The heterogeneity of structural and functional photosynthetic characteristics of mesophyll chloroplasts in various parts of mature or senescing leaf blade of two maize (Zea mays L.) genotypes

Abstract

Differences in ultrastructural parameters of mesophyll cell chloroplasts, content of photosynthetic pigments and photochemical activities of isolated mesophyll chloroplasts were studied in the basal, middle and apical part of maize leaf blade
