Abstract EN

This study was conducted in the lathhouse of the Techinques of plant production department / Technical college / Musaib during 2007-2008 ; to find out the impact of seed storage (without storage, 30 days in the refregirator and 30 days on room temperature) as well as some chemical treatments (Sodium hydroxide at 0.4, 0.6 and 0.8 N and gibberillic acid at 150, 300 and 450 mg / L) on seed germination, and the effect of seedling spray with Prosol 0, 2 and 4 g / L and garlic bulb crud 0,5 and 10 cm3 / L, as a factorial in CRD and RCBD with 3 riplication.

The results indicated that higher germination 74.88 % resulted from unstord seed, reduced germination period to 24.17 day.

theses seeds as well as seeds stored in 30 days in the refregarator gave highest seed germination rate 2.45 and 2.60 day respectively,.Sodium hydroxide 0.8 N and gibberellic acid 450 mg / L gave higher germination percentages 78.98 and 80.43 % respectively and retes 1.90 and 1.79 day respectively and reduced germination period 23.77 and 23.12 day respectively, as compared to the control treatment which resulted 57.70 %, 3.70 day and 34.02 days respectively.

The interaction of high concentrations of gibberellic acid or Sodium hydroxide with nonstorage treatment resulted in increasing of germination percentage 88.27 and 86.55 and germination rate 1.16 and 1.47 day, reduced germination period 17.24 and 20.62 day as well.
