In vitro germination and development of two endangered endemic Colombian orchids Cattleya mendelii and Cattleya quadricolor

Cattleya mendelii and C. quadricolor are endemic orchids from Colombia, which have been subjected to extraction from their natural environments for commercial purposes, becoming critically endangered. However, there is no sustainable management practice for the conservation of these species. The aim...
