Effect of different treatments on seeds survival and growth of Ziziphus spina -Christi seedlings

The considerable role of Ziziphus spina christi in preserving water and soil and its resistance to heat and drought, the necessity of planting this species for afforestation and restoration of their habitats and urban green space is obvious. The aim of this study was to determine the best irrigation and seedbed treatments before planting for Ziziphus spina Christi seedling production. This study was done in Masjedsoleiman nursery as factorial experimental design with three treatments i.e. scratching the seeds in three levels, the planting bed in four levels, and irrigation in three levels as unbalanced completely random design. The result of analysis of variance showed that the main effects of all treatments (planting bed, method of irrigation and scratching) and their interaction effects on viability percentage were significant (p
