13. Revisiting hydropotes of Nymphaeaceae: ultrastructural features associated with glandular functions
ABSTRACT Hydropotes are specialized epidermal structures involved in water and mineral flux into and out of the plant body. We analyzed hydropote morphology of four species of Nymphaeaceae: Nymphaea caerulea, Nymphaea lotus, Nymphaea rubra, and Victoria amazonica. Leaf samples were processed following conventional techniques for plant anatomy and for scannin

14. Anatomical and histochemical characterization of Dipteryx odorata and Taralea oppositifolia, two native Amazonian species
Abstract Dipteryx odorata (Aubl.) Willd. and Taralea oppositifolia Aubl., Fabaceae: Dipterygeae, are two Amazonian species of great economic and pharmacological potential. The anatomy of these species, however, remains poorly studied. The aim of this work was to inventory leaf anatomical characteristics of D. odorata and T. oppositifolia and to locate and id

17. Permineralized conifer-like leaves from the Jurassic of Patagonia (Argentina) and its paleoenvironmental implications
Abstract Abstract: Anatomically preserved conifer-like leaves from the Middle Jurassic La Matilde Formation at the Barda Blanca locality in the Gran Bajo de San Julián area, southern Patagonia are described here. Leaves are assigned to conifers based on the following foliar features: thick-walled epidermal cells, a sclerenchymatic hypodermis, resin canals a

18. Forage potential of Urochloa genotypes by using leaf anatomy
RESUMO: O potencial de digestibilidade das folhas de forrageiras depende da quantidade de seus tecidos com baixa deposição de lignina nas paredes celulares, principalmente o parênquima e floema. O presente trabalho objetivou avaliar a estrutura foliar de diferentes genótipos de Urochloa e seu potencial de digestibilidade foliar. Foram avaliadas as culti

19. Comparative anatomy and histochemistry of the leaf blade of two species of Artocarpus
Abstract Abstract: In Brazil, there are two species of Artocarpus that were introduced: Artocarpus altilis (Parkinson) Fosberg, known as fruta-pão, and Artocarpus heterophyllus Lam., known as jaca. Both are used as food and medicine. The objective of this work was to conduct a comparative anatomical and histochemical study between A. altilis and A. heteroph

20. Schinus molle: anatomy of leaves and stems, chemical composition and insecticidal activities of volatile oil against bed bug (Cimex lectularius)
Abstract The present work investigates the leaf and stem anatomy, chemical composition and insecticidal activities (against Cimex lectularius Linnaeus, 1758) of the volatile oils of Schinus molle L., Anacardiaceae, a Brazilian native traditional medicinal plant. Noteworthy micro-morphological features that can help in the identification and quality control o

21. Anatomical modifications of Butia capitata propagated under colored shade nets
Abstract The jelly palm plant [Butia capitata (Martius) Beccari] is a native palm of the Cerrado biome used for many purposes in northern Minas Gerais State, Brazil. Dormancy is common in palm seeds, resulting in slow and uneven germination that may take years to complete. Modification in the growth pattern, anatomical parameters, physiological and biochemic

23. Colored shade nets induced changes in growth, anatomy and essential oil of Pogostemon cablin
ABSTRACT The purpose of this investigation was to determine the influence of colored shade nets on the growth, anatomy and essential oil content, yield and chemical composition of Pogostemon cablin. The plants were cultivated under full sunlight, black, blue and red nets. The harvesting was performed 5 months after planting and it was followed by the analysi

24. Anatomy and volatile oil chemistry of Eucalyptus saligna cultivated in South Brazil
ABSTRACT Eucalyptus saligna Sm., Myrtaceae, commonly known as Sydney blue gum, is often confused with several other species in the genus. The leaf volatile oils of the species have been reported to have antimicrobial, insecticidal, nematicidal, repellent and cytotoxicity properties. The present work provides anatomy as well as volatile oil chemistry of the s
