3. Morpho-anatomy of the inflorescence of Musa × paradisiaca
ABSTRACT Bananas and plantains are herbaceous monocotyledonous plants belonging to the genus Musa, Musaceae, which has a widespread distribution around the world. Various parts of banana plant are commonly used in traditional medicines. Several species of Musa are reported to possess anti-inflammatory, anti-hyperglycemic and antidiabetic properties. This wor

4. Differential Tolerance of Clones of Eucalyptus grandis Exposed to Drift of the Herbicides Carfentrazone-Ethyl and Glyphosate
RESUMO: A deriva dos herbicidas carfentrazone-ethyl e glyphosate pode afetar o crescimento inicial do eucalipto. Este trabalho objetivou avaliar o efeito da deriva de carfentrazone-ethyl e glyphosate sobre a fotossíntese, a morfoanatomia foliar e o crescimento inicial de dois clones de Eucalyptus grandis. Foram realizados dois ensaios em esquema fatorial 2

5. Phytotoxic Potential of the Crude Extract and Leaf Fractions of Machaerium hirtum on the Initial Growth of Euphorbia heterophylla And Ipomoea grandifolia
RESUMO: Alelopatia é o termo utilizado para definir qualquer processo envolvendo metabólitos secundários produzidos por plantas e microrganimos que influenciem no crescimento e desenvolvimento de sistemas agrobiológicos. Na atualidade, busca-se encontrar aleloquímicos de interesse e saber como aplicá-los em bio-herbicidas para combater plantas daninhas

6. Changes in phenotypic variability of two tropical woody species due to short and long-term exposure to different irradiances
ABSTRACT Studies addressing the physiological and anatomical responses of plants under different light intensities normally are performed in short term. Thus, the present study includes a long term analysis. This study aims to verify whether the phenotypic variability off attributes in two woody tropical specieis, Paquira aquatica and Sterculia foetida, are

7. Somatic embryogenesis in Carica papaya as affected by auxins and explants, and morphoanatomical-related aspects
ABSTRACT The aim of this study was to evaluate somatic embryogenesis in juvenile explants of the THB papaya cultivar. Apical shoots and cotyledonary leaves were inoculated in an induction medium composed of different concentrations of 2,4-D (6, 9, 12, 15 and 18 µM) or 4-CPA (19, 22, 25, 28 and 31 µM). The embryogenic calluses were transferred to a maturati

8. Grouping of anthurium genotypes based on genetic and morpho-anatomical features
Abstract The study aimed at investigating the anatomic and DNA content characteristics of 12 Anthurium genotypes. A large genomic amplitude was observed in the genotypes, ranging from 4.95 to 22.74 pg of DNA. Differences in DNA content, assessed by flow cytometry, allowed the differentiation between the genotypes A. andraeanum, A. affine, A. bomplandii, and

9. Antiherbivory defense mechanisms along an environmental gradient in restinga
ABSTRACT Plant-herbivore interactions have directed the evolution of defense mechanisms in plants, which can vary intraspecifically according to environmental quality. This study evaluated variation in the production of antiherbivory defenses in plant species distributed along an environmental gradient of restinga. The study was performed in Parque Estadual

10. Morphoanatomy of nectaries of Chamaecrista (L.) Moench sections Chamaecrista , Caliciopsis and Xerocalyx (Leguminosae: Caesalpinioideae)
ABSTRACT Nectaries are specialized structures that secrete nectar. Several species of Chamaecrista possess nectaries on the petiole, which have been shown to vary widely in morphology and the chemical nature of their secretion. However, a comprehensive investigation of the nectaries of the clade formed by sect. Chamaecrista, Caliciopsis and Xerocalyx has yet

11. Morpho-anatomical study of Stevia rebaudiana roots grown in vitro and in vivo
ABSTRACT Stevia rebaudiana (Bertoni) Bertoni, Asteraceae, is used as a food additive because its leaves are a source of steviol glycosides. There are examples of tissue culture based on micropropagation and phytochemical production of S. rebaudiana leaves but there are few studies on adventitious root culture of S. rebaudiana. More than 90% of the plants use

12. Comparative morphoanatomical analysis of Mikania species
ABSTRACT Mikania belongs to the Asteraceae family and includes a wide range of promising pharmacological activities. Several species of Mikania, which is popularly known in Brazil as “guaco”, occur in Southern Brazil and their external morphology is similar. The aim of this study was to investigate the morpho-anatomical characteristics of the leaf and st
