Resumo: | The present research aimed to evaluate the foliar morphology (morphometry and leaf venation) of origins of maté collected in southern Brazil and Argentina. For the study of the morphometry, thirty leaves/plant were analyzed, and five measurements (leaf total length, maximum width, length from the base until maximum width, area and petiole length) and two indices were obtained (total leaf length on maximum width and length from basis until maximum width on total leaf length). The leaves were clarified by the clarification technique and examined in stereomicroscope. The highest and lowest values of leaf morphometry were, respectively, 118 and 67 mm for total leaf length, 51 and 34 mm for maximum width, 78 and 42 mm for length from the base until the maximum width, 16 and 10 mm for petiole length, 2.3 and 2 mm for total length on maximum width, and 0.65 and 0.6 for length from the base until the maximum width on total leaf length. In regards to leaf venation, differences between leaves of different origins were not observed, which presented pinnate primary venation; semicraspedodromous secondary venation, alternate percurrent and sinuous tertiary venation, regular polygonal reticulate quaternary venation and dichotomizing 5tha vein category |

Analisaram-se 30 folhas de cada procedência, obtendo-se cinco medidas (comprimento total da folha, largura máxima, comprimento desde a base até a largura máxima, comprimento do pecíolo e área) e calculando-se dois índices (comprimento total sobre a largura máxima e comprimento desde a base até a largura máxima sobre o comprimento total da folha). Para a nervação foliar, as folhas foram clarificadas por meio da técnica de diafanização. Os maiores e menores valores morfométricos foram, respectivamente, 118 e 67 mm para comprimento da folha, 51 e 34 mm para largura máxima, 78 e 42 mm para comprimento desde a base até a largura máxima, 16 e 10 mm para comprimento do pecíolo, 2,3 e 2 mm para comprimento sobre largura máxima e 0,65 e 0,6 para comprimento desde a base até a largura máxima sobre o comprimento da folha. Quanto à nervação foliar, não foram observadas diferenças entre as folhas das distintas procedências, as quais apresentaram nervação primária penada, nervação secundária semicraspedódroma, nervuras terciárias com percurso alternado e sinuoso, nervação quaternária reticulada, constituída por polígonos regulares e nervação de 5ª ordem dicotomizanteUniversidade Estadual De Maringá2009-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordapplication/octet-streamhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/344810.4025/actascibiolsci.v31i4.3448Acta Scientiarum.
