“…The increase in leave relative water content and decreased EC in cultivar CCMC under HBL spraying interval after 15 days in combination with AMF can be attributed to the improved water absorption from roots as AMF, on the one hand, have been reported to enhance root hydrolytic activity, cause osmotic balance, and improve nutrient absorption and composition of carbohydrates (Evelin, Kapoor, & Giri, 2009). HBL, on the other hand, regulates cell division, differentiation, and elongation along with enhanced proton pump efficiency to overcome toxic effects caused by Na + ion (Ali et al., 2008). The higher RLWC and lower EC from leaves might be due to the increased uptake of water, which detoxifies Na + ion concentration and results in higher photosynthetic activity and enhanced water absorption (Porcel et al., 2012).…”

“…Exogenously applied BRs reduces stress conditions by decreasing sodium uptake, EC, and lipid peroxidation. The foliar application of BRs under salt stress increased growth (Ahmad et al., 2017), photosynthesis, nutrient acquisition, mitotic index, and antioxidant enzymes (Ali et al., 2008; Fariduddin et al., 2014). Plants treated with BRs showed significant increment in gas exchange parameters, chlorophyll content, and leaf relative water content (Fariduddin et al., 2014).…”

Salinity is one of the major obstacles in the agriculture industry causing huge losses in productivity. Several strategies such as plant growth regulators with arbuscular mycorrhizal fungi (AMF) have been used to decrease the negative effects of salt stress. In our experiment, 28‐homobrassinolide (HBL) with spraying intervals was combined with AMF (Glomus versiforme) in cucumber cultivars Jinyou 1# (salt sensitive) and (Changchun mici, in short, CCMC, salt tolerant) under NaCl (100 mmol/L). Studies have documented that the foliar application of HBL and AMF colonization can enhance tolerance to plants under stress conditions. However, the mechanism of the HBL spraying intervals after 15 and 30 days in combination with AMF in cucumber under salt stress is still unknown. Our results revealed that the HBL spraying interval after 15 days in combination with AMF resulted in improved growth, photosynthesis, and decreased sodium toxicity under NaCl. Moreover, the antioxidant enzymes SOD (superoxide dismutase; EC 1.15.1.1) and POD activity (peroxidase; EC 1.11.1.7) showed a gradual increase after every 10 days, while the CAT (catalase; EC 1.11.1.6) increased after 30 days of salt treatments in both cultivars. This research suggests that the enhanced tolerance to salinity was mainly related to elevated levels of antioxidant enzymes and lower uptake of Na+, which lowers the risk of ion toxicity and decreases cell membrane damage.

“…Accumulation of proline under stress conditions is used as an adaptive mechanism by many plant species (CHU et al 1974, FRAN-CISCO et al 2007, ALI et al 2008, HASAN et al 2008, BAKHT et al 2012, BAKHT et al 2013, HAYAT et al 2013.

-One of the major issues with brassica oil seed production is the water requirement of the brassica crop. To address the problem, fi eld experiments were conducted to evaluate the effect of potassium (K) and water defi ciency levels on canola (Brassica napus L.). Analysis of the data revealed that application of K, irrigation and interactions between irrigation and cultivar (I × C), irrigation and potassium (I × K), potassium and cultivar (K × C), and irrigation and cultivar and potassium (I × C × K) had a signifi cant (p < 0.05) effect on shoot proline content, relative water content, plant fresh weight and grain yield. Potassium application, irrigation and interaction between I × C, K × C, and I × C × K had a signifi cant (p < 0.05) effect on shoot sugar content. Water defi ciency increased shoot proline and sugar contents and decreased relative water content. Potassium application increased shoot proline level in a dose dependent manner. Minimum proline and sugar contents and maximum relative water content, plant fresh and dry weight and yield were obtained when 100% irrigation was applied. Maximum grain yield was obtained upon application of 100% irrigation in combination with 120 kg ha -1 K.

“…However, the increase in RGR was attributed to the increase in the physiological growth parameter (NAR) rather than the morphological growth parameter (LAR).Thus suggests that EBL-induced salt tolerance in watermelon plant. Since salinity inhibits plant growth by adversely affecting various physiological and biochemical processes including photosynthesis, antioxidant capacity, and ion homeostasis, it is suggested that BRs enhanced growth of salt stressed plants might have been due to BRs-induced changes in these physiological or biochemical processes [6,13,14,15] . For example, Ali [14] reported that EBL increased growth in Indian mustard plants could be related to enhanced activity of antioxidative enzymes and proline level that protect the plants from oxidative damage.…”

Keywords: 24-epibrassinolide, watermelon, salt stress, relative growth rate, gas exchange. Abstract. The present study investigates the role of 24-epibrassinolide (EBL) in inducing plant tolerance to salinity. Seedlings of watermelon (Citrullus lanatus L.) were grown in the presence of 70 mM NaCl and were sprayed with 10 -6 M EBL at 7 days after transplantation and were sampled at 28 day. The plants exposed to NaCl exhibited a significant decline in relative growth rate, net CO2 assimilation, stomatal conductance, transpiration and water use efficiency. However, the follow up treatment with EBL significantly improved the above parameters. EBL treated plants had greater relative growth rate compared to untreated plants when exposed to salt stress. Application of EBL increased photosynthesis by increasing stomatal conductance in both control and salt stressed plants and may have contributed to the enhanced growth. The water use efficiency was improved because CO2 assimilation is more important than the transpiration.
