Abstract: (154 Views)
Salinity is one of the most important obstacles to plant growth in the world, affecting plant performance in various ways. Therefore, research and investigation of methods that can control and reduce the effects of salinity on plants is important. The present experiment was conducted as a factorial experiment in a completely randomized design with three replications on the Rosmarinus officinalis L. The first factor was sodium chloride treatment at five levels (0, 25, 50, 75, and 100 mM), and the second factor was allantoin treatment at three levels (0, 0.1, and 100 mM). The effects of these treatments on some growth indices, photosynthetic pigments, anthocyanin, proline, total phenolic content, and antioxidant activity of rosemary were investigated. The results showed that increasing salinity significantly reduced fresh and dry weights of roots and aerial parts as well as chlorophyll a and b contents; however, application of allantoin moderated the decreasing trend of these traits. With increasing salt concentration, anthocyanin, proline, and total phenolic contents increased significantly. Allantoin application significantly increased total phenolic content compared with the control and treatments without allantoin, while it had no significant effect on proline content. The results also indicated that antioxidant activity increased significantly under salinity stress and with allantoin application, and the interaction treatment of sodium chloride with allantoin exhibited the highest antioxidant capacity. Overall, the results of this study showed that although salinity had negative effects on some growth indices of rosemary, the application of allantoin was able to reduce these effects to some extent. On the other hand, levels of salinity and foliar application of allantoin significantly increased some secondary metabolites, including carotenoids, anthocyanins, total phenols, and antioxidant capacity, which seems to improve and enhance the medicinal properties of rosemary.
