“…Similar results have been reported by other researchers confirming the positive effects of silicon in reducing salt stress [41][42]. Actually, nanosilicon particles can improve water absorption and distributions in plants due to their hydrophilic characteristics and high absorption surface [43].…”

A greenhouse experiment was conducted to evaluate the effects regarding inoculation of exopolysaccharide (EPS)-producing bacterium, the extracted EPS and silicon nanoparticles on Solanum lycopersicum L. seeds under salinity stress, in a completely randomized factorial design with three replicates. The inoculated seeds with silicon nanoparticles (8 gr L -1 ), bacterial EPS (0.01 M), and 1 mL of bacterial suspension (1×10 8 CFU mL -1 ) were sown in pots and irrigated with water at different salinity levels (0.3, 2, 4, 6, and 8 dS m -1 ). Results showed that treatment application could enhance salinity tolerance of tomato seeds and improve plant growth so that combined treatments of EPS and silicon nanoparticles (S.E.N), bacteria and silicon nanoparticles (S.B.N), and EPS with silicon nanoparticles and bacteria (S.E.B.N) were the best treatments for plant growth and improvement regarding salinity levels. The mentioned treatments significantly (p<0.01) increased root and shoot fresh or dry weight in comparison to the control sample. In addition, treatments significantly (p<0.01) decreased proline content and antioxidant enzyme activities. Thus, it can be concluded that applied treatments are suitable for agricultural and environmental applications and bring about less damage caused by salinity stress.

“…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.…”

“…The results indicated that Si is capable of diminishing the accumulation of Na in the plant tissue, but were not conclusive with respect to the responses of enzyme activity to Si. 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.…”

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.

“…O Si é um elemento que confere às plantas maior resistência a estresses bióticos e abióticos (Goto et al, 2003;Romero-Aranda et al, 2006;Hattori et al, 2007;Côté-Beaulieu et al, 2009;Savvas et al, 2009;Hashemi et al, 2010), assim como melhora o manejo fitossanitário de cafeeiros (Reis et al, 2008) e plantas de trigo (Zanão Júnior et al, 2010).…”

RESUMOO benefício do silício (Si) no crescimento de plantas cultivadas tem sido observado em vários trabalhos. O objetivo deste estudo foi avaliar os efeitos de Si no crescimento de mudas de cafeeiro cv. Catuaí Vermelho. O experimento foi conduzido em vasos, e as plantas crescidas em casa de vegetação, sem restrição hídrica. A partição de matéria seca entre raízes, caule e folhas, os teores de nutrientes e Si nos tecidos vegetais e no solo e as trocas gasosas foliares foram avaliados em plantas submetidas a doses de silicato de cálcio correspondentes a 0 (controle), 1,5 e 6 Mg ha -1 . O delineamento experimental foi em blocos casualizados, com três tratamentos e 3, 4 ou 18 repetições, dependendo da variável considerada. Cada parcela experimental era composta por uma planta. Em relação à altura e matéria seca total, as plantas de todos os tratamentos apresentaram desenvolvimento satisfatório, com incrementos diários compatíveis com o esperado em cafeeiros bem nutridos. Os tratamentos com silicato de cálcio causaram aumento nos teores de Ca no solo e na planta e de Si no solo. Considerando que o único nutriente alterado pelos tratamentos foi o Ca e que os teores observados na planta podem ser considerados não prejudiciais, as respostas descritas a seguir são consequência do alto teor de Si no solo. Após 130 dias do início do experimento, as plantas tratadas com 6 Mg ha -1 de silicato de cálcio apresentaram menor acúmulo de matéria seca nas raízes e aumento da relação entre a matéria seca da parte (1) Recebido para publicação em julho de 2010 e aprovado em março de 2011.
