The effect of multi-walled carbon nanotubes on morphological and physiological indexes of castor plant (Ricinus communis L.)

Nanotechnology or using technology in the case of atoms and molecules is one of the most important techniques in the present century, which will affect the future of the world economy. This study was designed to examine the effects of multi-walled carbon nanotubes (MWCNTs) (0, 75, 100, 125, 250 and 500 μg ml-1) on morphological and physiological indexes of Ricinus communis L.Measurement of root and shoots dry weight and length showed that increasing of MWCNTs concentrations have an adverse effect on them. Results show that there wasn’t significant difference (p<0.05) between MWCNTs concentration stem length, root length, shoots wet weight, Soluble sugars, and Catalase but there was significant difference (p<0.05) between MWCNTs concentration plant height, phenol, root dry and wet weight, shoots dry weight compared to control and its reason can be found in the effect of different results of MWCNTs in different concentrations on morphologic and physiologic of castor plant.
