摘要: 通过对云烟202旺长期干物质积累和光合生理参数的测定,研究了不同供钾水平下烟叶的干物质积累量和不同光照强度下Pn、Cond、Tr和WUE的光响应。结果显示:不同钾肥施用量对旺长期中部叶位烟叶叶绿素、Pn、Cond、Tr和WUE变化规律相似,即K2>K3>K1>K4>K0。这与干物质积累的变化规律一致。

关键词: 云烟202, 光合生理响应, 供钾水平, 干物质

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
