\textbf{Abstract}
\begin{abstract}
\normalsize{
The standard germination test is a seed viability test in best situation for germination and showed speeds of germination only. For these reasons used the other laboratory test such as the accelerated aging and the cold test, subject seeds to stress as means of determining their suitability for planting. The results obtained from previous studies showed that vigour tests could provide better results for ranking the quality and for indicating planting value of seed lots than the standard germination test. This research in order to study effects drought stress and planting dates on original plant on product seeds vigour from its by Accelerated Ageing Test (AAT), was performed in Laboratory of the Department of Agronomy and Plant Breeding of College of Aboureyhan in Pakdasht during spring 2008. Accelerated Aging Test was accomplished with 20 treatments and 3 replications. These 20 treatments were the seeds of 5 cultivars of canola (Licord, Opera, Modena, Elite, Sarigol), 2 levels of planting dates (First half October and first half November) and 2 levels of irrigation (80 mm evaporation from class A pan and drought stress from stem elongation stage) which in year 2006--2007 had been cultivated in a factorial split plot based on RCBD. In Accelerated Ageing Test: Final Germination Percentage (FGP), Mean Time to Germination (MTG), Mean Daily Germination (MDG), Daily Germination Speed (DES) and Abnormal Seedling (AS) were measured. Based on the laboratory results, the cultivar of Sarigol due to higher MDG and lower MTG, DGS and AS had higher seed quality and vigour.}
