Effect of Different Strains of Arbuscular Mycorrhizal Fungi (AMF) on Macro and Micro Nutrient uptake in Micropropagated Chrysanthemum Plantlets

Effect of different Arbuscular Mycorrhizal Fungi (AMF) on uptake of macro and micronutrients by in vitro raised plantlets of chrysanthemum cv. Yellow Bangla has been studied. Four AMF strains namely, Acaulospora laevis, Acaulospora scorbiculata, Glomus fasciculatum and mixed AMF strains (Nutrilink®) were used to screen the suitable AMF strain for micropropagated 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 observed in uptake of Fe and Mn at 90 DAI in both shoot and root samples. However, maximum accumulation of Zn was observed in shoots of Glomus fasciculatum inoculated plantlets. The experiments revealed significant increase of nutrient uptake in both shoot and roots in the plantlets inoculated with mixed AMF strains (Nutrilink®) followed by Glomus fasciculatum inoculated microplants.
