Effect of 24 h cold priming at 4 °C on photosynthetic electron transport activity and regulation after cold (left) and light triggering (right). The means and standard deviations of the quantum yields of photosystem II (ΦPS-II), photochemical quenching (qP) and non-photochemical quenching (NPQ) as determined for each of the 4 biological replicates at an photosynthetic photon flux density of 185 μmol quanta m− 2 s− 1 in parallel in triggered (T) and primed + triggered plants (PT)
