Effects of basal culture medium, sucrose concentration, natural extracts and phytohormones on protocorm differentiation were studied.

试验了基本培养基、蔗糖浓度、天然提取物以及植物激素对铁皮石斛原球茎分化的影响。

youdao

Low level of sucrose is required during induction of Protocorm Like-Body and shoots differentiation.

类原球茎诱导分化过程中所需的蔗糖浓度相对较低。

There were many different reports on the multiplication and differentiation of protocorm and the choice of culture media, but they need further test and verify in practice.

原球茎的增殖、分化与培养基的选择有不同的结论，需要作进一步验证。
