From: Responses of growth and photosynthesis to alkaline stress in three willow species
Effects of alkaline stress on the morphology of three willow cuttings (a: S. matsudana; b: S. gordejevii; c: S. linearistipularis). Note: From left to right are the changes of willow cuttings growth with the increase of pH on the 8th day of stress.
