Abstract
The present study was conducted in the forestry department Nursery college of Agriculture summel. during the period of the end of Nov. 2004 to the end of Nov. 2005 to study the effect of the different concentration of GA3 Number and foliar period in growth and development of Quercus infectoria seedling. The study revealed that the concentration 45my/L of GA3 was superiority in all concentrations and gave highest average of the characters length growth dry weight of shoots groups , dry weight Roots groups. Number of lateral roots and rate of shoots: Roots dry weight ratio [ 17.34 cm. 2.31g , 3.25g , 1.58 lateral roots and 0.710]. The four spraying was superiority on the two and three spraying and gave highest average of characters length growth, dry weight shoots groups, dry weight roots group , number lateral roots and rate of shoots: roots dry weight ratio [13.37cm , 1.88g , 2.77g , 1.39 lateral root and 0.669]. Regarding foliar periods the three month period was superiority in all the periods and gave highest average in all characters [12.84 cm , 1.83g , 2.71g , 1.37 lateral roots and 0.665] .
