| Abstract | ||
| This study was carried out in the Nursery of the college of Agriculture / University of Duhok / Kurdistan region/Iraq during growing seasons 2013 to study the effect of shading, seeds storage methods and GA3 treatments on nutritional status and chlorophyll content of loquat seedlings. Shading percentage (direct sunlight and 50 % shading), three methods of storage, without storage (direct planting), one month in refrigerator and one month in room condition) and three concentration of GA3 (Zero, 250, 500 mg/L-1). Results obtained that the room storage significantly increased N percentage in leaf, whereas the both sunlight and 500 mg.L-1 GA3 effect significantly on the chlorophyll content ,P and K percentage in the leaf of Loquat seedling ,while refrigerator significantly increased chlorophyll content in the leaf. The interaction between the studied factors also significantly affected on the nutritional status and chlorophyll content of loquat seedlings, the interaction of sunlight + room storage + 500 mg.L-1 GA3 was the best treatment. | ||
