Influence of climatic factors on essential oil content and composition of 20 populations of Nepeta binaludensis Jamzad from Iran

Highlights By increasing the altitude, changes in growth and essential oil composition of the plant are observed Result of correlation analysis showed that essential oil yield was positively correlated with precipitation, and negatively with temperature. In the present study the populations with high-amount of nepetalactone and 1,8 cineole were identified, The populations of cluster 2 with higher amount of 1,8-cineole, were growing in the high altitude, cold, rainy and sloping area
