Effect of Coconut Milk and Rare Earth on Proliferation, Rootage and Isozymes of Dendrobium in Tissue Culture

摘要：

In tissue culture, effects of coconut milk, rare earth and medium on proliferation, rootage and isozymes of Dendrobium were studied. The result indicated that coconut milk and RE could promote proliferation and rootage, with their combined treatment the most effective. In proliferation culture, coconut milk enhanced peroxidase (POD) and esterase (EST) activity and types, RE decreased POD, but increased EST activity and types and combined treatment did not show the same influence on POD and EST too. In rootage culture, adding coconut milk decreased POD activity, but improved EST activity in 1/2MS medium and declined EST activity, expression type in WPM medium, when using RE, POD and EST activity both reduced, types of the former decreased, types of the latter changed slightly with the basic medium. And combined treatment would decreased POD activity and types.
