| ABSTRACT: Popcorn (Zea mays var. everta) has a higher commercial value than common maize, in addition to being a popular food among consumers. Today, there is a constant search for cultivars with superior performance for several traits of interest in the case of popcorn, yield and popping expansion. On this basis, this project proposes to characterize progenies of popcorn with different values of expansion capacity regarding chemical composition and micromorphology. Kernels from the fifth cycle (C5) of intrapopulation recurrent selection were evaluated. The progenies were selected based on the popping expansion volume of their kernels. The kernels were quantified for amylose and analyzed for starch granule arrangement and pericarp thickness by scanning... |

| In commercial coffee species (Coffea arabica and Coffea canephora), fruit development is a lengthy process, characterized by tissue changes and evolutions. For example, soon after fecundation and up to mid development, the fruit is mainly constituted of the pericarp and perisperm tissue. Thereafter, the perisperm gradually disappears and is progressively replaced by the endosperm (true seed). Initially present in a "liquid" state, the endosperm hardens as it ripens during the maturation phase, as a result of accumulation of storage proteins, sucrose and complex polysaccharides representing the main reserves of the seed. The last step of maturation is characterized by the dehydration of the endosperm and the color change of the pericarp. Important... |

| Astronium graveolens é um representante arbóreo da família Anacardiaceae que se distribui desde o México até o centro-sul da América do Sul. O fruto é uma pseudo-sâmara com exocarpo unisseriado, suberificado e aderido ao mesocarpo. O mesocarpo é parenquimático, com grandes canais secretores associados aos feixes vasculares e localizados próximos ao endocarpo. O endocarpo parenquimático é bisseriado, sendo a camada que reveste o lóculo ligeiramente alongada radialmente. O óvulo é anátropo, unitegumentado, crassinucelado, com rafe dorsal evidente e hipóstase tanífera; apresenta obturador placentário e está inserido em posição apical-lateral no fruto. A testa, fortemente adnata ao pericarpo, apresenta as células da epiderme interna pequenas e de conteúdo... |

| The mature fruits of 10 South American species of Solanum sect. Torva were studied. Cross and longitudinal microtome sections, stained with astra blue/basic fuchsin, were made for microscopic examination. All species present an epidermis formed by a unistrate layer of small, isodiametric cells, with dense content and cellulosic walls. Immediately below, a hypodermis is always found, consisting of a well-defined layer of lignified cells with a single calcium oxalate crystal occupying the whole lumen of each cell. This is followed by one layer of cellulosic, isodiametric cells with dense cytoplasm and then several collenchymatous layers, sometimes with sclerified cell walls. The mesocarp comprises two zones histologically differentiated: an external one... |

| Fruits (pericarps and seeds) of the weedy species Sida rhombifolia L., S. urens L. and S. regnellii R. E. Fr. were analyzed structurally using light and scanning electron microscopy. The yellowish brown calyx is persistent on the mature fruit and consists of a crystalliferous hypodermis with U-shaped wall thickenings and homogeneous mesophyll. Fruits are schizocarpic, of the subtype coccarium, with a fibrous endocarp. Seeds are exotegmic and the embryos are clearly bent, with folded cotyledons. Structural features that are potentially significant to species' characterization are the structure of the ovary, the morphology of the mericarp apex, the pattern of the reticulate sclerenchymatous endocarp and the presence or absence of nonglandular trichomes in... |

| ABSTRACT Fruit morphology of the tribe Malveae has been discussed since the first taxonomic classifications of Malvaceae. The fruits are schizocarps, with some genera possessing an endoglossum. Besides morphological variation in the endoglossum, other differences include the number seeds per locule and ornamentation of the exocarp. An in-depth study of the fruit morphology of Malveae is essential to gain insight into the relationships among taxa of the tribe. Therefore, the present study aimed to describe the fruit morphology of Malveae, including micromorphology, variation in endoglossum structure and arrangement of seeds in the locule, to comprehensively evaluate the systematic relationships among its contained taxa. The results indicate morphological... |

| This study aims to give an overall view of fruit structure in Bromeliaceae, since these studies are extremely scarce in this family, showing the morphology, anatomy and ontogeny of fruits of six species belonging to six different genera, representing three subfamilies. All species studied have a tricarpellary and trilocular ovary, with an obturator covering the placental region. Dyckia maritima, Pitcairnia flammea, Tillandsia aeranthos and Vriesea carinata have capsular fruits (septicidal or biscidal), characterized mainly by the presence of macrosclereids in the exocarp or endocarp, fibers in the ventral region of the carpels, six dehiscence lines and three vascular bundles in each carpel. Aechmea calyculata and Billbergia nutans have fruits classified as... |

| The morphology and structure of the flowers and fruits of Chamissoa altissima (Jacq.) Kunth during the development were analyzed. The plant material was fixed in FAA 50, embedded in historesin and sectioned according to standard techniques. The flowers presented tepals with betalain and homogeneous mesophyll; receptacular nectary; anthers with epidermis, endothecium, one middle layer, and uninucleate tapetum; and monocarpelar ovary with homogeneous mesophyll. The fruit was a circumscissile capsule, presented the same number of cellular layers that the ovary, and possessed subendocarpic sclerenchyma. The seed was bitegmic, exotestal and perispermic. |

| (Morphology and anatomy of the developing fruit of Maclura tinctoria, Moraceae). Maclura tinctoria (L.) D. Don ex Steudel was selected for the present study due of its economic and medicinal importance. The purpose of this investigation is to present a detailed description of the fruit development, specially by: (a) defining the fruit type presented by the species, and (b) characterizing the seed type of the species based upon the presence or not of mechanical tissue on the seed-coat. The fruit originates from the subglobose female inflorescence which consists of small unipistillate flowers with superior ovary, unilocular and uniovular apical placentation. The mature fruit is multiple, constituted of small drupes. The ovule is ana-campylotropous,... |

| Euphorbiaceae s.l. presents several morphological types of fruits, of which the schizocarp is the most common. The fruits of weed species of Euphorbia graminea Jacq., Euphorbia heterophylla L., Euphorbia hirta L. (= Chamaesyce hirta (L.) Millsp.) and Euphorbia prostrata Aiton (= Chamaesyce prostrata (Aiton) Small) are objects of this study. Inflorescences and fruits in development were collected on the campus of the State University of Maringa (UEM), Brazil, fixed in FAA 50 and glutaraldehyde, dehydrated and sectioned with a rotary microtome according to standard morphology and anatomy techniques. The species present several anatomical similarities, though there are some differences related to the outer epidermis of the ovaries, which is glabrous in E.... |
