Abstract: O conhecimento da anatomia da folha é crucial para o entendimento da adaptação das plantas ao ambiente. O objetivo deste estudo foi descrever a anatomia da lâmina foliar de 11 espécies lenhosas, frequentes nas savanas do extremo norte da Amazônia, com ênfase na identificação de atributos adaptativos a ecossistemas abertos, sujeitos a forte insolação e déficit hídrico sazonal. Amostras de folhas foram coletadas e processadas segundo técnicas usuais para estudos de anatomia e histoquímica. Bowdichia virgilioides… Show more

“…The organization of the dorsiventral mesophyll of B. sericea is similar to that of B. basiloba (Araújo et al, 2010), but differs from the type described for B. coccolobifolia B. crassifolia, B. lancifolia, and B. verbascifolia by Araújo et al (2010) and Ferreira et al (2015).…”

“…Some anatomical characters observed under LM, such as epidermal cell shape, numbers of layers of epidermal cells, and the stomatal classification presented in this work corroborate the observations of Malpighiaceae made by Metcalfe and Chalk (). The epidermal cells are thin, with anticlinal walls straight to curved, as described by Ferreira et al () for B . coccolobifolia , B .…”

“…These lower SLA values are the result of the increased investment in the epidermis and mesophyll thickness, leading to the construction of leaves with elevated thickness (Vile et al 2005) compared with plants under shade. The literature reports that elevated tissue thicknesses are related to adaptations to water economy and protection against high irradiances (Fahn & Cutler 1992;Voguelmann 1993), situations that are commonly reported for Brazilian savannas (Bieras & Sajo 2009;Ferreira et al 2015). Leaves with lower SLA values are also capable of performing higher photosynthetic rates in a leaf area basis, a situation found in many non-arboreal plants in savannas of Central Brazil subjected to natural Table 3.…”

“…É visto que essas estruturas podem atuar na proteção do tecido foliar contra herbivoria, regulação de cálcio, desintoxicação, equilíbrio iônico, suporte e rigidez de tecido. As drusas presentes no parênquima esponjoso podem atuar na reflexão uniforme da luz solar entre as células do mesofilo, o que pode explicar no presente trabalho as folhas de sombra apresentarem maior quantidade de drusas (LARCHER, 2001;FRANCESCHI;NAKATA, 2005;FERREIRA et al, 2015).…”
