Coordination between water source partitioning and isohydric-anisohydric behavior shapes contrasting water use strategies of Tamarix chinensis and Ulmus pumila in saline-alkaline soils
Analysis identifies plastic water uptake in Tamarix chinensis and conservative strategies in Ulmus pumila, suggesting improved drought tolerance management.
Key Points
Anisohydric behavior in Tamarix chinensis results in better adaptability to variable precipitation, contributing to its drought tolerance.
Physiological characteristics were assessed, including stomatal conductance, predawn and midday leaf water potential during seasonal aridity.
Analysis employed δ 18 O stable isotopes alongside a MixSIAR model to investigate water uptake patterns in saline-alkaline environments.
These findings emphasize the importance of species selection and management for enhancing drought resilience in coastal plantations.
