Effects of the cytokinins 6-benzylaminopurine (BAP) and N-2-chloro-4-pyridyl-N'-phenylurea (4-PU-30) on the photochemical activity, oxygen flash yields, and thermoluminescence in bean plants under a water stress were studied. The cytokinins increased the photochemical (Hill reaction) activity and thermoluminescence "B"-band in control as well as in stressed and rehydrated plants, while the oxygen flash yields were affected only in the stressed and rehydrated plants.

Additional key words: oxygen flash yields; photochemical activity; photosynthesis; photosystem 2; thermoluminescence
