Among photosynthetic processes, Photosystem II (PSII) evaluated by chlorophyll fluorescence technique is believed to be the most sensitive to stress (Goedheer 1972; and others). Response to drought and nitrogen (N) stresses involves morphological, physiological and metabolic processes. Understanding these processes may improve the efficiency of selection for drought stress. But an important key is finding precise measures of these processes that are relatively easy and quick to take. The goals of this research were to demonstrate that apparent electron transport rate, as measured by chlorophyll fluorescence, can be used as a measure to discriminate among maize (Zea mays L.) genotypes and to determine if the response to drought- and N-induced stresses differed between a set of older hybrids compared to current, elite hybrids.Collection: CIMMYT Publications Collection
