Leaf C and N composition shedding light on easing drought stress through partial K substitution by Na in eucalyptus species.

This work aimed to investigate the partial K-replacement by Na supply to alleviate drought-induced stress in Eucalyptus species. Plant growth, leaf gas exchange parameters, water relations, oxidative stress (HO and MDA content), chlorophyll concentration, carbon (C) and nitrogen (N) isotopic leaf composition (δC and δN) were analyzed. Drought tolerant E.
