Abstract: The chlorophyll fluorescence parameters change of the Penstemon was studied,the aim was to enhance its planting management for the region in east China. Chlorophyll fluorescence parameters [minimal fluorescence(Fo),maximum fluorescence (Fm),photochemical quenching (qP),variable fluorescence (Fv),yield(Y),non photochemical quenching(NPQ),and electron transport rate (ETR)] of Penstemon campanulatus Purple Passion,Penstemon digitalis Husker Red,and Penstemon barbatus Rondo,all perennial root flowers,were measured and compared by the chlorophyll florescence measuring technique. A correlation analysis was conducted. Results of the correlation analysis showed significant positive correlations between Fo and Fm,qP and Fm,qP and Fv,Y and ETR,Fm and Fv,Fo and F,and Fm and Y;significantly negative correlations were found between Fo and ETR and Fv /Fo and Y. Also,chlorophyll fluorescence parameters for the three cultivars were significant(P = 0.05) and highly significant (P = 0.01). The values of Fv,Fv /Fm,Fv /Fo,Y,ETR,qP,and NPQ for the three cultivars were in the order:Purple Passion RondoHusker Red. Thus,the photosynthetic physiological functions of P. campanulatus Purple Passion were best.[Ch,1 fig. 3 tab. 16 ref.]
