| Abstract | ||
| This experiment was carried out in the Nursery of Agriculture college / University of Duhok / Kurdistan region/Iraq during growing seasons 2012-2013 to investigate the effect of shading, seeds storage and GA3 treatment on seeds germination and growth of loquat seedlings. Shading percentage (Non shade and 50 % shading), three treatments of storage, (direct planting, storage one month in Fridge and storage one month at room temperature) and immersion in three concentrations of GA3 (Zero, 250, 500 mg. L -1). The results of this study indicated that shading, storage and GA3 concentrations affected significantly on the percentage germination of seeds as well as the shading affected significantly on the Loquat growth (seedlings length, seedlings diameter, leaves number, wet weight and dry weight of vegetative growth and root fresh weight and dry weight of roots and root length)while the Storage and GA3 effected significantly on seedlings diameter). The interaction of shading + direct planting + 500 mg.L-1 of GA3 affected in percentage germination of seeds and leaves number. The interaction of shading +Fridge storage + zero mg.L -1 of GA3 had highest seedlings length and seedlings roots length, whereas the interaction of shading + room storage + 25o mg.L -1 of GA3 overtopped in seedlings diameter. | ||
