From: Responses of growth and photosynthesis to alkaline stress in three willow species
Effects of alkaline stress on the quantum ratio of heat dissipation φDo (a: S. matsudana; b: S. gordejevii; c: S. linearistipularis), the quantum efficiency of electron transfer from electron acceptors φEo (d: S. matsudana; e: S. gordejevii; f: S. linearistipularis), the maximal photochemical efficiency of PS II φPo (g: S. matsudana; h: S. gordejevii; i: S. linearistipularis), and the ratio of transferred electrons to trapped electrons φDo (j: S. matsudana; k: S. gordejevii; l: S. linearistipularis) of three willow cuttings.
