Autecological characteristics of dog rose and hawthorn in using canonical correspondence and detrended correspondence analysis in East Azerbaijan Province, Iran

This research aimed to study the needs of habitat and ecological characteristics of two species of medicinal ornamental plants included dog rose and hawthornusing multi-variale regression canonical correspondence (CCA) and detrended correspondence analysis (DCA) for development of urban green space in East Azerbaijan province. Totally, 52 of mentioned plants soil samples were collected from East Azerbaijan, Iran and their habitat and physiographical characteristics such as slope, orientation and altitude and edaphic characteristics of collection site such as pH, EC, soil texture, lime percentage and soil fertility factors were recorded. Collected ecological were analyzed using PC-ORD software based on multivariate regression analysis of CCA and DCA. Increasing of soil phosphorus and decreasing of slope tend to density of hawthorn. The least pH was found in hawthorn soils. Also, hawthorn and dog rose growing areas were in north orientation and in soils with light texture and high drainage. Both plants had almost the same ecological needs. Therefore they can be planted in landscapes of urban and downtown in combination.
