Abstract

The aim of this study was to investigate morphological diversity and canonical correlation analysis between four environmental variables (altitude, slope, latitude, longitude) and 10 plant characteristics (collar diameter, number of sprouts, diameter at breast height, main stem height, large crown diameter, small crown diameter, leaf length, leaf width, leaflet length) in sumac (Rhus coriaria L.). Plant samples were selected from five geographical locations with unique features in two provinces of East and West Azarbaijan. According to the results of descriptive statistics, the highest coefficients of variations were observed for diameter at breast height (61%), number of sprouts (52%), collar diameter (40%) and the lowest one was observed for leaf width (21%). The highest sprout was found in the plants sampled from Nizhdarreh that can be due to its bad growth conditions. Canonical correlation analysis revealed that with increasing the amounts of latitude and reducing the amounts of slope and longitude, the length of leaves increases.
