摘　　要：随着寄生植物对我国农林业危害越来越来大,寄生植物与寄主间相互作用及物质转运的研究也成为热点。借助先进的ICP-AES技术对寄生植物肉苁蓉及其寄主不同器官中的各种微量元素进行了系统的研究,结果发现肉苁蓉及其寄主中所含主要元素基本相同,但各种元素含量存在一定的差异,其中K,P,Na,Ca元素含量较高,且肉苁蓉中K和P含量高于寄主植物。研究结果为寄生植物合理利用及有害寄生杂草防除提供了新的科学依据。Parasitic plants are destructive agricultural pests.Today,parasitic plants have been recognized as serious pests causing considerable economic damage on crop and woods in China.Parasites are among the most destructive weeds known,and more and more people begin to pay more attention to the relationship between parasitic plant and host.Two cistanches and their hosts were analyzed and characterized by ICP-AES.The contents of K,P,Na,Ca,Mg,Fe,B,Cu,Zn,Al and Mn in Tamarix chinensis,Haloxylon ammodendron,Cistanche deserticola and Cistanche tubulosa were determined.The results showed that the spectra of main elements of the two cistanches and their hosts are similar,but the content of each element is different.The content of K,P,N and Ca is higher than other element,The content of K and P in Cistanche deserticola and Cistanche tubulosa is higher than the content of theirs hosts.The present study provides a new scientific foundation for further study and general application of parasitic plant.
