Relation between geographical and morphological variations with phytochemical ‎characteristics of Iranian Sumac (Rhus coriaria L.) populations ‎

The aim of this study was to investigate the relationship between geographical and morphological changes on the production of phytochemical compounds in sumac (Rhus coriaria L.) using canonical correlation analysis. Canonical correlation analysis between four environmental variables (height above sea level, slope percentage, latitude, longitude) and 9 morphological traits (collar diameter, number of sprouts, stock height, great crown diameter, small crown diameter, leaf length, leaf width, leaflet length, leaflet width) with phytochemical components was investigated. Samples were collected from five geographical locations in the two provinces of East Azarbayjan and West Azarbayjan. Canonical correlation analysis showed that the samples from higher longitude (numerically higher values) and lands with high slope and low latitude (numerically lower values) had high levels of Ellagic acid 11.49. Results revealed that samples with high leaflet length and low leaf length had high levels of Mallic acid. With increasing leaflet length and great crown diameter, significant decrease in level of Quercetin and Mallic acid hexocide 6.11 was observed.
