Abstract

Abstract: To invest igate the effect of rare earth lanthanum ( La) on photosynthesis of Vaccinium plant lets, thechanges of gas exchange parameters, photosynthetic pigment contents and ATPase activity of chloroplast membrane of Vacciniumplantlets were studied after pretreated by different concentrat ions of LaCl3 ( 10, 20, 30 and 40 mg/ L) among oneweek.The results showed that net photosynthetic rate ( Pn),stomatal conductance ( Gs),intercellular CO2 concentration( Ci) and transpiration rate (Tr) were enhanced remarkably in thewhole stage. 7 days after treatment,the contents of photosyntheticpigment, the values of chlorophyll a/ b and ATPase activity were also promoted significantly.The results ind-icate that LaCl3 could improve photosynthetic capacity of Vaccinium plantlets. Additionally, the results showed that 20mg/ L was the optimum concentrat ion of LaCl3 to promote the photosynthesis of Vaccinium.
