Effect of edaphical factors on oak sprouting ability

Abstract

This research was carried out in the Doveyse Forest with an area of 660 hectare, located in northern-east of Marivan city, Kurdistan Province, Iran. Totally 103 plots were designed using a systematic random rectangular grid with dimensions of 150m × 300m. Sprouting situation of oaks was studied in the plots. Based on plant ecological groups' map and physiographical factors, site homogeneous units were determined and soil samples were prepared from these units. The effect of the most important edaphical factors (totally 12 factors) were analyzed using PCA in the main aspects. The results showed that the most important factors affecting sprouting of oaks in north aspects are pH and electrical conductivity, and in south aspects PH and potassium content of soil are the factors that play a crucial role.
