Abstract :
Abstract Gum tragacanth is one of the most important medicinal and industrial products of rangelands, obtained from the scarification of gum tragacanth-producing Astragalus including Astragalus gossypinus. This species is threatened with extinction due to the non-normative exploitation. This research was aimed to provide a scientific method for the exploitation of gum tragacanth as well as the conservation and survival of this species. The study was conducted in two regions of Isfahan province using a random complete blocks design in a factorial scheme with three replications. Each replication included 30 shrubs that were exploited for the first time. Treatments included the number of scarification and harvesting. The traits included the amount of gum tragacanths obtained from each replication, the percentage of plant mortality, canopy cover, and 1000-seed weight. According to the obtained results, the number of harvesting had a negative impact on canopy cover. The number of scarification and harvesting and their interaction effect on product was not significant. Overall, two scars and four-times harvesting could be recommended for the exploitation of A. gossypinus.
