Morphometric characteristics of Galium odoratum L. (Scop). from Bulgaria
The aim of the study is to analyze the morphometric parameters of 10 populations of Galium odoratum from Mala Planina and Ponor Mountains (Bulgaria), in accordance with the specific conditions of their habitat, and to define the similarity between their morphological characteristics by cluster analysis.
The majority of the studied morphometric parameters show a medium degree of variation between populations. Cluster analysis showed differences between the individual populations between 0 and 38%. The highest similarity was detected between the populations from habitat M-II-1 CD-2,3. With the soil humidity being the main difference between the habitat types, the analysis shows its strong role in the formation of biomass in Galiumodoratum.
