Natural Regeneration of (Populus caspica Bornm.) and its relationship with soil physical and chemical properties (Case Study: Safrabaste Region in East of Guilan province)
Abstract:
Populus caspica Bornm is one of the most important tree species in Iranian forest, specially in plain area. Unfortunately, natural regeneration, distribution, and elite trees of this species were diminished by different reasons. In this study, natural regeneration conditions of this species and its relationships with soil properties were carried out in two regions called Parkaposht with poor natural regeneration and Safrabasteh forest park with good natural regeneration. Sampling as unequal linear transect with random harvest of sample pieces has been done. .In each sampling plot, diameter of breast height for each tree, height, and diameter of each sampling and soil sample were taken. The most important soil physical and chemical properties and correlation of them with natural regeneration of important tree species were determined. The results of this study showed that there was strong relationship between establishments of natural regeneration with soil physical properties. The natural regeneration of Populus caspica was established better in light soil texture with good aeration. The establishment of Populus caspica is possible in soils with poor nutrient states, but with suitable physical condition. On the basis of this study, it is declared that establishment of natural regeneration of Populus caspica show strong relationship with soil physical properties compared to the chemical properties of soil.
