1. Micropropagation of Guadua chacoensis (Rojas) Londoño & P. M. Peterson1
RESUMO A cadeia produtiva de bambu, no Brasil, ainda é incipiente, e tem baixa oferta de mudas devido aos métodos convencionais de propagação. Objetivou-se, aqui, estabelecer um protocolo de micropropagação para Guadua chacoensis. Explantes de matrizes cultivadas em ambiente controlado resultaram em menor contaminação, relativamente aos de plantas cu

2. Mini-incubators improve the adventitious rooting performance of Corymbia and Eucalyptus microcuttings according to the environment in which they are conditioned
ABSTRACT We addressed a major challenge in the in vitro clonal propagation of Corymbia citriodora, Eucalyptus urophylla and E. benthamii by using an ex vitro adventitious rooting strategy in a mini-incubator. Mini-incubators were placed in four environments for rooting. A shade house with no fogging system and a greenhouse with no ventilation but with a fogg

3. Efficient and new method for Tectona grandis in vitro regeneration
Abstract The aim of this study was to develop a shoot regeneration protocol for Tectona grandis by examining the effects of pretreatments, regeneration culture medium, adventitious rooting, and acclimatization. The best organogenic potential was achieved when hypocotyls and cotyledonary segments from seedlings germinated on a medium containing TDZ, were cult

4. Micropropagation of Endangered and Decorative Species Dianthus pinifolius Sibth. et Sm.
The aim of this study was to establish an efficient protocol for the in vitro propagation of the endangered, endemic and decorative species Dianthus pinifolius Sibth. et Sm. The effects of different concentrations of 6-benzylaminopurine (BAP) and naphtalenacetic acid (NAA), and different explant types (single-node cuttings, terminal buds and shoot cuttings)

5. An efficient system for in vitro propagation of Bouchea fluminensis (Vell.) Mold. (Verbenaceae)
This study aimed to establish and propagate in vitro plants of Bouchea fluminensis, a medicinal species known in Brazil as gervão-falso ("false verbena"), evaluating the influences of different growth regulators on in vitro multiplication and rooting stages, as well as examining ex vitro acclimatization of rooted plants. Explants were established on Murashi

6. Propagación in vitro de plantas adultas de Vaccinium meridionale (Ericaceae)
Using stem apex as primary explants, a micropropagation protocol of Vaccinium meridionale was established. During establishment phase the effect of the MS/3, WPM, AND and Kyte media, supplemented with 2-iP plus IAA or BA plus IAA was studied. During microshoot proliferation the effect of MS/3 liquid, solid and double phase (the liquid phase in a solidified p

7. 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.

8. 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

9. VEGETATIVE PROPAGATION OF ERVA-MATE (Ilex paraguariensis Saint Hilaire Aquifoliaceae) / PROPAGAÇÃO VEGETATIVA DE ERVA-MATE (Ilex paraguariensis Saint Hilaire Aquifoliaceae)
A erva-mate (Ilex paraguariensis) assume uma importância ambiental e socioeconômica para a região sul do Brasil, porém carece de tecnologias de propagação vegetativa necessárias para o aumento da produção e da qualidade. O presente estudo teve por objetivos analisar a propagação via estaquia de material adulto e estabelecer a aclimatização ex vi

10. 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

11. Mycorrhizal association on micropropagated plantlets of Jatropha curcas L. / Associação micorrízica arbuscular em plantas micropropagadas de Jatropha curcas L. (pinhão-manso)
The objective of this work was to evaluate the effects of the arbuscular mycorrhizal fungus (AMF), Glomus clarum, multiplied monoxenically in transformed carrot roots, on the growth, survival, mycorrhizal colonization and root development of micropropagated plantlets in different stages of rooting. Inoculation was performed in vitro and ex vitro conditions.

12. IN VITRO AND EX VITRO PROPAGATION OF MATE (Ilex paraguariensis Saint Hilaire Aquifoliaceae). / PROPAGAÇÃO IN VITRO E EX VITRO de erva-mate (Ilex paraguariensis Saint Hilaire Aquifoliaceae).
Mate (Ilex paraguariensis) is an important species in Southern Brazil for its economical and cultural values. The present work had the objectives of analyzing the propagation of mate by cuttings, disinfection and in vitro establishment of nodal segments from adult plants and micropropagation of plants originated from immature embryos. Mate cutting were submi
