'Cleópatra' mandarin submitted to mycorrhization and to a brassinosteroid analogue

'Cleópatra' mandarin submitted to mycorrhization and to a brassinosteroid analogue. The objective of this study was to evaluate the effects of different concentrations of a brassinosteroid analogue and inoculation of the vesicular-arbuscular mycorrhizal fungi (AMF) Acaulospora scrobiculata on the 'Cleópatra' mandarin from the sowing until transplant point. The experiment was conducted under greenhouse conditions at Universidade Estadual do Norte Fluminense. The experimental design utilized was a randomized block with a 5x2 factorial scheme with 4 replications, using 5 concentrations of a brassinosteroid analogue, Biobras-16 (0.0; 0.1; 0.5 and 1.00 mg L-1) and with or without AMF inoculation. The AMF inoculation caused increment in height, number of leaves, diameter of the stem, leaf area and dry mass of the leaf and stem. The Biobras16 promoted an increment of the diameter of the stem. The P, K, Fe and Mn contents were higher in the AMF inoculated plants. Results show that the association of the two factors studied modifies the growth of rootstock.
