- Abstract
Cattleya warneri var. concolor (Orchidaceae) is an endangered epiphyte plant with ornamental economic potential. In this research, we have studied in vitro growth of C. warneri's seedlings at different doses of humic acids isolated from vermicompost. The evaluation on growth promoted by AH was performed using variables number of leaves and roots, fresh and dry weight of leaves and roots and estimates of the H+-ATPase enzyme activity. The results indicated that the humic material obtained was able to increase the growth of the studied plant and promoting stimuli associated with the said enzyme activity. It is thus established, an efficient biostimulant aimed at producing Cattleya warneri var. concolor seedlings.
