Comparative study of the bio-mineral composition of four species of the genus Gunnera in Argentina. This study aimed to characterize and analyze comparatively, the biominerals of species of the genus Gunnera from Argentina (G. apiculata, G. lobata, G. magellanica and G. tinctoria). It is described a...

Comparative study of the bio-mineral composition of four species of the genus Gunnera in Argentina. This study aimed to characterize and analyze comparatively, the biominerals of species of the genus Gunnera from Argentina (G. apiculata, G. lobata, G. magellanica and G. tinctoria). It is described and analyzed both qualitatively and quantitatively calcium biominerals as siliceous, located in the leaf tissues. We identified taxonomic validity anatomical elements that distinguish the taxa to species or group of species, such as the shape of the ends axis, the size and number the dominant calcium and silica phytoliths morphotypes. The results obtained in the study of biomineralizations may relate to the characteristics of the habitat where plants grow and may be useful as tools for environmental assessment and/or past vegetation in these regions. Este trabajo tuvo por objeto caracterizar y analizar, comparativamente, la producción de biominerales en especies del género Gunnera presentes en Argentina (G. apiculata, G. lobata, G. magellanica y G. tinctoria). Se describe y analiza cualitativa y cuantitativamente los biominerales tanto cálcicos como silíceos, ubicados en sus tejidos. Se ha identificado elementos anatómicos foliares con validez taxonómica que permiten diferenciar los taxa a nivel de especie o grupo de especies, como ser, la forma de los extremos de los ejes, tamaño y número de los calciofitolitos; morfotipos silíceos predominantes. Los resultados obtenidos en el estudio de las biomineralizaciones pueden relacionarse con las características del hábitat donde crecen estas plantas, pudiendo ser útiles como herramientas para el estudio ambiental y/o de vegetaciones pasadas de esas regiones.
