It is known that salinity stress, one of the abiotic stress factors, significantly limits the germination, growth, development, and crop yield of plants. Therefore, this study was conducted to evaluate the effects of salinity (control, 50, 100 ve 150 mM) on seed germination and the effect of salicylic acid (control, 0.25, 0.50, 0.75 ve 1.00 mM) on seed germination to improve salt tolerance in cannabis seeds. The physiological characteristics of the plant, such as germination percentage, germination duration, germination index, radicle length, plumule length, wet radicle weight, dry radicle weight, wet plumule weight, and dry plumule weight, were analyzed. Depending on the salinity application dose, it was observed that there was a significant decrease in the germination parameters of cannabis seeds compared to the control. It was observed that salicylic acid treatments under salinity stress positively affected all the characters examined and reduced germination arrest due to increasing concentration levels. Although it is recommended to prepare seeds with 0.5 mM salicylic acid pre-application dose against salt stress of the cannabis plant,it is essential to expand the studies on its transfer to practice. As a result, salicylic acid will provide positive results that can be transferred to practice by increasing the resistance of cannabis plants against salinity, especially in agricultural soils with salt problems, as it will be more sensitive to pests and diseases.

Seckin-Dinler, Burcu; Tasci, Eda; Sarisoy, Ufkun; Gul, Volkan
Methyl jasmonate (MeJA), a methyl ester of jasmonic acid, is a naturally produced phytohormone that regulates plant growth and development by maintaining the morphologic, physiological, and biochemical development of plants. The purpose of this study was to determine the effect of methyl jasmonate and endogenous salicylic acid on the stimulation and scavenging of reactive oxygen species (ROS) under salt stress in soybean roots and leaves. Soybean leaves were sprayed with 0.5 mu M methyl jasmonate for 4 days, followed by exposure to 200 mM NaCl. Foliar application of MeJA did not change the leaf area; however, it increased the relative water content (RWC), chlorophyll content, relative electrolyte leakage (REL), and root and shoot fresh weight, and it lessened the stress-induced oxidative damage by decreasing the levels of hydrogen peroxide (H2O2), malondialdehyde (MDA). Curiously, catalase (CAT) enzyme and isoenzyme activity, and also endogenous salicylic acid (SA) were decreased by MeJA treatment. As a result, this study firstly determined that MeJA treatment improved the soybean performance under salinity by acting role as an antioxidant and cooperating with SA.

The time-dependent effect of salicylic acid (SA) on alleviating cold damage in the Tokak (tolerant) and Akhisar (sensitive) varieties of barley (Hordeum vulgare) was investigated. Seedlings subjected to 0.0, 0.1, and 1 mM SA for 7 days were transferred to cold (7/5 °C) on days 7, 14, 21, and 28 for 3 days. It was found that 0.1 mM SA had a greater alleviating effect, decreasing the freezing injury in both varieties for at least 10 days after the application. Moreover, 0.1 mM SA had a greater effect on alleviation in Tokak by increasing the ice nucleation activity of apoplastic proteins extracted from the leaves. SA was effective for at least 24 days in decreasing the effect of freezing temperature by regulating apoplastic proteins in the leaves after the application. Furthermore, 0.1 and 1 mM SA had an alleviating effect by decreasing the lipid peroxidation level in both varieties for at least 24 days after the application. It can be seen that SA treatment can play a positive role in alleviating cold damage in barley. Therefore, it is suggested that results from SA treatments may contribute to research related to diminishing cold damage in agricultural applications.
