Jana C., Salvatierra A., Díaz D., Martínez L., Morphological and genetic characterization among wild populations of copao (Eulychnia acida Phil.), cactus endemic to Chile, Chilean Journal of Agricultural Research, 2017, 77(1):3-14, doi: 10.4067/S0718-58392017000100001
The abstract presents a comparison of morphological traits and ISSR markers in three Eulychnia acida populations from Coquimbo. It shows variation within and between populations, and agreement between parts of the morphological and genetic patterns. The publication discusses the usefulness of descriptors for characterising the species' resources.
