Abstract:
A study of vegetative propagation has been carried out using cuttings of three elm species: Ulmus minor Mill, Ulmus laevis Pall. and Ulmus pumila L. The objective of the study was to determine their survival rate and growth under different concentrations of IBA (indole-3-butyric acid) solutions. The hormonal treatments consisting of 0, 2,000, 3,000 and 4,000 ppm IBA with 0.75% humectant and 15% NaOH, were distributed using a randomized design with three replicates for each treatment. The evaluated variables were survival rate, diameters and height after almost a year and a half from the planting. This work gives a general overview of which could be the best IBA treatment for propagate these species. The results obtained from the screening, allow a greater knowledge of these species and will help to make future decisions about their propagation for possible uses as biomass producers. Results of this work showed that survival percentages and growth is dependent of both: taxon and IBA concentration. Highest success percentage was achieved with clone 16 of Ulmus pumila L., while Ulmus laevis Pall. was the taxon that showed the worst survival percentage for all treatments.
