Summary
Nanofertilizers like nano-Fe, -Zn, and -Cu boost wheat
Area of Science:
- Agricultural Science
- Plant Science
- Nanotechnology
Background:
- Modern agriculture increasingly uses nanofertilizers for crop yield and pest management.
- Understanding nanofertilizer effects on plant physiology and pest interactions is crucial.
- Wheat green aphid (Schizaphis graminum) is a significant agricultural pest.
Purpose of the Study:
- To investigate the impact of nano-Fe, nano-Zn, nano-Cu, and urea (N) fertilizers on wheat antioxidant systems.
- To assess the effects of these nanofertilizers on the antioxidant activities of wheat plants and the green aphid Schizaphis graminum.
- To evaluate the role of nanochelating technology in nanofertilizer synthesis and efficacy.
Main Methods:
- Wheat plants (cv. Chamran) were treated with nano-Fe, nano-Zn, nano-Cu, and urea fertilizers.
- Antioxidant activities (phenolics, H2O2, POX, CAT, SOD) were measured in wheat plants and S. graminum.
- Plants were subjected to aphid infestation to simulate pest pressure.
Main Results:
- Nano-Zn treatment significantly increased phenolic levels in non-infested wheat plants.
- Nano-Zn and nano-Fe treatments elevated H2O2 levels in wheat plants under infestation.
- Nanofertilizers differentially affected antioxidant enzyme activities (POX, CAT, SOD) in both wheat and aphids, with some treatments reducing activity in aphids.
Conclusions:
- Nanofertilizer application enhances the antioxidant system in wheat plants.
- Nanofertilizers contribute to increased resistance of wheat against the green aphid S. graminum.
- The study highlights the potential of nanochelating technology in developing effective nanofertilizers for sustainable agriculture.

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

02:11The Roles of Bacteria and Fungi in Plant Nutrition
36.1K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
