Differential characteristics of photochemical acclimation to cold in two contrasting sweet sorghum hybrids por Zegada Lizarazu, Walter, Luna, Dario Fernando, Monti, Andrea

“…The higher cold tolerance of Bulldozer was partially related to a more efficient photochemical regulation mechanism of the incoming light energy: the higher tolerance of photosystem II (PSII) to photo‐inactivation was because of a more effective dissipation capacity of the excess of energy and to a more balanced diversion of the absorbed energy into alternative energy sinks. …”
