The Study of Qualitative and quantitative charactristics of Cerasus Mahaleb and relating them to some ecological factors of Khozstan Oak forests

The study was carried out in Khozstan Oak forest located in southwest of Iran. The aim of this study was to determine the Qualitative and quantitative charactristics of Cerasus Mahaleb mill in relation to Some ecological characteristics of site. The plot area was 50×50 m. In this study, 72 sampling plots were taken using random-systematic method. In each plot tree species, physiographic factors and quantitative and qualitative factors of Cerasus Mahaleb (diameter at breast height, total height, trunk height, crown height, crown diameter and degree of quality and regeneration methods were obtained. The collected data were analyzed. The results showed that the Cerasus Mahaleb had the highest distribution on Clay Soil, clay - loam and sandy - clay – loam soil and in the height range 1950 -2450m above sea level, dry slopes (mostly Southwestern) and slopes from 50 to 70 and 30 -50 %. The results of qualitative and quantitative characteristics of Cerasus Mahaleb showed that trees had the poor quality. The average of DBH, the average number per hectare, The average of total height, the average of crown diameter, the average height of crown and the average volume per hectare were respectively 24.27 cm, 16.38, 6.28 m, 3.73 m., 4.57 m and 27.1 m3. Pearson correlation results showed the features of Cerasus Mahaleb such as crown diameter and tree height had a significant relationship with soil depth. The results showed that the diameter at breast height of trees with increasing altitude above sea level has increased.
