Effects of mother trees on establishment Juniper seedlings (Juniperus excelsa) in Hezar Masjed forests

In order to investigation effect of mother trees as a nurse plant and slope aspect the study in systematic random designs in Hezar Masjed forests was carried out. Treatments was slope aspect (north, east, south, west) and planting location (under mother trees as a nurse plant, planting in open area) with three replications and 30 seedlings in every replication (in total 720 seedling). In order to investigation effect of these factors annually twice (initial May and October) measurement of survival, height, height growth and collar diameter was carried out. According to results of this research can cited that planting under associated plant species deducted mortality of seedlings in Summer and Winter period, also seedlings height growth planted under nurse plant and open area had no significant with each other. In total due to increase seedlings survival we can plant seedling under associated plant species.
