اثر نانو دی اکسید تیتانیوم بر برخی شاخص‌های جوانه‌زنی گیاه روغنی کلزا رقم اکاپی

The present study was done in order to investigate the effect of different Tio2-Nanoparticle concentrations on the some of seed traits such as: The total number of germinated seeds,percentage of germination, germination rate, mean of the time germination, Vigor inde, shoot and root length of the Rapeseed (Brassica napus)plant. Applied concentrations of Tio2-Nanoparticle were 0, 100, 200 and 300 mg.l-1. The experimented was the factorial in completely randomized design with three replication. The results of this experiment showed that the Ag-Nanoparticle concentrations had significantly negative effects on total number of germinated seeds, percentage of germination, mean of the time germination and Vigor inde factors and The highest amount of those traits was belong to control treatment where are the highest negative of Tio2-Nanoparticle was related to 300 mg.l-1 of Ag-Nanoparticle .Overall, results showed all of levels of Tio2-Nanoparticle had negative effects on Rapeseed seed germination indices, such that parameters studied was concentration dependent.
