Abstract : |
In order to determine the initial growth and development of direct-seeded Caucasian oak (Quercus castaneifolia C.A. Meyer) seedling an experiment was carried out using the completely randomized design on three soils, of low (soil L), medium (soil M) and high (soil H) nutrient contents in elm-oak stands of the northern Iran. The results at the end of the first growing season demonstrated that values in most of characteristics measured statistically differed among soils. Survival rate, stem length, root length, apical shoot length, node number on the apical shoot, stem dry weight, leaf area and specific leaf area were greatest on soils H. Collar diameter and growth flush number did not differ among different soils. Likewise, nutrient elements in stem, root and leaf were mostly greatest on soil H. Generally, from this research it is deduced that in the elm-oak stands higher fertility soils are more favorable for growth and development of oak seedlings when using seed sowing., |
