1. Desenvolvimento in vitro e imunolocalização de 5-metilcitosina em raízes tuberizadas e não-tuberizadas de Viguiera arenaria Baker (Asteraceae) / In vitro development and immunolocalization of 5-methylcytosine in tuberized and nontuberized roots of Viguiera arenaria Baker (Asteraceae)
Viguiera arenaria Baker is an herbaceous Asteraceae from Cerrado presenting alternate phyllotaxis, capitulum inflorescence and tuberized roots. Although phytochemical analyses have found substances with biological activities of therapeutic interest, little is known about the biology of the plant. In this study, we sought to contribute to the knowledge of asp

2. IN VITRO AND EX VITRO PROPAGATION OF LOURO-PARDO (Cordia trichotoma (Vell.) Arrabida ex Steudel) / PROPAGAÇÃO IN VITRO E EX VITRO DE LOURO-PARDO (Cordia trichotoma (Vell.) Arrabida ex Steudel)
Although the louro-pardo (Cordia trichotoma Vell.) is native forest specie with high timber potential, there are still scarce studies that approach the production of seedlings of this species by vegetative propagation. The objective of this work was to evaluate the vegetative propagation of the louro-pardo by the techniques of cuttings and micropropagation.

3. Micropropagação e anatomia foliar de Canela-de-Ema (Vellozia flavicans Mart. ex Schult f.-Velloziaceae) em diferentes condições ambientais
Canela-de-ema (Vellozia flavicans Mart. ex Schult. f.) is a shrub native of Brazilian Cerrado and presents great potential ornamental. Limitations in the conventional cultivation and the slow growth of the plant justify the use of techniques of tissue culture to propagate the species. The objective of this study was to establish a protocol for micropropagati

4. Morphogenesis in vitro, phytochemical analysis and anatomical characterization of neem (Azadirachta indica A. Juss) / Morfogênese in vitro, análise fitoquímica e caracterização anatômica de nim (Azadirachta indica A. Juss)
The Azadirachta indica A. Juss species, popularly known as neem, belongs to the Meliaceae family, which has great potential for azadirachtin (AZA) production; however, neem has recalcitrant seeds, cross-pollination and variable content of AZA. Four experiments were conducted in order to understand the in vitro growth limiting factors of these plants and chan

5. Phytotoxic and antifungal compunds from legume seeds that accumulate glactomannan and xyloglucan as cell wall storage polysacharides / Substancias fitotoxicas e antifungicas em sementes de leguminosas que acumulam gelactomanano e xiloglucano como carboidratos de reservas de parede celular
Sesbania virgata (Cav.) Pers. and Hymenaea courbaril L. var. stilbocarpa (Fabaceae) are two tropical legume species with seeds that contain galactomannan and xyloglucan, respectively, as seed storage polysaccharides, which are broken down after germination, generating large amounts of monosaccharides and oligosaccharides. Part of these sugars is released to

6. IN VITRO GERMINATION OF Pinus taeda L. FROM SELECTED SEEDS / GERMINAÇÃO IN VITRO DE Pinus taeda L. A PARTIR DE SEMENTES SELECIONADAS
Pinus taeda L. is among the more planted forest species in Brazil due its desirable characteristics of production and industrial quality. Currently, it has been necessary to be developed techniques that make possible the massal production of improved genotypes and the tissue culture techniques offer this possibility. Gotten plants in vitro from seeds possess

7. Physical-chemical characterization and micropropagation of the passion fruit (Passiflora setacea DC.) / CaracterizaÃÃo fÃsico-quÃmica do fruto e micropropagaÃÃo do maracujÃ-do-sono (Passiflora setacea DC.)
In function of the propagation difficulty of the Passiflora setacea DC., in seed germination, as well as in the rooting of cuttings, tissue culture techniques become viable for its propagation. The object was to obtain in vitro germination and to determine the culture medium for the in vitro micropropagation of Passiflora setacea DC. The experiments were car

8. Germination and morphogenesis in vitro of mahogany (Swietenia macrophylla King) / Germinação e morfogênese in vitro de mogno (Swietenia macrophylla King)
The objective of this work was to develop techniques of in vitro regeneration of mahogany (Swietenia macrophylla), through epicotyls segments, inverted epicotyls and leaf explants from mahogany plantlets germinated in culture medium. Also the best concentration and time for seeds sterilization and the sterilizing agent were determined, as well as the best so
