Abstract
Waterlogging stress induces harmful physiological changes which restrict canola growth. The aim of this investigation was to evaluate the effects of foliar applications of nitrogen compounds (urea, calcium nitrate and potassium nitrate) and tricyclazole at different growth times on physiological responses in canola plants (Brassica napus L. cv. Hayola 401) subjected to waterlogging stress. Plants in the 5-leaf growth stage were exposed to waterlogging conditions for two weeks. Results of waterlogged control compared to non-waterlogged control demonstrated that waterlogging stress significantly decreased the activity of superoxide dismutase (SOD; EC 1.15.1.1), catalase (CAT; EC 1.11.1.6) and peroxidase (POX; EC 1.11.1.7), while lipid peroxidation and ethylene production in the leaves were increased by the waterlogging stress. Furthermore, dry weight and length of shoots and roots were reduced by waterlogging stress. These adverse effects of waterlogging stress were alleviated by foliar application of all tested compounds; once (before the stress) or twice (before and after the stress). Twice foliar applications did not have any significant superiority to once foliar spray. It was concluded that, among the different treatments, the foliar spray of calcium nitrate, potassium nitrate and tricyclazole before the waterlogging stress were more beneficial and cost efficient than the twice application and is advisable to alleviate the waterlogging damage in canola.
