Abstract

Iodine (I) is considered an indispensable trace element for humans due to its capacity to promise a normal functions of thyroid hormones, preventing cretinism, goiter, reproductive failure, and diverse types of brain injury. Vegetable grafting is a technique for securing yield constancy and/or improving fruit quality. The study evaluated the combined effect of I-dosages and grafting onto Solanum torvum rootstock on ‘Birgah’ eggplant. Iodine at 100 or 300 mg L−1 enhanced marketable yield by 28.8% and 8.5%, respectively, compared with the control. Plants grafted onto S. torvum and self-grafted plants increased marketable yield by 53.0% and 45.8%, respectively compared with the ungrafted plants. I-biofortification determined a linear decrease in SSC as I-dosage increased. I-enrichment at 300 and 600 mg L−1 improved fruit dry matter and ascorbic acid compared with the control. The combinations of self-grafting × I-biofortification at 600 mg L−1 and ungrafting × I-biofortification at 600 mg L−1 improved total anthocyanins concentration by 8.5% and 9.1%, respectively, compared with the ungrafting × 0 I-biofortification combination. Exposing ungrafted plants to 600 mg I L−1 resulted in a significantly higher chlorogenic acid content compared to the control. Glycoalkaloids concentration in the fruits was always below the suggested safety value (200 mg 100 g−1 DW). Grafting enhanced proteins, K, Fe and Zn by 22.9%, 7.2%, 20.0% and 2.4%, respectively compared with ungrafting. I concentration in fruit of grafted plants varied from 0.67 mg kg−1 DW at 0 mg I L−1 to 188.67 mg kg−1 DW in plant biofortified with the highest I-dosage. The pulp browning potential was significantly dependent upon I-dosage and grafting with the lowest values found in fruits from grafted plants supplied with 0 or 100 mg I L−1. The present results suggested that I-biofortification at 300 or 600 mg L−1 and grafting, successfully boosted nutritional and functional traits of ‘Birgah’ eggplant, securing satisfactory yield and yield-related traits.
