Al3+ in combination with kinetin showed more protection against degradation of chlorophyll (Chl) and protein than Al3+ or kinetin alone during dark-induced senescence in wheat primary leaf segments. MV-dependent whole chain electron transport, photosystem (PS) 2 mediated oxygen evolution, and PS1 activities were also delayed to a greater extent. Absorbed excitation energy distribution was more in favour of PS1 in Al3+ plus kinetin-treated leaf thylakoids at 72 h.

Additional key words: aluminium; chlorophyll a fluorescence; electron transport; leaf senescence; photosystem
