Abstract
The effects of waterlogging time in filling stage on photosynthetic characteristics of winter wheat flag leaves were studied,and four waterlogging times were set including 3 d,6 d,9 d and 12 d.The results showed that the photosynthetic performance of wheat flag leaves was reduced by waterlogging.The photosynthetic rate of two species showed a bimodal curve,intercellular CO2 concentration and stomatal conductance showed upward trends,and the stomatal limitation value was declined.Short time waterlogging was advantageous to wheat production at the early filling stage,and long time waterlogging could cause early senescence of wheat.The results could provid the theoretical support for reducing the loss of droughts and floods in north China.
