Acclimatization is a significant stage in the mass multiplication of any vegetable species through in vitro culture, so that knowing the most influencing factors on vitroplant survival is important when arranging a handling strategy for optimizing a protocol. Therefore, this research work was carried out at the Department of Plant Genetics and Breeding from the National Institute of Agricultural Sciences, aimed to know the influence of different substrates on vitroplant acclimatization of anthurium, a sort of ornamentals mainly appreciated by the diverse colors of its flowers. A randomized complete experimental design was used, besides applying the comparison analysis of proportions for the variable of vitroplant survival and variance analysis for the growth variables evaluated. Results showed differences among substrates, standing out the one made up by acid peat + cow manure + soil (3/5.5/1) as for survival and ball composition for transplanting to nursery. There were not significant differences for growth variables, maybe due to the slow phase development of the species tested, which indicates that it is not good to evaluate this variable for determining the protocol efficiency of in vitro Anturium andreanum micropropagation.
