Induction of polyploidy in plants powerful tool to achieve the goal of increasing performance. To fulfill this purpose of using chemical substance trifluralin in concentrations of 7.5, 15 and 22.5 and four times of 8, 12, 24 and 48 hours. The results showed that concentrations of trifluralin interaction between time and concentration of treated plants had a significant impact survival percentage so that the highest survival rate is related to the concentration of 7.5 and 8 hours.
