“…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. MWCNT increased the wet weight and the length of the wheat seedling roots, but it had no effect on seed germination and stem length (Wang et al 2012;Tiwari et al 2014). In the present study, carbon nanotubes had no effect on the germination of castor seeds and the length of plumule.…”

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.

“…On the other hand there exist contradictory reports that show the toxicity of CNTs to the growth of a number of different plants (Begum et al 2012;Lin and Xing 2007). MWCNT reduced the root fresh weights (FW) of rice and cucumber seedlings while the root lengths (RL) varied in a nonorderly manner with MWCNT concentration (rice) or decreased (cucumber) (Begum et al 2012); the germination rate of maize and rye grass decreased with 2,000 mg/l of MWCNT but their RLs increased (Lin and Xing 2007); MWCNT increased the FW and RLs of wheat seedlings but had no effect on seed germination and shoot lengths (SL) (Wang et al 2012).…”

“…The dependence of seedling growth on the first three factors is well known in plant physiology. An assortment of media have been used in the aforesaid works-wet filter paper (Mondal et al 2011;Lin and Xing 2007;Wang et al 2012), agar with MS nutrients (Khodakovskaya et al 2009;Villagarcia et al 2012) and hydroponics with Hoagland's nutrients (Begum et al 2012) or without (Tripathi et al 2011). Pristine MWCNTs are hydrophobic and form aggregates in aqueous media that reduce their aspect ratio and hence their effectiveness.…”

“…Pristine MWCNTs are hydrophobic and form aggregates in aqueous media that reduce their aspect ratio and hence their effectiveness. To disperse their CNTs the researchers in the aforesaid studies had functionalised their CNTs with different hydrophilic groups (Khodakovskaya et al 2009;Villagarcia et al 2012;Mondal et al 2011;Tripathi et al 2011) or had used a surfactant (PEG) (Villagarcia et al 2012), and had used different protocols for ultrasonication (Khodakovskaya et al 2009;Villagarcia et al 2012;Mondal et al 2011;Tripathi et al 2011;Lin and Xing 2007;Wang et al 2012). Functionalization and micellar cage formation by a surfactant (Vaisman et al 2006) alter the surface chemistry of the CNT, which changes the way it interacts with the plant (Villagarcia et al 2012).…”

Interfacing carbon nanotubes (CNT) with plants: enhancement of growth, water and ionic nutrient uptake in maize (Zea mays) and implications for nanoagriculture

et al. 2013

The application of nano-biotechnology to cropscience/agriculture ('nanoagriculture') is a recent development. While carbon nanotubes (CNTs) have been shown to dramatically improve germination of some comestible plants, deficiencies in consistency of behavior and reproducibility arise, partially from the variability of the CNTs used. In this work, factory-synthesized multi-walled-CNTs (MWCNTs) of quality-controlled specifications were seen to enhance the germinative growth of maize seedlings at low concentrations but depress it at higher concentrations. Growth enhancement principally arose through improved water delivery by the MWCNT. Polarized EDXRF spectrometry showed that MWCNTs affect mineral nutrient supply to the seedling through the action of the mutually opposing forces of inflow with water and retention in the medium by the ion-CNT transient-dipole interaction. The effect varied with ion type and MWCNT concentration.

“…Over last few years, there have been extensive studies to understand the influence of nanomaterials on the growth of different types of plants (Khodakovskaya et al 2009;Khodakovskaya et al 2013a, b;Lu et al 2002;Cañas et al 2008;Yang et al 2006;Hong et al 2005a, b;Tan et al 2009;Yuan et al 2011;Khodakovskaya et al 2013a, b;Mahajan et al 2011;Wang et al 2012;Larue et al 2012;Miralles et al 2012;Feizi et al 2012;Tripathi et al 2011;Sonkar et al 2012). Khodakovskaya et al (2009Khodakovskaya et al ( , 2013a demonstrated that at very low doses MWCNT can penetrate the seed coat and enhance the germination of tomato plant.…”

Influence of water soluble carbon dots on the growth of wheat plant

The effect of water soluble carbon nano-dots (wsCND) on the growth of root and shoot of wheat plants under light and dark conditions has been studied. The wsCND enhances the growth of root and shoot both in light and dark conditions. The effect of wsCND on the growth of root was relatively more compared to that of shoot. Scanning electron and Fluorescence microscopic analysis show that wsCNDs enter inside the plant. Raman spectroscopy also confirms this. The present study shows that wsCNDs are non-toxic to the wheat plant and can be used to enhance the production of this cereal crop.
