“…However, when we observed the pigment content at 1% NaCl, we noted that even using 1.0g L -1 of Si, it is not possible to increase the pigment content, indicating that the stress imposed to the plants was sufficient high enough to cause severe damage. These results corroborated the SOUNDARARAJAN et al (2013) ones who observed an increase in the contents of chlorophyll a, b and total in sage leaves under lower concentration of NaCl and the presence of Si. In higher concentrations of salt, the pigments content were not increased, even when used high doses of Si.…”

Salt stress is one of several major abiotic stresses that affect plant growth and development, and there are many evidences that silicon can ameliorate the injuries caused by high salinity. This study presents the results of an assay concerning: (1) the effect of in vitro NaCl-induced salt stress in cape gooseberry plants and (2) the possible mitigating effect of silicon in saline conditions. For that, nodal segments were inoculated in Murashige and Skoog (MS) medium under salinity (0.5 and 1.0% NaCl) with different silicic acid concentrations (0, 0.5 and 1.0g L-1). Phytotechnical characteristics, photosynthetic pigments content, and leaf anatomy were evaluated after 30 days. Shoot length, root length, number of leaves and buds, fresh and dry weight, pigment content, stomatal density and leaf blade thickness were drastically reduced by increased salt level. The supply of silicon (1.0g L-1) has successfully mitigated the effect of salinity at 0.5% NaCl for chlorophyll, carotenoids, stomatal density and leaf blade thickness. When salt stress was about 1.0%, Si was not effective anymore. In conclusion, we affirmed that, in in vitro conditions, salt stress is harmful for cape gooseberry plants and the addition of silicon showed effective in mitigating the saline effects of some features.

“…The plants grown at 50mMNaClwith 50 or 100 mg/l potassium silicate helped the plants to overcome the adverse effect of salt and enhanced growth and salt stress tolerance capacity of Salvia splendens (Soundararajan et al 2013). The problem of hyperhydricityduring tissue culture experiments which was reported during the micropropagation of Cotoneaster wilsonii was reduced by silicon supplementation (Sivanesan et al 2011).Fuchsia, Petunia and Toreniawere reported to have an increase in flower diameter whereas Bacopa and Verbena had thicker leaves with silicon supplementation (Mattson and Leatherwood, 2010).…”

Silicon has been considered as beneficial element for the plants. The supplementation of silicon as nutrient to the plants may play a significant role which includes increase in crop growth and yield, improvement of leaf exposure to light, decreased susceptibility to pathogens and pests and amelioration to abiotic and biotic stresses. The most significant effect of silicon on plants, besides improving their fitness in adverse environmental conditions and increasing agricultural productivity of plants is the restriction of pest attack and prevention of diseases. Unfortunately the significance of silicon nutrition in crop production and mitigation of abiotic and biotic stresses remains unexplored. Hence there is an urgent need to use silicon fertilizers for improvement in crop production. The understanding of the beneficial effects of silicon is important to improve crop productivity as it may enhance plant nutritional value for a growing world population.

“…Salt (salinity) stress may also affect electron transport, photophosphorylation and enzymatic activities (Fadzilla et al 1997 ;Liang 1999 ;Steduto et al 2000 ). Inclusion of Si has widely been reported to signifi cantly increase the growth of many plant species through increasing photosynthetic activity, leaf area and chlorophyll content and improving chloroplast structure in salt-stressed plants (Liang et al 1996 ;Liang 1998 ;Yeo et al 1999 ;Al-Aghabary et al 2004 ;Zhu et al 2004 ;Romero-Aranda et al 2006 ;MurilloAmador et al 2007 ;Tuna et al 2008 ;Savvas et al 2009 ;Hashemi et al 2010 ;Lee et al 2010 ;Tahir et al 2012 ;Kafi and Rahimi 2011 ;Bae et al 2012 ;Yin et al 2013 ;Soundararajan et al 2013 ;Haghighi and Pessarakli 2013 ). Indeed, Liang et al ( 1996 ) showed that the addition of Si could signifi cantly enhance dry matter yields of both salt-sensitive (cv.…”

Silicon (Si) has widely been reported to increase plant tolerance and/or resistance to salt (salinity) stress, but the underlying mechanisms remain poorly understood. This chapter reviews the updated knowledge concerning Si and salt (salinity) interactions in higher plants. Based on the current literature, it seems that (1) silica deposited in the apoplast as SiO 2 opal or phytolith can enhance water retention by inhibiting transpirational water loss, thus reducing salt-induced osmotic stress, and (2) soluble Si in the symplast may be actively involved in physiological and biochemical metabolisms by regulating the expression of genes related to the biosynthesis of hormones (ABA and JA etc.), antioxidant defence enzymes, H + -pumps and osmolytes to rebalance ion stoichiometry, reduce membrane permeability, and improve membrane structure and stability, hence improving salt tolerance in plants. However, further work is needed to better understand Si-mediated tolerance and/or resistance to salt stress at the molecular level.
