Abstract Erythroxylum is common in the Brazilian Cerrado. Species from this genus have ecological, pharmacological and popular medical importance. Based on information, aims of study was to perform a descriptive quantitative morphoanatomical tortuosum leaves present two environments: cerrado sensu stricto campo rupestre. To carry out these studies, 24 fully developed were collected fixed individuals across both environments. For anatomy study, following measurements made: leaf area, length,...
Abstract Seasonally Dry Tropical Forests experience pronounced precipitation seasonality, intense solar radiation, and high temperatures, which often translate into levels of deciduousness during the dry season. In these environments, deciduous species coexist with some evergreen that are able to maintain their canopy leaves throughout To understand strategies behind this behavior, we analyzed leaf anatomical traits 13 individuals Sarcomphalus joazeiro both wet seasons in a seasonal forest....
The aim of the study was to evaluate effect different light conditions on internal structure Piper aduncum L. leaves. P.aduncum seedlings were grown for 4 months under achieved with shading nets (50, 70, and 100% luminosity) photoconversion in red (RN) blue (BN) colors. Two fully expanded leaves located at third node collected from five plants per treatment paradermal transverse sections. In sections, stomatal density, polar equatorial diameters, ratio between trichome density abaxial...
The genus Eremanthus (Asteraceae) covers mostly arboreal species, popularly known as “candeia”. Three of these E. erythropappus, incanus and glomerulatus, are endemic to extensively distributed in Brazil. “Candeias” commercial interest due the good quality their wood and, mainly, essential oils, used for various therapeutic purposes. These species “candeia” have similar vegetative characteristics, mainly erythropappus incanus, making them difficult differentiate field. This study aimed...
Para verificar a influência da altitude na estrutura anatômica de folhas e do xilema secundário galhos indivíduos espécie Clethra scabra Pers. (Clethraceae) ocorrentes Serra Mantiqueira, estado Minas Gerais, realizaram-se coletas amostras nas cotas altitudinais 1500, 1700, 1900 2100 m (metros). As coletados foram fixados preparados seguindo procedimentos usuais microtécnica vegetal. Procederam-se análises anatômicas quantitativas utilizando software análise imagem. C. são hipoestomáticas com...
