Abstract

This article investigates how iron nutrition influences chilling-induced damage in cucumber (Cucumis sativus L.) leaves under abiotic stress. The study found that cucumbers grown under high-iron conditions experienced more severe chilling damage, particularly under light exposure, due to increased iron accumulation in shoots and enhanced lipid peroxidation linked to reactive oxygen species (ROS) toxicity. Conversely, low-iron conditions alleviated chilling damage and reduced oxidative stress markers. The research highlights that light-dependent iron translocation from roots to shoots exacerbates chilling injury by promoting iron-driven oxidative damage, emphasizing the importance of managing iron nutrition to improve chilling stress tolerance in cucumbers and potentially other crops.
