The growth of the tropical flower market has demanded a consistent search for new varieties, primarily those endowed with an exotic profile, but that are also beautiful and durable. The genus Heliconia, naturally found in the Amazon region, is among the most prominent of tropical flowers. Looking to augment the genetic variability available in Heliconia chartacea var. Sexy Pink, biotechnological research was conducted with the application of colchicine to induce polyploidy in plants from this species. With that in mind, this study was undertaken to evaluate the establishment of plants in the field drawn from in vitro polyploidy induction assay and to determine the morphological and physiological characteristics of 38 H. chartacea var. Sexy Pink clones. The characterization analyzes were performed through 49 morphological descriptors and a stomatal density evaluation using microscopy. The genotype 35 exhibited the greatest morphological variations, with alterations in the position and coloring of the inflorescence, in addition to having the edges of the entire limbus. Genotype 18 featured the lowest amounts for plant height and inflorescence size, showing promise for research geared towards use in reduced environments. Some genotypes did not have any flowering and are recommended exclusively for landscape composition such as foliage, since their exotic characteristics allow for this. The genotypes that were evaluated displayed stomata with tetracytic morphology and guard cells that had no significant changes. However, genotypes with greater equatorial diameter and stomatal density were obtained in relation to the mother-plant. Overall, the induction of polyploidy allowed for clones to be obtained with a high variability for the characteristics of the leaf, pseudostem and inflorescence, with various attributes that confer a more efficient post-harvest management to some genotypes, in addition to favorable aspects for commercialized purposes as a cut flower.
