Sažetak
Drought is the second most important cause of yield loss after low soil fertility. Aim of this study was to investigate changes in chlorophyll a fluorescence parameters of maize subjected to drought stress during tasseling. Results have shown that all selected parameters in drought stressed maize differ significantly from control. Negative effects can be placed in three groups: inactivation of reaction centers turning them into heat sinks (decrease in RC/ABS, increase in DIo/RC), impairment of OEC (oxygen evolving center) (increase in F300), decrease in electron transport efficiency and related problems in QA (primary quinonce acceptor) and plastoquinone oxidation.
