Abstract
Salinity stress is a major limitation to global crop production. Wheat is one of the world’s crops has salt sensitive characteristics than other crops. Meanwhile, rapid advancement of nanotechnology is introducing more and more engineered nanoparticles (ENPs) in agricultural soil . While some negative effects of ENPs on plant health at very high concentrations have been reported, more beneficial effects at low levels are increasingly noticed. Calcium phosphate nanoparticles (CPNPs) are one of the most widely used nanoparticles to interact with ecosystem and of great interest in agricultural sciences. The current study evaluates the effect of Calcium phosphate nanoparticles on germination percentage and early growth rate of wheat (Triticum durum L.) germinated under sodium chloride stress. As compared to the control, the results clearly showed that germination percentage not affected after NPs treatments whereas growth, fresh mass and dry mass of seedlings were highly increased at low levels of CPNPs . As salt concentration increased, chlorophyll a, b and carotenoids contents decreased. The results revealed that CPNPs interacted with salt stressed seedlings caused an increasing in photosynthetic pigments as compared to the control.
Highlights
Nanotechnology is a very promising field of science and technology possesses exceptional physical and chemical properties that has the potential to open up new applications in the field of agriculture and biotechnology Stamploulis et al [1]
Fertilizers are very important for plant growth and development, most of the applied fertilizers are unavailable to the plants due to many factors such as hydrolysis, degradation, photolysis and leaching
Upadhyaya et al [11] showed that Calcium phosphate nanoparticles may help in the formulation of new nano growth promoter and nanofertilizers for agricultural use
Summary
Nanotechnology is a very promising field of science and technology possesses exceptional physical and chemical properties that has the potential to open up new applications in the field of agriculture and biotechnology Stamploulis et al [1]. The use of nanoparticles in the germination and growth of plants and for the control of stress plants is a recent practice Mahajan et al ; Ahmed and Awwad [5,6]. Lieu and Lal [9] reported positive impact of nanoparticles on plant with its potential to be used as future nanofertilizer. Upadhyaya et al [11] showed that Calcium phosphate nanoparticles may help in the formulation of new nano growth promoter and nanofertilizers for agricultural use. It could potentially help in reduction of the quantity of fertilizer applied to crops. There is little experimental evidence on the interaction between nanoparticles and salt-stressed plant species, the proposed research is to understand the interaction between Calcium phosphate nanoparticles and wheat plant under salt stress conditions
