Title: The Induction of Salinity Stress Resistance in Rosemary as Influenced by Salicylic Acid and Jasmonic Acid
Abstract: This pot study was carried out as a factorial experiment. The foliar application of salicylic acid (SA) and jasmonic acid (JA) both, at three levels and salinity stress at four levels were applied. The results showed that salinity resulted in a significant loss of most morphological traits, protein, total chlorophyll, and catalase activity, whereas leaf proline content, superoxide dismutase activity, peroxidase and chlorophyll b significantly increased. The interaction of the three studied factors influenced protein content and plant weight significantly. Although salinity stress reduced these traits, SA application improved them. Also, SA application entailed the improvements in plant growth, proline, and antioxidant enzymes under salinity stress. Nonetheless, JA application had slight or insignificant impact on the traits. Thus, we can say that rosemary is relatively capable of coping with salinity. But, when the stress is intensified, even the resistance mechanism of the plant fails to counteract the severe stress.
