J. Dorr SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTIONEmphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: In these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institutions throughout the world.Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affiliation with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines. General requirements for manuscript preparation are on the inside back cover of printed volumes.

“…It is an ornamental species popular among consumers owing to its numerous yellow flowers distributed along the flower stem. It is commonly used in floriculture, marketed as a potted plant or cut flower, and for landscape projects (GARAY; STACY, 1974;LORENZI;SOUZA, 2001;FARIA et al, 2006).…”

An adequate concentration of growth regulators as well as the replacement of agar by an alternative medium may be promising from practical and financial points of view to produce orchid plants by micropropagation. The objective of this work was to evaluate different concentrations of growth regulator and alternative substrates for agar replacement in culture medium for in vitro multiplication and rooting of Oncidium baueri. In the explant multiplication phase, two experimental factors were evaluated-various concentrations of 6-benzylaminopurine (BAP) (0.0, 1.0, 2.0, and 3.0 mg L -1 ) and substrates (agar, vermiculite, and coconut fiber) added to MS medium. In the rooting phase, different concentrations of indole butyric acid (IBA) (0.0, 0.5, 1.0, and 1.5 mg L -1 ) were added to culture medium containing the same substrate. Six months after the experiments were initiated, the survival percentage, number of leaves, shoots, and roots and length of the aerial part and the major root were evaluated. The results suggested that addition of 1.0 mg L -1 BAP is necessary for the O. baueri in vitro multiplication phase, but IBA is not necessary in the rooting phase. For the substrate, vermiculite is not indicated as an agar replacement. In contrast, coconut fiber can be used in both multiplication and rooting phases of Oncidium baueri in vitro culture. Key words: Orchid. Coconut fiber. Culture medium. Vermiculite. ResumoNa micropropagação de orquídeas, a concentração adequada de reguladores de crescimento, bem como a substituição do ágar por substratos alternativos no meio de cultura podem ser promissoras do ponto de vista da praticidade e da economia financeira para a obtenção de mudas. Assim, o objetivo do trabalho foi avaliar diferentes concentrações de reguladores de crescimento e substratos alternativos em substituição ao ágar no meio de cultura para a multiplicação e o enraizamento in vitro de Oncidium baueri. Na fase de multiplicação dos explantes, foram avaliados dois fatores: concentração de benzilaminopurina (BAP) (0,0; 1,0; 2,0 e 3,0 mg L -1 ) e substrato (ágar, vermiculita e fibra de coco) no meio de cultura MS e, no período de enraizamento, foram testadas concentrações de ácido indolbutírico (AIB) (0,0; 0,5; 1,0

Introduçãogêneros Oncidium e Odontoglossum (Dressler 1981(Dressler , 1993. A polinização é realizada por insetos (Dressler 1993).Por se tratar de uma das maiores famílias vegetais e por ter origem filogenética recente (Terciário Inferior), Brieger (1971) baseou-se na evolução filogenética e distribuição geográfica de espécies de orquídeas, assim como em espécies das famílias Araceae e Cactaceae, para tirar conclusões sobre ocorrências geológicas durante períodos geológicos anteriores, em regiões tropicais. Brieger (1961, 1976) utilizou a família Orchidaceae para estudar evolução nos trópicos, já que são muito freqüentes nessa região e apresentam grande Revta brasil. Bot., São Paulo, V.24, n.4 (suplemento), p. 553-560, dez. 2001 ABSTRACT -(Intraspecific variability in five populations of Oncidium varicosum Lindl. (Orchidaceae -Oncidiinae) in Minas Gerais). Five populations of Oncidium varicosum Lindl. (Orchidaceae -Oncidiinae) collected in Minas Gerais at Alfenas (AL), Estiva (ES), Pouso Alegre (PA), Pedra do Coração (PC) and Pedra Branca (PB), were examined with the aim of studying the intraspecific genetic variability. Twenty-two floral characters were measured from vouchers, using univariate and multivariate statistical methods (canonical discriminant analysis -CDA and cluster analysis using Mahalanobis distance). Significant differences (p < 0,05) among populations, by the F test, were observed for 13 characters. The first canonical axis separated population AL from PB and PC. The PA individuals are smaller than those of PC, which are smaller than those of PB. AL overlapped PA, ES and PC by the first axis, but was completely separated from PA and almost totally from the other populations according to the second canonical axis, for presenting characteristics such as longer and thicker columns, longer and narrower lateral sepals and shorter ovaries. According to the cluster analysis, AL diverged again from the other populations. Populations ES, PC and PB are closer to each other, followed by PA. The pattern of genetic variability observed does not seem to be related to different latitudes. However, it seems to be associated to longitudinal differences, although this single factor may not be enough to explain this pattern. RESUMO -(Variabilidade intra-específica em cinco populações de Oncidium varicosum Lindl. (Orchidaceae -Oncidiinae) em Minas Gerais). Com o objetivo de estudar a variabilidade genética intra-específica em Oncidium varicosumLindl. (Orchidaceae -Oncidiinae), foram avaliadas cinco populações de Minas Gerais, coletadas em Alfenas (AL), Estiva (ES), Pedra do Coração (PC), Pedra Branca (PB) e Pouso Alegre (PA). Foram considerados 22 caracteres florais, medidos a partir de "vouchers" (fichas florais), empregando-se métodos estatísticos univariados e multivariados (análise discriminante canônica -CDA e análise de agrupamento a partir de distância de Mahalanobis). Houve diferença significativa (p < 0,05) entre populações, pelo teste F, para 13 caracteres. O primeiro eixo canônico separou a população...
