The flower anatomy of five species of Myrteae and its contribution to the taxonomy of Myrtaceae
Provedor de dados: Acta Botanica Brasilica
Autores: Martos,Luana; Galan,Adrielle Tayrine Oliveira Froemming; Souza,Luiz Antonio de; Mourão,Káthia Socorro Mathias.
ABSTRACT Considerable effort has been spent towards understanding the phylogeny of Myrteae, and based on the phylogenetic data presently available the traditional subdivision of Myrteae into three subtribes is not supported. The present paper aims to assess the usefulness of floral characters in distinguishing five species that represent five of the six South American clades of Myrteae (Myrtaceae). Floral buds and flowers of Campomanesia adamantium, Eugenia pitanga, Myrceugenia alpigena, Myrcia multiflora and Myrciaria cuspidata were collected from individual plants growing in the Cerrado (Brazilian/Central South American savanna). Among these species, the perianth of E. pitanga is the most distinct due to its vasculurization and pilosity. The hypanthium...

Pericarp ontogenesis with emphasis on the dispersal apparatus of three weed species of Faboideae (Fabaceae)
Provedor de dados: Acta Botanica Brasilica
Autores: Trzeciak-Limeira,Flavia; Pinto,Daniela Dias; Mourão,Káthia Socorro Mathias.
It is known that the efficient dispersal is one among other features that amplify the invasion potential of a plant. Knowledge of the ontogeny, morphology and fruit dispersal of species is indispensable for weed control in crops. To identify the pericarp structures involved in the fragmentation and dehiscence processes and other features related to dispersal, we studied the pericarp development of Aeschynomene evenia Wright, Desmodium incanum (Sw.) DC. and Vigna luteola (Jacq.) Benth. (Fabaceae-Faboideae), all of which are considered weeds in certain situations. For light and scanning electron microscopy studies, we fixed and processed buds, flowers and fruits, according to usual methods, at different stages of development. We observed that the...

Fruit ontogenesis in Clusia parviflora Humb. &amp;amp; Bonpl. ex Willd. (Clusiaceae)
Provedor de dados: Acta Botanica Brasilica
Autores: Mourão,Káthia Socorro Mathias; Marzinek,Juliana.
Aspects of the morpho-anatomy of developing fruits and seeds of Clusia parviflora are presented and discussed as a continuation of the study of these organs in Clusiaceae. The fruit is a septifrage capsule; the suberized exocarp is derived from the external epidermis of the ovary. The mesocarp originates from the ovarian mesophyll and remains parenchymal in nature. The endocarp is derived from the internal epidermis of the ovary and the endocarp is derived from the inner ovary epidermis as well as from three to four adjacent subepidermal layers, with tangentially elongated cells which become lignified and contribute to fruit dehiscence. The ovules are anatropous, bitegmic, with an endothelium, and give rise to equally anatropous seeds. The exotesta has...

Morfoanatomia dos órgãos vegetativos de Piper crassinervium H.B. &amp;amp; K. (Piperaceae)
Provedor de dados: Acta Botanica Brasilica
Autores: Albiero,Adriana Lenita Meyer; Paoli,Adelita Aparecida Sartori; Souza,Luiz Antonio de; Mourão,Káthia Socorro Mathias.
Objetivando auxiliar trabalhos taxonômicos e farmacobotânicos, foram realizados estudos morfoanatômicos dos órgãos vegetativos de Piper crassinervium H.B. &amp;amp; K. (jaborandi). O material foi analisado seguindo-se técnicas usuais de corte e coloração. P. crassinervium é um arbusto de caule ereto, de folhas estipuladas e alternas. Dentre as características anatômicas importantes para a sua identificação destacam-se: parênquima cortical radical com esclereídes; córtex caulinar com faixas descontínuas de colênquima e tecido vascular organizado em dois círculos descontínuos de feixes colaterais, delimitados por endoderme com estrias de Caspary; folha dorsiventral, hipoestomática, com estômatos ciclocíticos e tetracíticos e hipoderme unisseriada, porém, com...

Fruit ontogeny of Garcinia gardneriana (Planch. &amp;amp; Triana) Zappi (Clusiaceae)
Provedor de dados: Acta Botanica Brasilica
Autores: Asinelli,Marta Eglaé Camargo; Souza,Maria Conceição de; Mourão,Káthia Socorro Mathias.
Garcinia gardneriana (Clusiaceae) is a small to medium-sized tree that usually occurs on the floodplains of the Paraná River and it is an important food source for the local inhabitants. The fruit itself is consumed in natura, and juices and sweets are made from it. The purpose of this study was to describe morphological and structural aspects of fruits and seeds of this species in order to classify the fruit type and the pulpy layer which involves the seeds. The material analyzed consisted of ovary and fruits in different stages of development, collected from five plants from Aurélio Island, Baía River (MS, BR) and the description was done according to standard procedures in anatomy. The fruit is a yellowish-orange spherical berry ("bacóide" type). The...

Vegetative propagation in Piperaceae species
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Souza,Luiz Antonio de; Moscheta,Ismar Sebastião; Mourão,Káthia Socorro Mathias; Albiero,Adriana Lenita Meyer; Iwazaki,Maísa de Carvalho; Oliveira,Jonathas Henrique Georg de; Rosa,Sônia Maciel da.
Piperaceae species of forest remnants of Maringá, Paraná, Brazil present vegetative propagation through root or stem (stolon). This reproduction type was verified in Piper amalago L., P. arboreum Aublet, P. xylosteoides (Kunth) Steud., Peperomia parnassifolia Miq. and Ottonia martiana Miq. Root and stem branches of these species were analyzed anatomically. Results indicated that the vegetative propagation in Piperaceae should be studied in other forests. New and additional studies should be made if the structural variations were induced environmentally or fixed genetically.
