The Effect of Different Treatments on Seed Survival and Seedlings Growth of Ziziphus numularia

Ziziphus numularia is drought-resistance plant species. This study aims at identifying the best irrigation and seedbed treatments before planting for Ziziphus numularia seedling production. This study was carried out in Masjedsoleiman nursery as factorial experimental design with three treatments i.e. the planting bed in four levels, irrigation in three levels and scratching the seeds in three levels, as unbalanced completely random design. The results demonstrated that the main effects of all planting bed treatments and their interaction with irrigation effects on all traits (except length of stem) were significant. In different methods of seed scratching, for all traits were not significant. Also for traits including the dried weight of root, survival percentage and length of the root had the most importance respectively. As for the treatment effects, the treatment combination of every day watering in soaking seeds for 48 hours in general soil had the most survival percentage.
