In addition to other photosynthetic processes, chlorophyll fluorescence can be a good Indicator of the altered status of photosynthetic apparatus occurring due to dehydration of plant tissues (1). Chlorophyll fluorescence yield in vivo under normal physiological conditions is mostly a function of two types of fluorescence quenching, photochemical and non-photochemical (2).It was shown that contribution of photochemical and non-photochemical quenching to the total fluorescence quenching in the leaves tended to vary during drought and was likely to suggest the functional alterations incurred due to tissue dehydration (3). The present paper will concentrate on the investigations of water status and fluorescence quenching in two maize lines differing in drought resistance and abscisic acid accumulation (4).
