- Abstract
To understand the nutrient uptaking during and after the waterlogging stress, a pot experiment was conducted to investigate the effects of different waterlogging durations on rapeseed growth and recovery using Brassica napus L. cv Zhongshuang 11. Results showed that the adverse effect of waterlogging on oilseed rape seedling was not only on growth during stress, but also on recovery period after flooding. The leaf nitrogen ( N ), phosphorus (P), potassium (K), iron (Fe), zinc (Zn) and copper (Cu) concentrations were significantly decreased, but the leaf manganese (Mn) concentration was significantly increased with the period of waterlogging lasted. The root N, Fe, Zn, and Cu concentrations were significantly increased, the root P concentration was significantly decreased, the root Mn concentration was significantly increased at 3 d then significantly decreased, and the root K concentration was no significantly diferent during waterlogging. Moreover, in soils, the proportion of nitrate to ammonium and available P concentration were both significantly decreased. Available K, Fe and Zn concentrations were curved. Cu concentration in soils was no significantly diferent during waterlogging but significantly decreased after.
