Abstract: The responses of photosynthetic physiology parameters inclunding net photosyn-thesis( Pn), stomatal conductance( Cond), transpiration( Tr) and water use efficiency( WUE) of Yunyan202 to different K fertilizer treatment were investigated.The results showed that: The rule of different K fertilizer treatment on the chlorophlly content,net photosynthesis( Pn), stomatal conductance( Cond), transpiration( Tr) and water use efficiency ( WUE) was similar, namely K2>K3>K1>K4>K0.This is similar with dry-matter accumulation.

Key words: Yunyan202, Photosynthetic physio-response, Potassium fertilizer, Dry matter
