Carbon nanotubes as plant growth regulators prospects
Nanotechnology has contributed to agriculture for two decades as an advanced technology with excellent potential in the production systems. Under laboratory, greenhouse, and field conditions, a variety of nanomaterials have been tested with different dosages, size of nanoparticles, exposure time, substrate media, and application methods to evaluate their effects on physiological and biochemical characteristics of different edible or nonedible plants. However, the use of carbon nanotubes (CNTs) is still little studied as plant growth regulators. These nanomaterials have been successfully encapsulated to release fertilizers and herbicides to a secure manner because recent studies have shown positive results on the seed germination, root and stem length, chlorophyll, and length plant, among others. Nevertheless, in the literature, there are contradictions regarding the consequence of the different physical and chemical properties of CNTs that affect the interaction with plants. In this chapter, some benefits and disadvantages related to the adsorption, uptake, transport, accumulation, and transformation or degradation of CNTs and their biochemical and physicochemical interactions between CNTs and plants are shown and discussed. Besides, the effects of spreading CNTs in agricultural soils on human beings, plants, and environmental health are also discussed since a prospect vision.
