Fig. 4From: Combined inoculation with dark septate endophytes and arbuscular mycorrhizal fungi: synergistic or competitive growth effects on maize?Effects of fungal inoculation on IAA, GA, CTK and ABA levels in maize roots and shoots. CK, controls with sterilized DSE and/or AMF; AM, sterilized DSE with AMF; LD, low concentration of DSE with sterilized AMF; MD, medium concentration of DSE with sterilized AMF; HD, high concentration of DSE with sterilized AMF. AM + LD → AM + HD, different concentrations of DSE and AMF. Different letters above the columns indicate significant differences at P < 0.05Back to article page
