Root anatomy of nine orchidaceae species
Studies on the root anatomy of nine Orchidaceae species presented a multisseriated velamen, a parenchymatous cortex and a definided endodermis, in all the studied species (Catasetum fimbriatum Lindl., Dichaea bryophila Rchb. f., Encyclia calamara(Lindl.) Pabst, Epidendrum campestre Lindl., Epidendru...

| Summary: | Studies on the root anatomy of nine Orchidaceae species presented a multisseriated velamen, a parenchymatous cortex and a definided endodermis, in all the studied species (Catasetum fimbriatum Lindl., Dichaea bryophila Rchb. f., Encyclia calamara(Lindl.) Pabst, Epidendrum campestre Lindl., Epidendrum secundum Jacq., Miltonia flavescens Lindl., Pleurothallis smithiana Lindl., Stanhopea lietzei (Regel) Schltr. and Vanda tricolor Lindl.) Structural characters, which could be considered root adaptations to an epiphytic habit, were also common for all species.<br>As raízes possuem um velame multisseriado, um córtex parenquimático e uma endoderme bem definida, em todas as Orchidaceae estudadas (Catasetum fimbriatum Lindl., Dichaea bryophila Rchb. f., Encyclia calamara (Lindl.)Pabst, Epidendrum campestre Lindl., Epidendrum secundum Jacq., Miltonia flavescens Lindl., Pleurothallis smithiana Lindl., Stanhopea lietzei (Regel) Schltr.e Vanda tricolor Lindl.). Caracteres estruturais, que podem ser considerados adaptações ao hábito epífito, são comuns nas raízes estudadas. |
