Określono status mikoryzowy Miscanthus х gigantem Greef et Deuter - azjatyckiego gatunku wieloletniej trawy uprawianej obecnie do celów energetycznych. Miskanta uprawiano na terenie zanieczyszczonym Cd, Zn i Pb w Bytomiu oraz na poletku kontrolnym w Katowicach. Na wszystkich poletkach badawczych w korzeniach miskanta stwierdzono obecność struktur typowych dla mikoryzy arbuskularnej. Nie zaobserwowano różnic w poziomie kolonizacji mikoryzowej pomiędzy poletkiem kontrolnym a poletkami zanieczyszczonymi metalami. Kumulacja Cd, Zn i Pb w pędach i korzeniach miskanta rosła wraz z ich całkowitą zawartością w glebie. W większości przypadków wyższe zawartości metali odnotowywano w korzeniach niż w pędach.

Miscanthus х giganteus Greef et Deuter, is a large bunch grass, originating from Asia, which have the potential for very high rates of growth. Miscanthus crops could be successfully grown on contaminated land. Although some Miscanthus species e.g. M. sinensis and M. florodulus were described as mycorrhizal [Ma et al. 2006; Leung et al. 2007] the present investigation is the first one to demonstrate the characteristic of Miscanthus х giganteus mycorrhiza from an area contaminated with Cd, Zn, and Pb. Roots for mycorrhizal studies were collected from contaminated site in Bytom and from control non-contaminated plot in Katowice. Metal concentrations in soil and plants roots and shoots were also examined Arbuscular mycorrhizal structures were described in plant from both heavy metal polluted and control plots. Mycorrhizal colonization level of Miscanthus х giganteus in the place with the highest content of metals in soils was not different from that observed in the control plot. Cd and Zn were mostly accumulated in the roots but by contrast Pb concentrations were found to be higher in shoots. Our results clearly demonstrated that alien for Polish flora grass species Miscanthus х gigantem really formed arbuscular mycorrhizal association in soil contaminated with of Cd, Zn and Pb.
