Abstract

Today, Zagros Reforestation is more than ever felt due to human presence and its destructive activities. To do this requires observing the scientific principles of silviculture. Of essential restoration activities in these forests can be mentioned the seed planting of indigenous species within their range of development. In this regard, the present research was conducted with the aim of investigate the germination and emergence status of Quercus persica, Pistacia atlantica and Acer cineracens seeds planted in Dalab Ilam forests in 2018. For this, three sites on the northern slope and approximately the same height of 1380 to 1410 meters above sea level were selected. In each site, three trees were considered for each of Q. persica, P. atlantica and A. cineracens species. Under each tree, three holes were drilled between the trunk and the end of the crown for each crown side, and a total of 12 holes. In drilled holes under the trees, the corresponding seeds were planted in the winter 2017. The results of the sampling in the spring 2018 showed that the seeds of Q. persica had the highest emergence rates (22%). The seeds of P. atlantica gained the second rank in terms of germination and emergence (18%). The seeds of A. cineracens had the lowest amount of emergence (0. 3%) and the number of emerged seedlings was rare. The highest occurrence rate of Q. persica seedlings was on the northern side of tree crown (32%) and in for P. atlantica was on the southern (32%) and western (30%) sides of the tree crown. The highest rate of seedling emergence of Q. persica (48%) and P. atlantica (51%) was found at nearest distance to tree trunk. Despite planting the seeds of these three tree species in the same conditions in terms of topography, position under the crown and distance from tree trunk, similar results were not obtained which the reason of this can be attributed to their seed characteristics such as seed size and seed vigor.
