Chromium (Cr) is a heavy metal that poses a significant threat to both the environment and human health. The accumulation of Cr in soil can adversely affect the growth and development of plants. In this study, it was aimed to investigate the morphological changes induced by Cr stress in rapeseed plants (Brassica napus L.) and the potential of salicylic acid (SA) as a mitigation strategy. Hydroponically grown rapeseed plants were exposed to different concentrations of Cr (1, 2, 3, 4 and 5µM) and treated with or without SA (0.25 µM). The results showed that Cr stress significantly reduced plant growth and development, as evidenced by reduced germination potential, root and shoot length, area of leaf, fresh and dry weight. The application of SA mitigated the adverse effects of Cr stress to some extent. The SA-treated plants showed a significant increase in plant growth due to decrease in chromium uptake. These results indicate that SA has the potential to mitigate the adverse effects of Cr stress on plant growth and development. In conclusion, our study provides insights into the morphological changes induced by Cr toxicity in rapeseed plants and highlights the potential of SA as a mitigation strategy. Further research is needed to elucidate the mechanism by which SA mitigates Cr stress and to optimize the concentration and application of SA for maximum efficacy in the field.
