Effects of different AMF strains on some physiological indices were studied with Rosa hybrida‘Carola'.AMF strains are Glomus diuphauam,G.etunicatum,G.intraradices,G.mosseae,G.versiforme.The soluble sugar content,N,P, K content and the superoxide dismutase(SOD),peroxidase(POD) and catalase(CAT) activity were measured at stages of young plants and florescence.The results showed that AMF treatments(except G.d) could enhance the soluble sugar content in roots and leaves of R.hybrid.G.d treatment could enhance t...
