Leaf anatomy of predominant species in forests and grasslands of the Iberá

The Iberá macrosystem has several types of vegetation, where in addition to aquatic and marsh vegetation are found hydrophilic forests, savannahs with a predominance of grasses and grasslands with shrub species interspersed among the herbaceous species. Previous studies of leaf anatomy were only car...

Crystals epidermis stomata histology leaf mesophyll trichomes Cristales epidermis estomas histología hoja mesofilo tricomas The Iberá macrosystem has several types of vegetation, where in addition to aquatic and marsh vegetation are found hydrophilic forests, savannahs with a predominance of grasses and grasslands with shrub species interspersed among the herbaceous species. Previous studies of leaf anatomy were only carried out on aquatic and marsh plants. In this work, leaf anatomy was studied in predominant or frequent species growing in grasslands and forests of the Iberá macrosystem, with the aim of detecting leaf structural characters that may represent adaptive value to these environments. Leaves of 42 species corresponding to 26 families were analyzed with optical and scanning electron microscopy. Statistical analysis was performed based on a data matrix of the anatomical characters analyzed, also including the environment types in which the species studied grow. The analyzed characters of the epidermis were: cuticle design, stomata, trichomes, design of epidermal cells of both epidermis, where a predominance of identical morphology on both sides was observed. In the mesophyll, the type, presence and form of calcium and inulin crystals, and distribution of glandular structures such as laticifers, cavities and secretory cells were evaluated. The data reported are discussed in relation to the available literature. No constant characters associated with a particular vegetation type are found. Species living in the same environment do not have similar anatomical features, as shown by clustering analysis (UPGMA). El macrosistema Iberá presenta diversos tipos de vegetación, donde además de las acuáticas y palustres hay bosques hidrófilos, sabanas con predominio de gramíneas y praderas con especies arbustivas intercaladas entre las herbáceas. Estudios previos de anatomía foliar solo fueron realizados en plantas acuáticas y palustres. En este trabajo se estudió la anatomía foliar en especies predominantes o frecuentes que crecen en pastizales y bosques del macrosistema Iberá, con el objetivo de detectar caracteres estructurales de las hojas que puedan representar valor adaptativo a estos ambientes. Se analizaron hojas de 42 especies correspondientes a 26 familias, con microscopía óptica y electrónica de barrido. Se realizó un análisis estadístico en base a una matriz de datos, compuesta por los caracteres anatómicos y el ambiente en que crecen las especies estudiadas. Los caracteres analizados de la epidermis fueron: diseño de la cutícula, estomas, tricomas, diseño de células epidérmicas de ambas epidermis, donde se observa un predominio de idéntica morfología en ambas caras. En el mesofilo se evaluó su tipo, presencia y forma de cristales de calcio e inulina, y distribución de estructuras glandulares como laticíferos, cavidades y células secretoras. Los datos reportados son discutidos en relación a la bibliografía disponible. El análisis de agrupamiento (UPGMA) muestra que las especies que habitan en los mismos ambientes no presentan características anatómicas similares.
