Genetic diversity of Vriesea cacuminis (Bromeliaceae): an endangered and endemic Brazilian species

Genetics and Molecular Research, 2013
Data about the genetic structure can help to understand the evolutionary process of natural populations as well as to drive strategies of conservation. Vriesea cacuminis, an endemic Brazilian Bromeliad, has been found in 2 areas of Minas Gerais State. One is a legal preservation unit (Ibitipoca State Park) and the other an unprotected area (Serra Negra)

Effect of sucrose concentrations on in vitro growth and subsequent acclimatization of the native bromeliad Vriesea inflata (Wawra) Wawra

Biotemas, 2015
Using sucrose is crucial for in vitro plant growth, due to decreased photosynthesis under this condition. However, ornamental epiphytic species, which have slow growth, have shown better development in nutrient media with low concentrations of this ...
