Studies On Effect Of Use AMF In Micropropagated Plantlets Transplant

In order to estimate the effects of different arbuscular mycorrhizal fungi (AMF) species, isolates, and select efficient isolates used micropropagated plantlet transplant, the effect of 7 AMF isolates on growth of micropropagated plantlets of Forsythia koreanna 'SauonGold', Hostaplantaginea, Anthurium andreanum are investigated under greenhouse condition.The results show that inoculation the micropropagated plantlet with AM fungi can promote the growth and increase survival rate. Among the isolates used in the investigation , 1# 2# 7# isolate can be used as efficient isolate in micropropagated plantlet transplant.The isolate's inoculation effectiveness is affected by the ecotype. The efficient isolate is originated from where the climate is similar with the microclimate of the greenhouse.The isolate with higher colonization rate also has better incolation effectiveness. The efficient isolate should have the ability of quick colonization and maintaining the relativehigh colonization rate in a long period.The result of inoculating Glomus mosseae spores to the Forsythia koreanna 'SauonGold' under sterile condition show that the spores' germination rate increases with the pH of the medium range from 5.8 to 7.0. Light has no harmful effect on the germination of the spores. And the isolate can colonize the Forsythia koreanna 'SauonGold' in vitro normally.
