Foliar application of abscisic acid mitigates cadmium stress and increases food safety of cadmium-sensitive lettuce (Lactuca sativa L.) genotype.

ABSTRACT: Cadmium (Cd^2 +) is among the toxic non-essential heavy metals that adversely affect plants metabolic processes and the safety of produce. However, plant hormones can improve plant's tolerance to various stresses. This study investigated the effect of exogenous abscisic acid (ABA) on the biochemical and physiological processes and food safety of cadmium (Cd^2 +)-sensitive lettuce genotype (Lüsu). Seedlings were subjected to five treatments: [(i) Control (untreated plants), (ii) 100 µM CdCl₂, (iii) 100 µM CdCl₂+10 µg L^-1 ABA (iv) 10 µg L^-1 ABA, and (v) 0.01 g L^-1 ABA-inhibitor (fluridone)] for fourteen days in hydroponic system. The 100 µM CdCl₂ increased the contents of hydrogen peroxide (H_2</
