Abstract

Potassium resulted in high osmotic potential and water potential , low stomatal resistance , increasing chloroplast grana , activities of electron transport and photophosphorylation , activities and contents of Rubisco and Rubisco activase , and net photosynthetic rate .Rubisco is the key enzyme of photosynthesis , and RCA regulates the activities of Rubisco .The contents of Rubisco and RCA in plant leaves sharply decreased with decreasing potassium nutrition , as a results , the initial Rubisco activity , total Rubisco activity and RCA activity decreased . Potassium ion on the activity of pure Rubisco and RCA in vitro was unavailable .The reseach progress about the effect of potassium on photosynthesis and its key enzymes of plant is discussed .
