“…Similarly, Meneguzzo et al (1999) observed a greater increase in APX activity in a salt-sensitive cultivar than in a salt-tolerant one of wheat when exposed to NaCl stress. With the increase in salt stress, APX activity also increased in wheat (Heidari and Mesri 2008), cotton (Desingh and Kanagaraj 2007), stevia (Omran et al, 2021) and sea rocket (Amor et al, 2007) suggesting that high level of APX and salt-induced increase in APX activity could impart tolerance by detoxifying H 2 O 2 generated upon exposure of plants to saline conditions.…”

Summary Salinity is one of the most imperative global problems that affect crop productivity on a large scale. Salinity impairs plant growth and development by imposing various stresses. Therefore it is vital to decode those stress factors and identify possible solutions to improve agriculture productivity. However, the adaptive mechanisms under saline conditions of glycophytes have not been studied. The present study was undertaken to determine the effects of exogenous abscisic acid (ABA) on salinity tolerance in cotton plants. Some patterns of resistance development were revealed on the seedlings of two cotton cultivars, a salt-tolerant (Gulistan) and a salt-sensitive one (C-4727). Moreover, the antioxidant potentials of these cultivars were compared. The activities of ascorbate peroxidase (APX), super-oxide dismutase (SOD), as well as the quantity of endogenous ABA, malondialdehyde (MDA), and free proline (Pro) were determined in control and post treatment. Our results demonstrate significant differences between the salt- tolerant and sensitive cotton seedlings in response to saline stress, i.e., high levels of Pro and endogenous ABA, but lower MDA concentrations, and higher activity of APX and SOD for the salt-tolerant cultivar, Gulistan, as compared to the salt stress-sensitive cultivar C-4727.

“…It is well known that an increase in MDA content is considered an indicator of cellular oxidative damage that is caused by several environmental stress conditions [ 49 ]. Plants can defend themselves against various environmental stresses, including WL, by upregulating cellular proline levels and lowering the MDA production to maintain cell membrane stability, detoxifying reactive oxygen species (ROS) [ 50 ], and maintaining osmotic pressure [ 51 , 52 , 53 ]. In the present study, the proline and MDA levels were significantly raised with the increasing WL duration ( Figure 3 A,B).…”

The reproductive stage of cotton (Gossypium sp.) is highly sensitive to waterlogging. The identification of potential elite upland cotton (Gossypium hirsutum) cultivar(s) having higher waterlogging tolerance is crucial to expanding cotton cultivation in the low-lying areas. The present study was designed to investigate the effect of waterlogging on the reproductive development of four elite upland cotton cultivars, namely, Rupali-1, CB-12, CB-13, and DM-3, against four waterlogging durations (e.g., 0, 3, 6, and 9-day). Waterlogging stress significantly impacted morpho-physiological, biochemical, and yield attributes of cotton. Two cotton cultivars, e.g., CB-12 and Rupali-1, showed the lowest reduction in plant height (6 and 9%, respectively) and boll weight (8 and 5%, respectively) at the highest waterlogging duration of 9 days. Physiological and biochemical data revealed that higher leaf chlorophyll, proline, and relative water contents, and lower malondialdehyde contents, particularly in CB-12 and Rupali-1, were positively correlated with yield. Notably, CB-12 and Rupali-1 had higher seed cotton weight (90.34 and 83.10 g, respectively), lint weight (40.12 and 39.32 g, respectively), and seed weight (49.47 and 43.78 g, respectively) per plant than CB-13 and DM-3 in response to the highest duration of waterlogging of 9 days. Moreover, extensive multivariate analyses like Spearman correlation and the principle component analysis revealed that CB-12 and Rupali-1 had greater coefficients in yield and physiological attributes at 9-day waterlogging, whereas CB-13 and DM-3 were sensitive cultivars in response to the same levels of waterlogging. Thus, CB-12 and Rupali-1 might be well adapted to the low-lying waterlogging-prone areas for high and sustained yield.

“…Osmotic stress disrupts the normal cellular activities. Proline accumulation maintains osmotic pressure in plant cell playing a significant role in the protection of cell structure in many crops [41] . The accumulation of proline in brinjal genotypes were considerably influenced by different salinity levels [29] .…”

Salinity is one of the most brutal environmental stresses that delays seed germination, limiting plant growth and has an adverse effect on many important physiological processes of plants. This experiment was conducted to determine the effect of different salinity levels on the growth and chemical constituents of the brinjal (variety: Ventura) plant (Solanum melongena L.) during the period of February to August 2022 using the Completely Randomized Design (CRD) with three replications. Experimental results showed that percent germination, seedling and growth of brinjal plants were suppressed with increasing salt concentration under laboratory conditions at 0, 3, 6, 9 and 12 dSm -1 salinity levels. The best germination percentage (100%) was at the salinity level (0 dSm -1 ) and the lowest germination percentage (86.67%) was recorded at the highest salinity level (12 dSm -1 ). Plant height, root and shoot length, fresh and dry weight of brinjal plants were decreased with increasing salt concentrations. Chlorophyll, proline, protein and carotene contents of plants were largely affected by different salinity levels. Significant changes in the concentrations of mineral elements in brinjal plants were also observed with increasing salinity. The concentration of Na + in brinjal plants significantly increased with increasing the salinity levels. The highest Na + content (135 mg/100g) was recorded at 12 dSm -1 and the lowest (98.04 mg/100g) was at 0 dSm -1 . On Salinity effect…Mst. Nasrin Zahan et al.
