“…Likewise, Mäkelä et al (2000) also found an increase in Chl content in tomato plants under drought or salinity by means of foliar application of GB. Although other reports indicated that the GBinduced alleviation of Chl content decline was attributed to enhanced activity of the Chl-degrading enzyme chlorophyllase (Mishra and Sharma, 1994), increased cytokinin concentration, which retards Chl degradation (Shetty et al, 1992), decreased toxic ion, especially sodium concentration, increased some ions as Mg 2+ , is which needed for Chl synthesis, and increased potassium concentration (Shaddad et al, 1999).…”

Salinity stress may involve the accumulation of glycine betaine (GB). The objective of this study was to examine whether exogenous GB would ameliorate the detrimental effect of salinity stress on perennial ryegrass (Lolium perenne). The grass was subjected to two salinity levels (0 and 250 mm NaCl) and three GB levels (0, 20, and 50 mm). Salinity resulted in a remarkable decrease in vertical shoot growth rate (VSGR), shoot and root fresh weight, relative water content (RWC), relative transpiration rate (Tr), and chlorophyll (Chl) content, superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) activities. Plants subjected to salt exhibited an increase in leaf electrolyte leakage (EL), lipid peroxidation (MDA), and proline content. Application of GB reduced EL, MDA, and proline content in salt-stressed plants. Perennial ryegrass subjected to salt stress plus GB had a greater level of VSGR, RWC, relative Tr, Chl content, and activities of SOD, CAT, and APX when compared with salt-stressed without GB. Salt stress increased Na+ and decreased K+ content, which resulted in a higher Na+/K+ ratio in perennial ryegrass. Application of 20 mm GB suppressed Na+ accumulation, whereas the K+ content was significantly increased in shoot, which led to a higher K+/Na+ ratio under saline conditions. These results suggested that GB-enhanced salt tolerance in perennial ryegrass was mainly related to the elevated SOD, CAT, and APX activity and alleviation of cell membrane damage by reducing oxidation of membrane lipid and improving the ion homeostasis under salt stress.

“…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.

“…The adverse effect of salinity on plants may lead to disturbances in plant metabolism, which consequently lead to a reduction of the plant growth and productivity (Greenway and Munns 1980;Sharma and Hall 1991). The strategy of osmotic adjustment varied from plant to another as well as tissues (Shaddad et al 1990). Many trials have been made to help the plants to overcome these disturbances using various treatments in the laboratory, for future application in the field.…”

Effect of grain soaking presowing in 1 mM salicylic acid (SA) and NaCl (0, 50, 100, 150 and 200 mM) on barley (Hordeum vulgare cv Gerbel) was studied. Increasing of NaCl level reduced the germination percentage, the growth parameters (fresh and dry weight), potassium, calcium, phosphorus and insoluble sugars content in both shoots and roots of 15-day old seedlings. Leaf relative water content (RWC) and the photosynthetic pigments (Chl a, b and carotenoids) contents also decreased with increasing NaCl concentration. On the other hand, Na, soluble sugars, soluble proteins, free amino acids including proline content and lipid peroxidation level and peroxidase activity were increased in the two plant organs with increasing of NaCl level. Electrolyte leakage from plant leaves was found to increase with salinity level. SApretreatment increased the RWC, fresh and dry weights, water, photosynthetic pigments, insolube saccharides, phosphorus content and peroxidase activity in the stressed seedlings. On the contrary, Na + , soluble proteins content, lipid peroxidation level, electrolyte leakage were markedly reduced under salt stress with SA than without. Under stress conditions, SA-pretreated plants exhibited less Ca 2+ and more accumulation of K + , and soluble sugars in roots at the expense of these contents in the plant shoots. Exogenous application (Grain soaking presowing) of SA appeared to induce preadaptive response to salt stress leading to promoting protective reactions to the photosynthetic pigments and maintain the membranes integrity in barley plants, which reflected in improving the plant growth.
