“…Additionally, we observed that Si can regulate wound-related stress to plants by increasing the activities of antioxidant enzymes and decreasing the level of lipid peroxidation compared to non-Sitreated plants. These results further strengthen the role of Si as an efficient treatment for the improvement of plant resistance to abiotic stresses, as noted in earlier studies (Eraslan et al 2008;Li et al 2005). To improve crop yields, our results support the application of Si to control the negative effects of wounding stress to crop plants.…”

Silicon (Si) is essential for normal growth and development in plants and is also beneficial for their responses to wounding. However, the mechanisms by which Si acts to mitigate the effects of wounding is not fully understood. This effect possibly occurs through a reduction in the oxidative stresses associated with wounding. Here, we tested this possibility by investigating the effects of applying different concentrations of Si (0,5 and 1,0 mM) to rice plants under wounding stress for a period of 6 and 12 h. We found that a higher uptake of Si was signifiacntly associated with an increase in leaf chlorophyll contet. In response to wounding induced oxidative stress, the extent of lipid bilayer peroxidation was reduced in a dose-dependent manner by Si application for 6 or 12 h. Activity of the catalase enzyme was initially lowered by Si treatment; however, at 1.0 mM Si, catalase activity increased significantly after 12h of wounding stress. A similar response was also observed for a peroxidase enzyme. Polyphenol oxidase showed a significant reduction in activity. We conclude that Si application does not only improve leaf chlorophyll content but can also overcome the oxidative stress due wounds or physical injuries.

“…Similar results related to the reduction of the ascorbate pool were obtained from cotton (Parida and Das 2005), Cassia angustifolia (Agarwal and Pandey 2004), Critimum maritimum (Ben Hamed et al 2007), spinach (Eraslan et al 2008) and naked oat (Xu et al 2008) under salt conditions. Some studies indicated that under salt stress, the ascorbate pool in cucumber plants (Parida and Das 2005) and non-enzymatic antioxidants in explants of apple (Molassiotis et al 2006) increased.…”

“…Under osmotic stress conditions, plants, in addition to producing antioxidants, also accumulate in the cytosol compatible solutes such as proline that originally were thought to function as osmotic buffers. Proline acts as a mediator of osmotic adjustment, protector of macromolecules such as proteins and membranes, sink for energy, scavenger of free radicals and also as a stress-related signal (Ashraf and Foolad 2007;Eraslan et al 2008;Rahnama and Ebrahimzadeh 2004).…”

Physiological responses to NaCl stress in three wild species of potato in vitro

In this study, responses of wild species of potato to NaCl stress were investigated in vitro. In S. stoloniferum and S. bulbosum, length of the shoot, fresh and dry weight, photosynthetic pigments, K ? concentration, K ? /Na ? ratio, ascorbate pool, anthocyanin, and phenolic and flavonoid compounds were decreased in response to salinity. In these species, salinity increased the level of Na ? , lipid peroxidation, proline and ion leakage percentage. In S. acaule, the length of the shoot, and fresh and dry weight were not affected by salinity. Photosynthetic pigments, Na ? concentration, proline, flavonoid and phenolic compounds quantities were increased and K ? /Na ? ratio were decreased. K ? concentration, lipid peroxidation, ascorbate pool, anthocyanin and ion leakage were not changed by NaCl stress. Superoxide dismutase, guaiacol peroxidase, ascorbate peroxidase and catalase activities were increased in all species. The results suggest that the non-enzymatic antioxidant capacity in S. acaule (salt tolerant) is more important than the enzymatic antioxidant capacity in comparison with the other species.

“…Application of silicon has been reported to be able to control diseases (Rodrigues et al 2003) and pests (Ranganathan et al 2006), alleviate toxicity of some heavy metals (Shi et al 2010), and relieve boron stress (Gunes et al 2007b) and salt stress (Gong et al 2006;Liang et al 2006). Silicon addition markedly reduced MDA concentration in stressed plant species (Liang 1999;Gunes et al 2007c;Eraslan et al 2008). To the best of our knowledge, there is no previous report on micropropagation of C. wilsonii.…”

A simple and efficient micropropagation system was developed for Cotoneaster wilsonii through node and shoot tip explants obtained from mature field-grown plants. Of the two explants, node explants were found to be the most effective for axillary shoot proliferation. The highest frequency of shoot induction was achieved when nodal explants were incubated on Murashige and Skoog (MS) medium supplemented with 0.5 mg L -1 thidiazuron (TDZ) and 0.1 mg L -1 a-naphthaleneacetic acid (NAA) with an average of 34 shoots per explant. The microshoots were separated from the multiple shoots and subcultured on MS medium supplemented with 3% (w/v) sucrose and 0.8% (w/v) agar for further shoot growth. Maximum rooting was obtained on half-strength MS medium supplemented with 0.5 mg L -1 indole-3-butyric acid (IBA). The in vitro-grown plantlets were successfully acclimatized in a glasshouse with 98% of survival. High concentrations of TDZ (1.5-2.0 mg L -1 ) and repeated subcultures resulted hyperhydric shoots. Supplementation of the culture medium with silicon significantly reduced the induction of hyperhydric shoots. Increasing silicon concentration significantly decreased malondialdehyde content of the regenerated shoots. Data indicate that addition of silicon to the culture medium can effectively control hyperhydricity.
