AbstractThe study was performed in Horticulture lath house / college of Agriculture & Forestry, University of Mosul to investigate the effect of seed soaking in three concentration of both KNO3 (0, 1000 , 2000 and 3000 mg.l-1 ) and hypertonic (0, 1 and 2 cm3.l-1 ) for 48 hrs and their interaction treatments on percentage germination seed and seedlings growth of "Lotus" persimmon rootstock. Then the seeds stratified in peat moss and sand in nylon bags at 5°C for 100 days. After the period of stratification, the seeds were planted in black polyethylene bags in the lath house on 20th of March, 2010. Parameters of seeds germination and seedling growth were recoded. The results were as follow: Interaction between 2000 mg.l-1 KNO3 and 2 cm3.l-1 hypertonic gave the highest germination of the seeds (85.71%), and Interaction between 3000 mg.l-1 KNO3 and 1 cm3.l-1 hypertonic resulted in a significant increase in seedlings height and diameter and leaves number per seedling as compared with control treatment, while the interaction treatment between 3000 mg.l-1 KNO3 and 2 cm3.l-1 of hypertonic was superior in leave surface area.
