Abstract
Indole acetic acid (IAA) and salicylic acid (SA) are plant bioregulators that stimulate the desired growth and quality response in crops. This study examined the impacts of IAA or SA seed pre-treatment on phytochemical constituents and antioxidants potential in three genotypes of tomato plant. The results indicated that IAA and or SA treatments increased height of the three genotypes of tomato significantly (P ≤ 0.05) when compared with the control group. Lycopene, total flavonoid and phenolic contents of genotypes F2 cobra and panther 17 F1 treated with 40, 80, and 120 mg/L concentrations of IAA, respectively increased significantly as compared to the control group. Furthermore, IAA and or SA significantly increased H2O2 scavenging activity of F1 KIARA by 5.0% compared to the control (0.2%). Genotype F1 KIARA treated with IAA and or SA (80 and 120 mg/L) had a significant increase in DPPH scavenging activity by 55.0% and 53.0% respectively, relative to control group (11%). The Fe2+-chelating activity of IAA-treated (80 mg/L) F1 KIARA and F2 COBRA increased by 56.0% and 17.0%, respectively compared to the control. The synergistic effect of IAA and SA showed a significant effect on phytochemical constituents and antioxidant potential than individual treatment. The results showed that IAA application or in combination with SA could be used as an alternative bio-stimulant to improve the quality of tomato.
