Key words: Brassica napus, Gibberllic acid, Chlorophyll, Shoot length.
In order to study the effects of Gibberellic acid (GA3) foliar on brassica napus L. the experiment was carried out in Research Laboratory and research field of Islamic Azad University of shahr-e-Qods in randomized completely design and randomized completely block design with 3 replications and 3 treatments such as: 1: control (water), 2: (GA3, 0.0001 molar), and 3: (GA3, 0.001 molar) which seeds were foliar at 45 minutes in GA3 these solutions. The result showed that there was significant difference at 5% level among treatments such as seedling length, ratio of root length to shoot length, chlorophyll (b) and fresh weight at 1% level and enhance of total chlorophyll. But among treatments there was no significant difference in germination percentage, root length, chlorophyll (a), dry weight and seed vigor. Also the resumed result of field section showed that there are not significant differences among treatment such as final emergence percentage, shoot length, MDG and DGS, but with considering the comparison of means table (table 4) the use of Gibberellic acid caused to enhance of shoot length.
