1. Feasibility of the new method for orchid in vitro rooting using liquid and chemical sterilized culture medium under different sucrose concentration
Resumo A propagação in vitro de orquídeas é a única técnica comercial em larga escala para obtenção de plântulas saudáveis e de alta qualidade com origem clonal. O uso de novas tecnologias em sistemas de cultura de tecidos vegetais pode levar a aumentos de eficiência e redução de custos dos sistemas de micropropagação. O principal sistema de m

2. Storage and in vitro germination of orchids (Orchidaceae) seeds from Atlantic Forest – Brazil
Abstract: The orchid seed banks of Atlantic Forest may be considered a key strategy for the conservation of species threatened with extinction by indiscriminate collection or habitat destruction. The aim of this study was to evaluate the seed viability, to choose the best culture medium for the asymbiotic germination and evaluate germination, after storage f

3. In vitro culture and acclimatization of Cattleya xanthina (Orchidaceae), an endangered orchid of the Brazilian Atlantic Rainforest
Resumo Cattleya xanthina é uma orquídea neotropical endêmica da Mata Atlântica brasileira, com alto risco de extinção. Neste trabalho analisamos diferentes meios de cultura sobre o desenvolvimento de C. xanthina, e seu status de nitrogênio endógeno. Meios de cultura estudados: Knudson C (KC), Vacin & Went (VW) e Murashige & Skoog (MS), e o meio MS co

4. Bioprospecting and selection of growth-promoting bacteria for Cymbidium sp. orchids
ABSTRACT: Inoculants containing bacteria which promote growth in plants can increase productivity and both the economic and the environmental cost in plant crop systems. Similarly, in the flower and ornamental plant sector, the use of diazotrophic bacteria is a promising approach for improving orchid propagation from tissue culture to the ex vitro environmen

5. Reguladores de crescimento no desenvolvimento de orquídeas terrestres cultivadas em vasos
As orquídeas têm aumentado seu espaço no comércio interior e nas exportações dentro da área de floricultura. Entretanto, algumas espécies de orquídeas apresentam problemas devido ao seu porte elevado, o que dificulta seu cultivo em vasos, sua comercialização e transporte. Os reguladores de crescimento são substâncias químicas sintéticas usadas

6. Mycorrhizal diversity in Coppensia doniana (Orchidaceae) and phylogeny of mycorrhizal fungi associated with the Oncidiinae subtribe / Diversidade micorrízica em Coppensia doniana (Orchidaceae) e filogenia de fungos micorrízicos associados à subtribo Oncidiinae
In nature, orchids are fully dependent on mycorrhizal fungi for germination. These fungi can penetrate root cells and form pelotons, whose digestion provides simple sugars for the embryo. During the achlorophyllous seedling stage, orchids are obligatory dependent on the fungi, and some species remain so through life, while others become facultatively respons

7. Extrato pirolenhoso no cultivo de orquídeas
The use of pyroligneous extract in the cultivation of plants is improvement of development. The effect of the use of different shot of pyroligneous extract in vegetative of two orchids of the gender Cattleya was studied in greenhouse. Used plants Cattleya intermedia Lindl and Cattleya loddigesii Lindl, grown in pots containing substrate composite coconut fib

8. Orchidaceae nativas da região central de São Paulo, Brasil : florística, interação com forófitos, proposta de novas espécies e propagação in vitro de uma espécie ameaçada de extinção / Native Orchidaceae of the central region of São Paulo, Brazil: floristic, interaction nested with host tree, new species proposed and in vitro propagation of threatened of extinction species
Aiming to know the sorts of Orchidaceae of the central region of the State of São Paulo, from 1996 and more intensively from 2005, visits were carried out in 125 forest fragments of 23 local municípios, with weekly periodicity and also, fortnightly. The collect were assistematics, being each fragment visited in the biggest number of points. The species not

9. Substratos alternativos ao xaxim para o cultivo de espécies do gênero Cattleya (Orchidaceae)
The use of alternatives beds for xaxim on culture of ornamental plants is a mean to contribute on environmental preservation, but it depends of studied vegetal specie and kind of ambience. Present work had the purpose to evaluate efficiency of different beds by vegetal origin, to grow species of orchids (Orchidaceae). Seedlings of Cattleya loddigesii, Cattle

10. Light and sucrose in micropropagation of Cattleya walkeriana: Anatomic and Physiologic changes / Luz e sacarose na microporapgação de Cattleya walkeriana: alteraçõies anatômicas e fisiológicas
Cattleya walkeriana ia a orchid of great decorative value. The use of micropropagation techniques are important issues in the reproduction of that specie. The use of conventional techniques of micropropagation causes plantlet losses during the acclimatization process and also promotes a high energy consumption in growth rooms which finishes by increasing the
