“…Our observations are in accordance with the conclusions of Agamy et al, (2013) in tomato. Naureen & Naqvi (2010) reported that increased carbohydrate levels under salt stress could be suitable parameters for identifying salt-tolerant wheat plants. This increase in total carbohydrate levels is a mechanism of osmoregulation ( Siringam et al, 2012;Shaddad et al, 1990), and is involved in protecting plants from oxidative stress and maintaining the structures of proteins and membranes as well (Hajihashemi et al, 2006).…”

A study was conducted to evaluate the role of salicylic acid (SA; 0, 0.5 and 0.75 mM) on the growth and activity of antioxidant enzymes and biochemical attributes in wheat (Triticum aestivum L.cv. Sods 1) under salinity stress. Salinity exposure (0, 25, 75 and 125 mM NaCl) reduced growth of wheat significantly by reducing the fresh and dry weight of shoot and root, leaf development and inducing necrosis on old leaves. Lipid peroxidation and production of hydrogen peroxide (H2O2) increased by 3.37 fold and 2.54 fold, respectively, while membrane stability declined with 125 mM NaCl concentration which were however, ameliorated by the application of SA. Under normal conditions, application of SA (0.5 mM) improved growth significantly compared to the untreated controls. Salinity (125 mM) stress enhanced the accumulation of proline (4.63 fold), carbohydrates (39.61%), free amino acids (9.44) and protein content (7.91%) which were further stimulated by application of SA leading to better stress adaptation. Application of SA to salinity stressed upregulated the activity of antioxidant enzymes like SOD, CAT and APX by 1.76 fold, 2.25 fold and 2.22 fold, respectively leading to better elimination of reactive oxygen species and protection against oxidative stress. Moreover, excess uptake of Na in salinity stressed plants reduced the uptake of K + and initiated leaf necrosis. However, application of SA mitigated these negative effects to considerable extent. In conclusion, salinity stress adversely affected the growth and development of wheat plants. However, supplementation of proper dosage of SA mitigated these negative effects of salinity through the modulation of the levels of osmolytes, activities of antioxidant enzymes and uptake of essential elements.

“…Thus, the up-regulation of photosynthetic pigments in broad bean could increase the efficiently of photosynthetic apparatus in broad bean which leads to increasing the food manufacturing (carbohydrates and proteins) in broad bean than in wheat. Other investigators, [38] reported that, the increased carbohydrate contents under salt stress could be good parameter to identify salttolerant wheat plants. This increasing in the total carbohydrate contents act as osmoregulation mechanism [39,40] and also it used to protect the plants from oxidative stress and maintain the protein and membrane structure [41].…”

Broad bean and wheat plants responded differently to salinity stress. The reduction in the dry weight of shoot of about 65% in wheat (cv. Giza 168) and about 35 % in broad bean (cv. Sakha 1) was associated with the more stability of photosynthetic pigment in broad bean than in wheat. At 150 mM of NaCl, carbohydrates and proteins accumulation in broad bean was evident than in wheat and this was accompanied by accumulation of sufficient amount of Ca 2+ ions in broad been and Na + ions in the shoot and root of wheat. Consequently, lipid peroxides (MDA) content was higher in wheat compared to broad bean plants. The Na + uptake at the root surface was higher in broad bean than in wheat. However, broad bean showed lowest Na + translocation from root to shoot. The observable increase in the activity of catalase and proline content in broad bean more than in wheat could play the pivotal role in the detoxification of free radicals.

“…However, V. luteola and T44 (relatively tolerant) retained higher content of nonreducing sugar content than PB (relatively susceptible). However Naureen and Naqvi (2010) reported that salinity stress of 200 mM significantly increased the amount of nonreducing sugar in wheat.…”

The present investigation was conducted in Department of Botany and Plant Physiology, CCS Haryana Agricultural University, Hisar during 2014−15 and 2015−16. Waterlogging and salinity are most severe stress all around the world. When water and salt is present in excess amount than its optimum requirement it refers to waterlogging and salinity respectively. Waterlogging when combined with salinity exaberate the effect of salinity. Four pigeonpea genotypes (ICPH-2431, PARAS, UPAS-120, H09-33) were raised in polythene bags filled with half kg soil+FYM manure mixture and Carbohydrate metabolism and aerenchyma formation under twelve days waterlogging, salinity and combined stress was studied in roots of 20 and 40 day old pigeonpea plants 1, 4 and 8 days after removal from treatment under pot house conditions. Decline in total and nonreducing sugar content and a significant increase in reducing sugar content, sucrose synthase activity and alcohol dehydrogenase activity was observed with waterlogging and salinity stress. No survival was observed under combined waterlogging and salinity treatment in any genotypes. Waterlogging was found more deleterious compared to alone salinity treatment. Aerenchyma formation was observed only under waterlogging treatment. Both the stresses are found more deleterious when given at later stages of growth. ICPH performed best among all the genotypes followed by PARAS, HO9-33 and UPAS-120 in terms of total sugar, nonreducing sugar, reducing sugar, sucrose synthase activity, alcohol dehydrogenase activity and aerenchyma formation. The combined effects of salinity and waterlogging are common in saline areas, particularly where shallow salinewater tables exist or where soils are also sodic, reducing
