“…Watersoluble MWCNT (wsMWCNT) had a significant effect on the growth of Cicer arietinum L. plants (Tripathi et al 2011). The germination rate of corn and rye plants treated with MWCNT was reduced, while the root length was increased (Begum et al 2012(Begum et al , 2014. In the present study, in the concentration of 2 µg · ml the germination percentage increased, quite similar to the control, and the radicle length, in comparison with the control, increased as well.…”

Carbon nanotubes act as regulators of plant germination and growth and are able to change the morphology and physiology of plant cells. The castor plant (Ricinus communis L.) belongs to the Euphorbiaceae family and is a very important medicinal plant. The aim of this study was to investigate the effect of 10 different concentrations of multi-walled carbon nanotubes (MWCNTs) (2, 5, 10, 20, 50, 75, 100, 125, 250 and 500 µg · ml , respectively, and the highest germination rate (53.3%) and the mean germination time (4.6 days) was seen in the concentration of 75 µg · ml -1 . However, no statistically significant differences were found between the different concentrations in any of the germination factors. In the concentration of 100 µg · ml -1 , there was a significant increase in the seedling vigor index I (400) when compared with the concentrations of 5 and 10 µg · ml -1 . The maximum seedling vigor index II (11.3) was found in the concentration of 100 µg · ml -1 and was significantly different from the control and all applied concentrations. The length of radicle in the 100 and 125 µg · ml -1 had a significant increase when compared with the control and the concentrations of 10 and 50 µg · ml -1 . The maximum seedling length (4.6 cm) was seen in the concentration of 100 µg · ml -1 where there was a significant increase with 10 µg · ml -1 . Moreover, in the 100 µg · ml -1 concentration, the largest number of rootlets (8.6) was seen and when compared with the control and concentrations of 5, 10 and 50 µg · ml -1 , there was a statistically significant increase. The maximum wet weight (0.3 g) and dry weight (0.1 g) of seedlings were obtained in the concentration of 100 µg · ml -1 and when compared with the control, there was a significant increase. It was found that in all factors related to the growth of seedlings, the concentrations of 10 and 50 MWCNTs had an inhibitory effect on the response index. The MWCNTs concentration of 100 µg · ml -1 was considered as the optimum concentration in the growth stage of castor seedlings.

“…Bên cạnh những tác động tích cực, cũng có những thông báo cho thấy việc sử dụng các chế phẩm nano kích thích tăng trưởng hoặc làm phân bón lá với nồng độ cao có thể để lại tồn dư trong đất, gây ô nhiễm cho đất trồng sau nhiều vụ gieo trồng (Theng Yuan, 2008;Rico et al, 2011;Begum et al, 2014). Tuy nhiên, việc sử dụng các hạt siêu phân tán có kích thước nano với liều lượng thấp để kích thích hạt giống trước khi gieo giúp cây trồng phát triển khỏe mạnh, tăng năng suất và không tồn tại dư lượng các hạt nano trong nông sản hay trong đất trồng (Churilov et al, 2012;Ngo et al, 2013Ngo et al, , 2014.…”

Seed treatment using metallic nanoparticles to stimulate germination and improve crop yields has been published and widely applied in agriculture production. To assess the safety of such methods on plants, the effectiveness and safety of the treatment of soybean Glycine max L. DT12 seeds with cobalt nanoparticles (nCo) before sowing were investigated. Seeds of soybean cultivar DT12 were treated with nCo at two different concentrations (0.165 and 1.65 mg/kg seed) before sowing. Germination rate, growth speed, soybean yield and bean nutrient components were examined throughout a season. Results implied that at a concentration of 0.165 mg/kg, nCo significantly increased germination rates, plant heights, total pods per plant, number of pods having 3 seeds, and crop productivity compared to both the control and seeds treated with a highter concentration of 16.5 mg per kg of seed. However, no significant differences were found between treatments in terms of growth level and seed nutrient contents, including moisture, ash content, mineral (K, Mg and Fe) and crude protein components. In seeds treated with higher concentration, the Ca content was dramatically lower than that of the control and seeds treated with a low concentration, but bean quality was not affected. This study contributes to the effective and sustainable application of nanomaterials in Vietnamese agriculture.

“…Nowadays, nanomaterials have been wildly used in agriculture as fertilizers, growth regulators, plant protection agents to stimulate crop productivities due to their particularly small size and unique properties (Roduner, 2006;Adhikari et al, 2010). A number of studies focused on the effectiveness and safety of using metal nanoparticles in agriculture production (Alloway, 2008;Sheykhbaglou et al, 2010;Rico et al, 2011;Kole et al, 2013;Begum et al, 2014). Among the micronutritinal elements required for normal plant development, manganese (Mn), copper (Cu), iron (Fe), zinc (Zn), boron (Bo), chlorine (Cl), molybdenum (Mo), and cobalt (Co) are essential for the growth of plants (Alloway, 2008).…”

“…There are also several studies to evaluate the undesirable effects of nanomaterials on plants and indicated that the majority of nanoparticles were beneficial or have no significant effect on plant growth; adversely effects on certain crops were reported in limited casses (Rico et al, 2011;Begum et al, 2014). When evaluating the possible toxicity of the five nanoparticles, Lin & Xing (2007) found that only Zn and ZnO nanoparticles inhibited germination and root development in six plant species.…”

Recently, metal and other nanoparticles have been widely used to improve crop growth and development, reduce used chemical amount, increase safety of agricultural products and prevent soil and water pollution. Seed treatment technology with metal nanoparticles to stimulate seed germination and improve crop yields has been reported in several studies. In order to assess the safety of the use of metal nanoparticles in agriculture production, in this study the effect and safety of seed treatment with nanoparticles (nCu) prior to sowing on the germination, growth, development, productivity and quality of maize (Zea mays L.) were evaluated in the field conditions. Seeds of maize cultivar LVN 092 were treated with nCu at different concentrations before planting. Germination and plant growth rates, plants yield and grain nutrition were monitored and evaluated. The obtained results showed that treatment of maize seed with nCu at a concentration of 20 mg/kg seed increased germination after 7 days of sowing as well as the theoretical and actual yields compared to the control and the treatment of 1000 mg nCu/1 kg seeds. Other agricultural characteristics, such as the development rate, plant height, grain nutritional content including moisture, ash, total fiber, crude protein, minerals were not significantly between treatments and the control. Therefore, the seed treatments with metal nanoparticles can be contribute to improve agriculture production without impact to quality of crops.
