Propagation of in vitro plants through other culture media rather than the traditional ones has been widely researched, with satisfactory results. However, to increase the effectiveness of these media, the addition of organic products has been presented satisfactory results. Therefore, the objective of this work was to evaluate the influence of the FishFértil® organic fertilizer on the in vitro cultivation of the Brazilian orchid Cattleya labiata. Treatments included FishFértil® fertilizer

At 180 days, shoot height, number of leaves, leaf area, number of roots, root average length, shoot and root dry mass and the shoot: root ratio were evaluated. The experimental design was entirely randomized, with 10 replications, each one containing 10 plantules. Data were submitted to an analysis of variance and regression analysis, at 5% of significance. The FishFértil® organic fertilizer at the concentration of 6 mL L-1 promoted better plantule growth of Cattleya labiata, subcultivated in vitro, in a simplified culture medium.
