“…Consistent data are known for Cd+Si treated rice (Nwugo & Huerta 2008). Similarly, Si improved the growth of maize exposed to Cd (Vaculík et al 2009). Screening of thirty Zea mays (L.) hybrids, cultivated in central Europe, showed differences in the sensitivity, accumulation capability and translocation of Cd.…”

“…On the contrary, addition of Si considerably increased root Zn concentrations in both cultivars at different degrees, especially in the cultivar resistant to high Zn (Song et al 2011). Influence of Si on Cd concentration in maize has been observed by Vaculík et al (2009). Cadmium concentration in below-and aboveground plant parts and the total amount of Cd per plant were significantly higher in the Cd+Si plants than in the Cd treatment.…”

“…For example, Si plays an important role in increasing the resistance of plants to pathogenic fungi (Fauteux et al 2005;Resende et al 2009). Silicon also mitigates cadmium inhibitory effects in rice and maize plants (Nwugo & Huerta 2008;Vaculík et al 2009). This positive influence also has been recorded in the case of other metals and plant species, e.g.…”

The aim of this study was to determine the effect of exogenously applied Si on the growth and physiological parameters of sorghum [Sorghum bicolor (L.) Moench] cultivated in hydroponics with elevated zinc concentrations (75 µM and 150 µM Zn). Increased concentrations of Zn inhibited root growth and biomass production of roots and shoots. Application of Si individually showed a positive effect on root growth but negatively affected production of fresh and dry biomass of roots and shoots. On the other hand, silicon in combination with Zn significantly reduced the inhibitory effect of Zn on root growth but did not positively affect biomass production of roots and shoots. Accumulation of Zn in plant tissues increased with increasing Zn concentration in nutrient solution, but application of Si in combination with Zn did not significantly influence Zn accumulation in roots. Completely opposite results were found in Si accumulation in roots treated with Si in combination with Zn. Interaction of these ions resulted in considerable increase of Si accumulation in roots which almost doubled in comparison to individal Si treatment. Impact of Zn on the activity of some antioxidant enzymes was equivocal and differences were observed also between two Zn concentrations. Individual application of Si resulted in significant increase in the activity of all studied antioxidant enzymes but Si in combination with Zn mostly negatively affected their activity except the activity of catalase (CAT) which was the highest in roots grown in solution containing both Si and Zn ions. Comparing all obtained data we can assume that Si applied in combination with Zn did not significantly alleviate Zn toxicity in young sorghum except the growth of primary seminal root and further experiments are required for better understanding of their interaction.

“…When cadmium (Cd) was present in the medium, Casparian bands, as well as suberin lamellae, developed closer to the root apex in Karwinskia humboldtiana (Zelko & Lux 2004) and Silene dioica (Martinka & Lux 2004). Similarly, enhanced suberinization in the endodermis was observed by Vaculík et al (2009) in Cd-treated maize roots. In another study, Vaculík et al (2012) found that both Casparian bands and suberin lamellae in exo-and endodermis of Salix caprea roots developed closer to the root apex in roots exposed to elevated Zn or Zn+Cd when compared with the control.…”

Poplar is one of the suitable candidates for phytoremediation due to extensive root system, fast growth rate, easy propagation and high biomass production. Zinc (Zn) is an essential element, but at high concentration becomes toxic to plants, similarly like cadmium (Cd). In order to evaluate the effect of Zn on root tissue development we conducted experiments with poplar (Populus ×euramericana clone I-214) grown in hydroponics. Plants were treated with low (control) and excess level of Zn (1 mM). Changes in the development of apoplasmic barriers -Casparian bands and suberin lamellae in endodermis, as well as lignification of xylem vessels have been investigated. We found that both apoplasmic barriers developed closer to the root apex in higher Zn-treated root when compared with control root. Similar changes were observed in lignification of xylem vessels. For localization of Zn within root tissues, cryo-SEM/EDXMA analyses were used. Most of Zn was localized in the cortical tissues and four-time less Zn was determined in the inner part of the root below the endodermis. This indicates that endodermis serves as efficient barrier of apoplasmic Zn transport across the poplar root.

“…Azimi et al [38] and Lu et al [39] also showed that the application of silicon nanoparticles significantly increased germination percentage and dry weights of roots and shoots of wheat and soybean, respectively. According to Vaculik et al [40], silica improves plant growth by increasing cell elongation and expanding primary cell walls. Similar results have been reported by other researchers confirming the positive effects of silicon in reducing salt stress [41][42].…”

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.
