| Abstract | ||
| The effect of soil and topographic features on distribution of Amygdalus scoparia in Nehbandan (Iran) was investigated. Slope, aspect and altitudinal maps were overlaid to prepare a working map unit. Quantitative and qualitative traits, including height, number, collar diameter of sprout with the highest diameter, crown diameter and trunk health were recorded in 1000 m2 plots (27 plots). In each plot, soil was sampled at depth 0-30 cm. The regression model of the traits with topographical and edaphic factors showed that 70% of variations of A.scoparia sprout height was explained with calcium carbonate, 50% variations of the number of sprouts was explained with clay, and 77% variations of the crown diameter was explained with calcium carbonate. Correlation results revealed that some soil properties such as clay, potassium, organic matter, sand, acidity and lime accounted for A.scoparia distribution. Future work on other indicating factors will help us to determine the optimum range of these factors for this plant species. | ||
