root tip culture meaning in Chinese

根尖培养

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 sources , and 3 % sucrose was best for the root tip growth of fraxinus mandshurica
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。
