Abstract

This research was carried out in Chitgar FOREST PARK, located in west of Tehran with an area of 1450 hectars.For determining the effects of pruning on VITALITY of PINUS ELDARICA Medw. Under WATER STRESS, pruning trial was done under Completely Randomized Block design with four Treatments (sever, moderate, light, control) and four replicates. The Replicates were selected on four sites with different ecological conditions and maintenance managements.The definition of the PRUNNING treatments were as follows:1- Severe: All of the branches were prunned from crown bottom up to two meters.2-Moderate: All of the branches were prunned from crown bottom up to one meter.3-Light: Only the dried, infected and less than two cm diameter branches were prunned.4-Control: Without pruning, except the dried branches at the low level of the crown.Inventory has been done at two times, before PRUNNING and one year after PRUNNING. Statistical analysis was done using SPSS software. The results show that PRUNNING the effects of the treatments and the replicates on trees VITALITY were significant at 0.05 level. The sever PRUNNING had the greatest effect on VITALITY when WATER STRESS was very high and SOIL productivity was very low. Light PRUNNING had the most effect on VITALITY in fertile sites with regular irrigation, but the moderate PRUNNING had the most effect on pine VITALITY in seme-fertile site under moderate WATER STRESS.
