“…Proline is considered to be a source of carbon and nitrogen for rapid recovery from stress and growth, a stabilizer for membranes and some macromolecules and also a free radical scavenger [47]. Tuna et al, (2008) [50] also reported decrease in proline contents in wheat cultivars grown under salinity and silicon and suggested that there is a definite decreasing effect of Si on proline accumulation. However, proline is a plant osmoregulator under stress condition and may cause decrease in growth and dry matter accumulation in salt stress [51].…”

The effect of NaCl with or without silicon on the growth and metabolism in rice seedlings cv. MTU1010 was studied. In these seedlings, the oxidative stress has been observed with NaCl treatments and the levels of proline, H2O2 and malondialdehyde contents were increased whereas catalase activity was decreased. NaCl exposure at 25 mM, 50 mM and 100 mM concentrations in the test seedlings resulted in an increase in both reducing and non-reducing sugar content. There was a decrease in starch contents and the activity of starch phosphorylase was increased. NaCl stress also affected the activities of different carbohydrate metabolizing enzymes. The activities of sucrose synthase and sucrose phosphate synthase were increased, while the activity of acid invertase was decreased. Joint application of silicon with NaCl showed significant alterations on all parameters tested under the purview of NaCl treatment alone leading to better growth and metabolism in rice seedlings. Thus the use of silicon enriched fertilizers may help to grow healthy rice plants in NaCl rich soil.

“…Applying silicon to wheat improved photosynthetic activity. Tuna et al (2008) found that silicon increases chlorophyll pigments under normal and salinity stress conditions. Applying silicon to saline soils resulted in reducing the amount of Na + taken up by plants leading to maintaining photosynthesis process (Wang & Han, 2007).…”

T HE PRESENT study was carried out to investigate the effect of high NaCl concentrations on some growth parameters and physiological processes of wheat (Triticum aestivum L.) plant. The results indicated that Gemeza.9 was the most sensitive cultivar to high salinity levels compared to all tested wheat cultivars. Moreover, salinity stress caused a reduction in the germination percentage by 65% and all growth parameters by 21%, 25% and 60% in the lengths of shoot, root and leaf area, also by 27% and 48% in fresh weights of shoot, root and 40% and 75% in dry weights of shoot and root. It also increased the activity of antioxidant enzymes (peroxidase and catalase), lipid peroxidation and ascorbic acid content. Salinity induced increase of osmolytes compounds such as total soluble proteins, carbohydrates and amino acids. Furthermore, all measured yield parameters, the percentage of grain's maturity and productivity were highly decreased. Accordingly, the role of potassium humate and potassium silicate either sole or combined in alleviating the toxic effect of salinity was also studied. Results showed that application of potassium humate as sole had a stimulatory effect higher than potassium silicate or their combination. It increased the germinating percentage by 128% at 200mM NaCl. In addition, potassium humate and potassium silicate increased the photosynthetic activity, decreased the activity antioxidant enzymes (Peroxidase and Catalase) as well as biosynthesis of MDA and ascorbic acid also they induced increase biosynthesis of proteins and carbohydrates in yielded grains. Accordingly, our study recommends the application of potassium humate as an organic fertilizer and potassium silicate as a foliar spray for improving the quality and quantity of the sensitive wheat cultivar Gemeza.9 cultivated in salty lands and increases its productivity.

“…Romero-Aranda et al (2006) reported that Si alleviates the deleterious salt effects on tomato plant growth by improving plant water status. Tuna et al (2008) in a growth room experiment reported that supplementary Si at both 0.25 and 0.5 mM ameliorated the negative effects of salinity on wheat plant dry matter and chlorophyll content. Sodium concentration in plant tissues increased in both leaves and roots in the high NaCl treatment and Si treatments lowered significantly the concentrations of Na in both leaves and roots.…”

“…In addition to the impact of Si on plant protection, various other beneficial effects of Si, such as amelioration of the adverse effects of aluminium (Al) and manganese (Mn) toxicity to plants improvement of water use efficiency, as well as enhancement of salt tolerance (Liang et al 1996;Romero-Aranda et al 2006;Tuna et al 2008) have been reported. Epstein (1999) reported a possible effect of Si on plant water relations in the mitigation of salt damage by Si.…”

In order to study the effects of salinity and silicon application on root characteristics, growth, proline content, leaf and root ion accumulation of purslane (Portulaca oleracea L.), a greenhouse experiment was conducted at Ferdowsi University of Mashhad, Iran. The experiment was carried out in a split plot design in which levels of salinity (0, 120 and 240 mM) were allocated as main plots and silicon application of 1 mM sodium silicate and no application assigned as subplots with three replications. The results indicated that salinity caused a reduction in root growth (volume, area, diameter, total and main length and root dry weight), and shoot biomass accumulation. Both root and leaf sodium (Na) content and leaf proline content increased with increasing salinity. Leaf and root potassium (K) content decreased with increasing salinity. Application of silicon improved root area, root dry weight, and leaf and root K content in the presence of salinity. It also caused a significant reduction in leaf Na content and consequently improved the K/Na ratio in leaves. Based on these results, P. oleracea has the capacity to grow in salt stress conditions and could be considered as a medicinal and vegetable for growth in harsh environments.
