Abstract
Within research project “Taxonomy, Ecology and Utilization of Carob tree (Ceratonia siliqua L.) and Bay Laurel (Laurus nobilis L.) in Croatia” (HRZZ-IP-11-2013-3304), a total of 1200 plant samples were collected from 12 distinct populations of bay laurel in Croatian Adriatic area. After morphometric analyses of leaves, AFLP analyses of genetic variability, and variability of total essential oils content in leaves of bay laurel populations, significant correlation between leaf surface and essential oils content (Spearman’s Rank Order Corr. Coeff. rs = 0.15 ns) was not found, while the correlation between latitude and essential oils content was strongly negative (Spearman’s Rank Order Corr. Coeff. rs = - 0.78; p
