Abstract

Effect of different Arbuscular Mycorrhizal Fungi (AMF) on uptake of macro and micronutri-ents by in vitro raised plantlets of chrysanthe-mum cv. Yellow Bangla has been studied. Four AMF strains namely, Acaulospora laevis, Acau-lospora scorbiculata, Glomus fasciculatum and mixed AMF strains (Nutrilink®) were used to screen the suitable AMF strain for micropropa-gated chrysanthemum plantlets. These plantlets showed maximum accumulation of N, P and Ca both in shoots and roots at 90 DAI. Maximum K and Mg accumulation was observed at 60 DAI with the same fungal strain. The predominant effect of mixed AMF (Nutrilink®) was also ob-served in uptake of Fe and Mn at 90 DAI in both shoot and root samples. However, maximum ac-cumulation of Zn was observed in shoots of Glo-mus fasciculatum inoculated plantlets. The ex-periments revealed significant increase of nutri-ent uptake in both shoot and roots in the plant-lets inoculated with mixed AMF strains (Nutrilink®) followed by Glomus fasciculatum inoculated microplants.
