“…The Pn, Tr, RH-S, gs, Ci, were dropped to different salt stress levels. The decline of photosynthesis activities of salt-tolerant cultivars was less than salt sensitive cultivars (Akram and Ashraf, 2013). The current results showed that these characteristics affected less in LYP9 as compared to NPBA due to its susceptibility to salt stress.…”

“…This difference is directly linked with chlorophyll contents (SPAD values), and photosynthesis activities in rice leaves. The results in a reduction of the C assimilation and biomass production due to osmotic stress and ion imbalance high Na + and Cl -in soil and plant tissues under alt stress (Akram and Ashraf, 2013). From the results of all parameters, we categorized both cultivars against salt stress.…”

The salt stress affects plant growth and physiological characteristics during early growth stages in rice (Oryza sativa L.) The objective of this study was to examine the influence of salt stress on rice growth during early stages and to find out their salt tolerance levels. A pot culture experiment was conducted in rice cropping season 2016, with completely randomized design (CRD) and three replicates. The treatments were two rice cultivars, 'Liangyoupeijiu' (LYP9) and 'Nipponbare' (NPBA) with four salt stress levels 0 (control, CK), 1.5 (low salt stress, LS), 4.5 (medium salt stress, MS), and 7.5 g (heavy salt stress, HS) NaCl kg -1 soil at different growth stages with six seedlings per pot. About 15 parameters were recorded and most of the treatments were significantly different (P ≤ 0.05) from each other. The results showed that salt stress reduced seed emergence characteristics of the rice. It also decreased photosynthetic parameters, growth characteristics including DM, and seedling height reduction increased at early seedling and maximum tillering stage in both rice cultivars but this disaster is less in 'LYP9' than 'NPBA'. On the basis of DM reduction, 'LYP9' was categorized as moderately susceptible (MS) and susceptible (S) at HS during early growth stage, and 'NPBA' was categorized as sensitive to the HS stress level. The result suggested that 'LYP9' showed somehow resistance under salt stress than 'NPBA'. This study will help us to provide new ideas for improving the high yielding rice cultivar (LYP9) to salt tolerance by genetic modification and cultivation techniques.

“…It preserves adequate redox reactions in chloroplasts and stabilizes thylakoid functions and membrane structure during plant development under stress (Munne-Bosch, 2005). Chlorophyll content is often linked to visual symptoms of plant and photosynthetic activity (Akram and Ashraf, 2013). In the current study, under water-deficit conditions, chlorophyll pigments decreased significantly under water stress.…”

Alpha-tocopherol (α-Toc), so-called vitamin E, is a low molecular weight lipophilic antioxidant that generally protects plants from stress-induced cellular oxidation. It is well known that exogenously applied α-Toc is effective in improving plant growth and developmental processes under adverse environmental conditions. The current study was performed to determine the best concentration of α-Toc [0 (no spray), 100, 200, and 300 mg L -1 ] that could improve the biological yield and chemical constituents of fresh green pods of mung bean (Vigna radiata) and hence their quality under varying water regimes. Foliar spray of α-Toc significantly improved total soluble proteins, chlorophyll a and b, total soluble sugars, proline, phenolics, total free amino acids, nonreducing sugars, and activities of SOD, POD, and CAT under water stress conditions. However, no prominent change was observed in reducing sugars and biological yield due to externally applied α-Toc in either mung bean cultivar subjected to either water regime. Both mung bean cultivars (Cyclone 7008 and Cyclone 8009) showed similar behavior in chlorophyll a and b, while cv. Cyclone 7008 was superior with respect to the concentrations of total soluble sugars and total free amino acids, whereas Cyclone 8009 was better in activities of CAT, SOD, and POD. Overall, externally applied 200 and 300 mg L -1 α-Toc considerably enhanced the activities of antioxidant enzymes (SOD, POD and CAT), chlorophyll a and b, proline, and total phenolic contents in both mung bean cultivars.

“…Although this approach has gained considerable ground worldwide, there are still many challenges in attaining the desired outcome that need to be resolved. Alternatively, a shotgun approach has been adopted by many researchers (Ashraf and Foolad, 2005;Tanou et al, 2012;Akram and Ashraf, 2013). This approach is an immediate remedy to improve plant growth development under stress or nonstressed conditions by exogenously applied macro-/micronutrients, plant growth regulators/ hormones, osmoprotectants, and antioxidants (Ashraf andFoolad, 2005, 2007;Ali et al, 2008;Akram and Ashraf, 2013).…”
