Evaluation of Salsola rigida populations in different ecological zones of Semnan province

Most of the rangelands in Iran have been destroyed and a main part of rangeland plants are threeatened or their populations are reduced. In order to stability, reclamation of rangeland with adaptable species and finding the best cultivation method are of special priority. The present study was done to evaluate the stablishment percentage of Salsola rigida populations in different vegentation regions of Semnan provionce. Based on the results of reasearch project, seeds were collected and cultivated from different regions of the rangelands. For determination of population stablishment percentage, a randomized completelty block design were conducted in triplicate under farm conditions between 2013-2015 and the data were analyzed. Among the accessions, the genotype code 232 (originated from Chahakeh 6, Haj Ali Kavir) and 229 (originated from down road, Alay Village) had the highest and lowest stablishment percentage, respectively. Findings of the present research illustrated that genotype code 232 of S. rigida can be used for reclamation of rangelands in the study area.
