1H NMR metabolic profiling dataset of spiny chicory (Cichorium spinosum L.) exposed to abiotic stresses.

The data presented here were derived by ¹H NMR metabolic profiling of stamnagathi (Cichorium spinosum L.) plants following treatments with different isosmotic salt solutions; eight saline nutrient solutions with two different levels of total molar concentrations, which were obtained by adding different amounts of NaCl, KCl, Na₂SO₄ or CaCl₂ to the replenishment nutrient solution, were applied. The ¹H NMR metabolite profiles of stamnagathi plants', which are included in this article, were recorded 56 days after transplanting. Since stamnagathi is a niche product combining unique taste and superior phytonutrient content (e.g. vitamins C and K1, lutein, β-carotene, tocopherols, phenolic acids, fatty acids, minerals, and glutathione), the dataset could serve as a reference for future metabolomics studies related to the investigation of the effects of the four salinity sources on the plant's metabolism. Also, the dataset could be a valuable resource for the discovery of validated biomarkers of the plant's tolerance to salinity stress and responses to new plant protection products (e.g. bioelicitors). The dataset support the research article "Salinity source alters mineral composition and metabolism of Cichorium spinosum" authored by Ntatsi et al., (2017) [1].
