Replication data for: Is Discrimination of 13C in Potato Leaflets and Tubers an Appropriate Trait to Describe Genotype Responses to Restrictive and Well-Watered Conditions?

Greenhouse experiment to compare physiological performance and biomass accumulation among genotypes along the growing period and to test the reliability of 13C discrimination (∆) of leaflet and ∆tuber to determine key mechanisms responsible of the varietal differences in biomass accumulation and tuber yield under different water availability levels.
