Abstract: (21 Views)
In order to investigate the effect of seed priming with vitamin U on germination indices and antioxidant enzyme activity of French Bean under salt stress, a factorial experiment was conducted in a completely randomized design with three replications in the Agronomy Laboratory of the Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardabili in 2024. The treatments included four levels of salinity (0, 50, 100, 150 mM) and three levels of vitamin U (0, 2, 4 mM). The results showed that salinity stress reduced Germination Rate (GR). But priming with different levels vitamin U, especially the 4 mM level, improved these traits. The highest mean germination time was observed at 150 mM salinity. The activities of catalase, peroxidase, and superoxide dismutase enzymes in the application of vitamin U 4 mM and the control showed a decrease of about 59%, 46%, and 49%, respectively, compared to hydropriming and 150 mM salinity. Also, the alpha-amylase enzyme activity in priming with vitamin U 4 mM compared to the the control (distilled water) showed an increase of about 13%. The results of this research showed that french bean seed priming with vitamin U at a concentration of 4 mM is the most effective method to improve the germination of seedlings, and reduce the harmful effects of salinity on some traits in french bean seedlings and improve seedling growth by stimulating antioxidant enzymes.
