چکیده

the effect of tricyclazole application on waterlogging damage alleviation in canola seedlings was evaluated in a pot experiment in complete randomized design layout with three replications. treatments included: control (no waterlogging), waterlogging, tricyclazole plus waterlogging and tricyclazole. tricyclazole (75%) applied at three-leaf stage on canola seedlings. seedlings were exposed to waterlogging at five-leaf stage for 21 days. results showed that waterlogging decreased survived seedling percent, plant height, leaf area, chlorophyll content, total dry weight, root/shoot ratio in comparison with the control. application of tricyclazole plus waterloggging increased leaf area, chlorophyll content, total dry weight in comparison with the control (1.38, 7.11 and 28.9%, respectively) and reduced plant height (12.9%). tricyclazole plus waterlogging increased survived seedling percent, plant height, leaf area, chlorophyll content, total dry weight, root/shoot ratio in comparison with the waterlogged seedlings by 21.2 , 38.91 , 17.5 , 31.56 , 60 and 27.17%, respectively. treatments had significant effect on survived seedling percent, number of dry leaf per seedling, total dry weight, shoot dry weight, stem dry weight, leaf dry weight, leaf area, width of widest leaf and chlorophyll content of canola seedlings (p
