Análisis morfológico, palinológico y sistemático de las Isoetales del Cono Sur de América del Sur

Macluf, Carmen Cecilia 26 April 2012 (has links)
La familia Isoetaceae tiene un único genero Isoetes L., que junto con Selaginella P. Beauv. (Selaginellaceae) constituyen el grupo de las Lycophyta heterosporadas. Isoetes L. es un género ampliamente distribuido con cerca de 200 especies, de las cuales alrededor de 50 crecen en América y aproximadamente 35 tienen distribución al sur de los Estados Unidos. Estas plantas muestran muy poca variabilidad morfológica, lo que dificulta la identificación de las especies, por lo que en general, las clasificaciones están basadas en caracteres palinológicos, con especial referencia a las características de las megasporas. El objetivo de esta investigación es el estudio de las especies de Isoetes L. que crecen en el Cono Sur de América meridional, actualizar su diversidad, definir el área de distribución de las mismas, efectuar el análisis de la morfología general de las plantas, y en particular de sus megasporas y microsporas. El estudio se llevó a cabo a través de observaciones con binocular estereoscópico, microscopios óptico y electrónicos de barrido y transmisión. / The family Isoetaceae is composed of only one genus Isoetes L., that together with Selaginella P. Beauv. (Selaginellaceae) constitute the group of the Lycophyta heterosporate. Isoetes L. is a genus widely distributed with circa 200 species, from which around 50 grow in America and approximately 35 are distributed in Southern North America. The aim of this study is the study of the Isoetes L. species that grow in the Southern South America, to up date their diversity, to define their area of distribution, to make a detailed analysis of their plant general morphology and in particular their megaspores and microspores. The study was performed with binocular stereoscope, light microscope and electron microscopes, scanning and transmission.
