This study was conducted to investigate the effect of seed wight ,scarification and chilling at - 6±2 c for three period vis .

0 ,24 and 48 hour .The results revealed the superior of the seed weight 40-45 mg in alls character studied and gave high average of germination energy ,germination percentage , seedling length numbre of leaves and dry weight of stem and leaves (53.82%,32.80% ,29.25 cm,23.27 and 3.42 gm,4.34 gm).

The scarification seeds showed superiority in all characters except the dry weight of stem and giving highest averge of germination energy 51.62% germination percentage 35.12 %,seedling length 28.41 cm number of leave 24.41 and dry weight of leave 5.10 gm .

The chilling period 48 hour was superioir in alls character germination energy 51.18% germination percentage 35.53% , seedling length 32.12 cm , number of the leave 26.56 ,dry weight of stem3.12 gm and leave 4.70 gm .

The interaction weight 40-45 mg scarification, interaction weight 40-45 mg chilling period 48 hour, The interaction scarification and chilling period 48 hour were the best interactions in all characters.
