Abstract

Human iodine (I) shortage disorders are documented as an imperative world-wide healthissue for a great number of people. The World Health Organization (WHO) recommends I consumptionthrough ingestion of seafood and biofortified food such as vegetables. The current workwas carried out to appraise the effects of different I concentrations (0, 50, 250, and 500 mg L-1),supplied via foliar spray on curly endive grown in the fall or spring–summer season. Head freshweight, stem diameter, head height, and soluble solid content (SSC) were negatively correlated to Idosage. The highest head dry matter content was recorded in plants supplied with 250 mg I L-1,both in the fall and spring–summer season, and in those cultivated in the fall season and suppliedwith 50 mg I L-1. The highest ascorbic acid concentration was recorded in plants cultivated in thespring–summer season and biofortified with the highest I dosage. The highest fructose and glucoseconcentrations in leaf tissues were obtained in plants cultivated in the spring–summer season andtreated with 250 mg I L-1. Plants sprayed with 250 mg I L-1 and cultivated in the fall season hadthe highest I leaf concentration. Overall, our results evidently suggested that an I application of250 mg L-1 in both growing seasons effectively enhanced plant quality and functional parameters incurly endive plants.
