Background and aims: Sorghastrum pellitum is a potentially ornamental grass species native to South America. Due to the demand for new native species by the floriculture market it is important to know if plants of this taxon can thrive under cultivation conditions and if they present variability for vegetative and/or reproductive attributes that make possible the selection of genotypes for their possible market entry. The objective of this work was to characterize genotypes derived from two populations of S. pellitum that grow in mountainous areas of the southeastern Tandilia Hills (Buenos Aires Province, Argentina).
M&M: Six genotypes of each population were used to obtain clones that were transferred to pots and grown outdoors in Balcarce, (Buenos Aires Province, Argentina), under a RCBD (n=3). Variables related to transplant survival, morphology and phenology were recorded in two successive growing seasons.
Results: Intra- and inter-population variability was detected for transplant survival, morphological characters, duration of phenological stages and flowering time.
Conclusions: The implantation capacity under cultivation conditions and the morphological and phenological variability detected in this work suggest that this species could be included in breeding programs to obtain cultivars for subsequent use in landscaping. On the other hand, differences found between what was recorded in this work and what is found in the descriptions of the reference literature highlight the need to analyze a large number of specimens from different areas of its distribution when making taxonomic descriptions of this species, and to consider the existence of interspecific hybrids. |

Introducción y objetivos: Sorghastrum pellitum es una Gramínea nativa de Sudamérica de gran potencial ornamental. Debido a la demanda de nuevas especies nativas por el mercado floricultor, resulta importante conocer si las plantas de esta especie prosperan en condiciones de cultivo y si presentan variabilidad para los atributos vegetativos y/o reproductivos, que posibiliten la selección de genotipos para su eventual incorporación en el mercado. El objetivo de este trabajo fue caracterizar genotipos de dos poblaciones de S. pellitum provenientes de áreas serranas del sudeste del Sistema Serrano de Tandilia (Buenos Aires, Argentina). M&M: Se utilizaron seis genotipos de cada población a partir de los cuales se obtuvieron clones que se dispusieron en macetas al aire libre en Balcarce (Buenos Aires, Argentina), siguiendo un DBCA (n=3). En dos estaciones de crecimiento sucesivas se evaluaron variables relacionadas a la supervivencia al trasplante, a la morfología y a la fenología. Resultados: Se registró variabilidad intra- e inter-poblacional en la supervivencia al trasplante, así como en caracteres morfológicos, duración de las etapas fenológicas y épocas de floración. Conclusiones: La capacidad de implantación bajo cultivo y la variabilidad detectada, sugieren que esta especie podría ser incluida en programas de mejoramiento genético, para la obtención de cultivares y posterior uso en planteos paisajísticos. Por otra parte, las diferencias encontradas entre lo registrado en este trabajo y la bibliografía, ponen en evidencia que para realizar descripciones taxonómicas de S. pellitum es necesario analizar un gran número de ejemplares, provenientes de las distintas áreas de su distribución, así como considerar la existencia de híbridos interespecíficos.
