“…Gu et al [53] mentioned that it has been observed that the relative electrical conductivity of various plant leaves tends to increase with higher salt concentrations. These findings are further supported by the research of Ghoname et al [17] and by the present study on M. azedarach. On the other hand, our study revealed that the application of EBR through spraying reduced the average relative electrical conductivity, indicating a potential mitigation of cell membrane damage induced by salt stress.…”

“…However, the application of exogenous EBR treatment was able to effectively restore the chlorophyll content depending on the EBR concentration. The finding aligns with previous research conducted on apple [21], snap bean [17] and soybean [18]. As a result, our study supports the notion that the application of foliar BR spraying has the potential to enhance chlorophyll content and promote increased photosynthetic capacity [19].…”

“…One of them, the application of brassinosteroids (BRs), has been found to have beneficial effects in supporting growth and alleviating the negative effects of salt stress [15]. It has been investigated in various plants [16], including mustard, eggplant, pepper, maize, black locust, common bean as well as snap bean [17], soybean [18], peanut [19], strawberry [20], apple [21], Atractylodes Macrocephala Koidz.

Salinity is a serious environmental problem following a worsening trend. This study investigates the role of 24-epibrassinolide(EBR) in regulating plant growth and physiological performances, particularly in alleviating the negative effects of salt stress. Melia azedarach L. seedlings from two seed sources, Sheyang (SY) and Xiashu (XS), were exposed to sea salt and treated with different concentrations of EBR within a 60-day period. The results demonstrate that appropriate EBR application improved the seedlings’ stress tolerance by promoting growth and physiological systems. In terms of the relative increment, it showed that a difference of 1.45% and 1.13% in the SY and XS groups was the positive effect of the highest EBR treatment concentration. As for diameter growth, the difference observed was 2.51% and 1.80% for the SY and XS groups, respectively. In all physiological measurements, including the content of photosynthetic pigments, water relations, membrane stability, osmolytes and antioxidant enzymes, significant changes generally observed between salt stress alone and the highest EBR treatment concentration. A better performance was observed in the SY seed source, which is of a coastal nature. These findings contribute to our understanding of Melia azedarach’s adaptation to changing environments and provide potential for further molecular studies as well as valuable insights for forestry, agricultural and ecological research.

“…The salinity-tolerant genotype showed higher enzyme activity, soluble sugar, and proline content, and lower osmotic potential and lipid peroxidation than the sensitive genotype [3]. This suggests that the tolerant genotype has a greater osmotic adjustment capacity [4], which enables it to absorb more water [5,6] while maintaining its enzymatic activity [7,8]. This is confirmed by the differences in the expression of the TaHKT1;5 gene (which codes for selective Na+ transport) in its leaves in favour of the salinity-sensitive genotype [3] and has been confirmed in recent studies [9,10].…”

“…Brassinolide (BR) is a kind of sterol hormone, which improves the plant growth and tolerance against different stresses (Yaqoob et al, 2022). Studies have shown that BR can alleviate and improve the saline-alkali induced growth inhibition (Ghoname et al, 2022). Photosynthetic characteristics and fluorescence parameters of Medicago sativa can enhance the stability of biofilm which can reduce malondialdehyde and H2O2 levels, and protect with chlorophyll (Ntoniou et al, 2017).…”

Salinity and alkali stresses are a major abiotic stress negatively affecting crop productivity around the globe. Therefore, it is mandatory to develop the effective measures to mitigate the adverse impacts of these stresses for ensuring sustainable crop productivity and food security. Therefore, a pot experiment determined the effects of brassinolide application, inoculation with AM fungi (Funneliformis mosseae) and their combined use on the growth, photosynthesis and antioxidant system of Leymus chinensis under saline-alkali stress (0, 150 mmol/L). The mechanism of the two to alleviate the saline-alkali stress of L. chinensis was explored. The physiological and biochemical indexes of Leymus chinensis were significantly affected under saline-alkali stress (150 mmol/L). Inoculation of AM fungi and application of brassinolide effectively increased the biomass accumulation in the upper part (∼ 25-40%) and root (15-35%) system of L. chinensis under saline-alkali stress. Further AMF also improved photosynthetic pigments (chlorophyll a, chlorophyll b), photosynthetic rate (Pn), Intercellular CO2 concentration (Ci), stomata conductance (Gs), transpiration rate (Tr), chlorophyll fluorescence antioxidant enzymes (SOD: superoxide dismutase. CAT: catalase APX: ascorbate peroxidase, GR: Glutathione reductase) activity, and decreased malondialdehyde (MDA: ∼ 40-50%) and hydrogen peroxide (H2O2: ∼ 30-40%) accumulation. Therefore, under saline-alkali stress conditions, the combination of brassinolide and AM fungi proved better to mitigate their toxic effects.
