“…These results are in agreement with previous reports regarding the beneficial effects of Si on the growth and yield of Sorghum bicolor (L.) Moench under salt stress (Yin et al, 2013) and wheat cultivars under coldstress (Liang et al, 2008) conditions. Chillingsensitive plants exposed to low temperature often exhibit signs of water stress due to decreased root hydraulic conductance, leading to associated decreases in leaf water and turgor potential, followed by a reduction of growth (Waśkiewicz et al, 2014).…”

Low temperature is one of the major adverse climatic factors that suppress plant growth and sustainable agricultural development. In these climate conditions, silicon (Si) can mitigate various abiotic stresses including low temperature. In this study, the roles of foliar-applied silicon (10 mM potassium metasilicate) in enhancing tolerance to chilling stress were investigated in maize (Zea mays 'Fajr') plants. The low temperature stress caused significant reduction of plant growth and relative water content; however, Si ameliorated these effects. Si supply in maize exhibited a significantly positive effect on accumulation of free amino acids, and reduced the necrotic leaf area. The decrease in maximum quantum yield of PSII (F v /F m ) was reversible during recovery, but not in the non-Si-treated leaves. This can be explained by enhancement of protective pigments; carotenoid and anthocyanin leading to the protection of PSII from damage. Additionally, analysis of OJIP transients revealed that Si reduced cold damaging effect on performance index (PI abs ) and F v /F m through improvement of excitation energy trapping (TR 0 /CS) and electron transport (ET 0 /CS) per excited crosssection of leaf. The malondialdehyde (MDA) concentration, which was significantly increased under chilling stress, was decreased by Si. The reduced glutathione and ascorbate concentrations were higher in Si-treated plants as compared to those without application of Si under chilling stress. These results indicated that Si could enhance the chilling stress tolerance of maize plants through improving the biomass accumulation, maintaining a high level of glutathione, ascorbic acid, protein, protective pigments, and enhancing the photochemical reactions. This study also suggests that the foliar-applied Si increases recovery ability from chilling injury. Nizka temperatura je eden izmed glavnih neugodnih klimatskih dejavnikov, ki zavira rast rastlin in trajnostni razvoj kmetijstva.V takšnih klimatskih razmerah lahko silicij oblaži abiotski stress vključno z učinki nizke temperature. V tej raziskavi je bila preučevana vloga foliarnega dodajanja Si (10 mM kalijevega metasilikata) pri povečevanju odpornosti koruze (Zea mays 'Fajr') na hladni stres. Stres zaradi nizkih temperature je značilno zmanjšal rast in vsebnost vode v rastlinah, kar je dodajanje Si oblažilo. Dodatek silicija je sprožil v koruzi značilne pozitivne učinke v kopičenju prostih amino kislin in v zmanjšanju nekrotičnosti listov. Zmanjšanje v fotokemični učinkovitosti PS II (F v /F m ) je bilo povratno med okrevanjem, vendar ne pri rastlinah, ki niso bile tretirane s silicijem. To bi lahko razložili s povečanjem vsebnosti zaščitnih pigmentov karotenoidov in antocianinov, kar vodi v zaščito PSII pred poškodbami. Dodatno so analize prehodne fluorescence klorofila a (OJIP) odkrile, da je dodatek Si zmanjšal učinek poškodb zaradi hlada na fotosintetski elektronski transport (PI abs in F v /F m ) preko boljšega prestrezanja ekscitacijske energije (TR 0 /CS) in boljšega elektronskeg...

“…These results support Yin et al (2013) in studies involving the Si application to mitigate the detrimental effect of salinity in sorghum, and Cessa et al (2011) in studies involving different P and Si rates in sorghum. In these studies, both authors verified that Si did not affect the plants' vegetative growth under normal cultivation conditions.…”

The forthcoming of silicon (Si) highly soluble sources provided a suitable alternative to Si use in agroecosystems. There are many benefits associated to Si application in crops, such as improvement in feed quality. In this sense, the aim of this work was to evaluate the effect of Si foliar application on physiological quality, biomass production, and silicon accumulation in Sorghum bicolor. The experiment was conducted under greenhouse condition using an entirely randomized design, with five Si rates (0 as control), 0.84, 1.68, 2.52, and 3.36g L -1 of Si) applied as potassium and sodium silicate, with four repetitions. In each treatment, applied solutions were balanced in potassium in order to isolate the Si effect. The following measurements were taken: growth, biomass production, Si accumulation, and physiological quality. Supplying Si via leaves did not affect the sorghum growth rate and the relative chlorophyll index; however, leaf area increased 23% with the use of 2.36 g L -1 of Si. Physiological variables are influenced by increasing Si rates, with rates close to 1.68 g L -1 of Si causing the best photosynthetic rates and stomatal conductance. The use of potassium silicate as a source of silicon is an alternative for productivity increases up to 30%, but an economic study on the viability of its commercial application in the production chain of Sorghum bicolor is necessary.

“…It was also reported that addition of Si signifi cantly enhanced leaf concentrations of chlorophyll a and b in wheat plants grown hydroponically with supply of 100 mM NaCl (Tahir et al 2012 ). While Si application per se (in the absence of salt stress) did not infl uence the net photosynthetic rate, stomatal conductance and transpiration rate in hydroponically grown sorghum ( Sorghum bicolor ) seedlings, Si supplementation caused a signifi cant increase in these parameters when plants were subjected to salt stress at 100 mM NaCl (Yin et al 2013 ). Ashraf et al ( 2010 ) showed that the yield and yield attributes of sugarcane ( Saccharum offi cinarum ) under salt stress were signifi cantly higher in the presence of Si than in the absence of Si.…”

“…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.
