بررسی مسایل و مشکلات تولید نهال کلیر‭(Capparis decidua)‬

The plantation of natire species in regions which face desertification and mobile sand dunes has proved rery efficient in the success of desertifu:ation projects. main becaus these species can endure natural stresses. Cappanis decidua seedling has a suitable vegetative form sand so, can reduce wind speed and the movment of mobile sand dunes. This species is adjusted to the heavy soils of eastern jaunouritJn sand hills and mainly prefers these soils. the sprouting ability of this species has facilitated the survival of this species in regio1l.v the destruction and cuting of the plants are widespread. so, positive charecteristics of this species including resistance against natural stresses and utiliz.ation systems have paved the road to use it in the reclaimation of desert regions. to do so many attempts have beena done to dervlope its plantation, but so far the attempts to grow its seedlings and transfering them to the sites have failed. In this study the problems and constraints of growing capparis decidua seedlings have been in vestigated. the tests have been carriedout in the natural growing sites and the forestry and ranges research institute laboratory
