Abstract: Zhengdan 958 and Nongda 364 were adopted in this experiment,both contents of chlorophyll and chlorophyll fluorescence parameters of husk leaves of maize(Zea mays L.) varieties at different growing stages were comparatively studied in the field condition.The results showed that chlorophyll content of husk leaves increased at first and then decreased,and reached the peak value values at milk-filling stage.The degradation rate of chlorophyll in husk leaves of Nongda 364 was lower than that of Zhengdan 958 at different growing stages,which was helpful in keeping photosynthetic activities.It was shown that the same diurnal change trend of chlorophyll fluorescence parameters (Fm,Fv,Fv/ Fm,Fv/Fo,etc.) between the two varieties at different stages.Zhengdan 958 had higher chlorophyll fluorescence parameters than Nongda 364,indicating that Zhengdan958 was higher than Nongda 364 in active of PSⅡreaction center,rate of electron transport,efficiency of excitation energy captured by open PSⅡreaction centers.
