was beneficial for Fraxinus mandshurica root tip culture in vitro; as the carbon sources, sucrose was better than glucose and maltose as the carbon ...

结果表明，不添加琼脂的液体培养基对根尖的生长较添加琼脂的固体培养基和固—液培养基好，原因是增加琼脂的量会抑制根的生长；暗培养比光培养更有利于水曲柳离体根尖的培养；蔗糖作为碳源的效果较果糖和麦芽糖好，其中以3%的蔗糖对离体根尖的生长效果最好。
