Melatonin (MT) can effectively resist multiple abiotic stresses, improving plant stress resistance. To analyze the mechanism of exogenous MT to enhance salt tolerance in red clover, we conducted a comprehensive study to examine the influence of exogenous MT on various parameters, including seed germination indices, seedling morphological traits, and physiological and photosynthetic indicators, using four distinct red clover varieties (H1, H2, H3, and H4). This investigation was performed under various salt stress conditions with differing pH values, specifically utilizing NaCl, Na₂SO₄, NaHCO₃, and Na₂CO₃ as the salt strePlants (Basel, Switzerland)2527https://www.ebi.ac.uk/biostudies/studies/S-EPMC11397702biostudies-literatureThe Physiological Mechanism of Exogenous Melatonin on Improving Seed Germination and the Seedling Growth of Red Clover (<i>Trifolium pretense</i> L.) under Salt Stress.PMC11397702Hong YLian YWang TLu ZYan DLiu RLi RYuan XWang YWang JfalseThe Physiological Mechanism of Exogenous Melatonin on Improving Seed Germination and the Seedling Growth of Red Clover (<i>Trifolium pretense</i> L.) under Salt Stress.Salt stress can affect various physiological processes in plants, ultimately hindering their growth and development.
