Objective:In order to screen for suitable host plants for Malania oleifera,five species were planted with M.Oleifera through a pot experiment.Methods:The height,collar diameter,biomass,haustoria number and size,chlorophyll content,content of nutrient elements in roots,stems and leaves were examined.Results:Eighteen months after experiments,it was found that the growth of M.oleif-era exhibited significant differences among treatments of the host plant species.Alnus nepalensis was the most efficient host,the height,collar diameter and aboveground biomass of M.oleifera were 72.92 cm,9.83 mm and 33.57 g,which were 1.89 times,1.45 times and 3.19 times of the control without host.Next came Eupatorium capillifolium,the height,collar diameter and aboveground biomass of M.oleifera were 57.55 cm,8.66 mm and 22.49 g,achieved 1.49 times,1.28 times and 2.14 times of the control.The chlorophyll content and the content of total nitrogen,total phosphorus and total potassium of M.Oleifera grown with A.nepalensis and E.Capillifolium were significantly higher than other treat-ments.Conclusion:Suitable host plants promoted the absorption of M.Oleifera for nutrients,en-hanced its chlorophyll synthesis,and thus improved the growth,indicating the obvious dependency of M.oleifera on the hemiparasitism.A.nepalensis and E.capillifolium could be applied as ideal host plants for the cultivation of M.Oleifera.
