摘要
在田间栽培条件下 ,小麦旗叶的气孔导度、净光合速率与钾之间呈显著的正相关。钾可减少由于光合“午睡”造成的2 6 .5 %～
Under the field condition,stomatal conductance or photosynthetic rate of wheat flag leaves and potassium showed an obvious positive correlation. Potassium could reduce 26.5%～37% lose of photosynthetic rate caused by midday depression.
