Résumé : | Radiative de-activation of excited chlorophyll was measured in leaves of different cereal varieties exposed to water stress using two in vivo chlorophyll fluorescence methods. We measured steady-state and modulated chlorophyll fluorescence. Our results demonstrate that both fluorescence technic can be used to readily monitor drought induced damages. Two indexes were defined: the (P-S)/S obtained from steady-state kinetics and the photochemical quenching derived from the modulated fluorescence. The differential susceptibility of our wheat and barley varieties suggest that both fluorescence methods can be useful in large screening protocols designed to breed tor drought tolerance. © 1990 Taylor and Francis Group, LLC. |
