Sammanfattning

Yttrium doping-stabilized gamma-Fe2O3 nanoparticles were studied for its potential to serve as a plant fertilizer and, through enzymatic activity, support drought stress management. Levels of both hydrogen peroxide and lipid peroxidation, after drought, were reduced when gamma-Fe2O3 nanoparticles were delivered by irrigation in a nutrient solution to Brassica napus plants grown in soil. Hydrogen peroxide was reduced from 151 to 83 mu M g(-1) compared to control, and the malondialdehyde formation was reduced from 36 to 26 mM g(-1). Growth rate of leaves was enhanced from 33 to 50% growth compared to fully fertilized plants and SPAD-measurements of chlorophyll increased from 47 to 52 suggesting improved agronomic properties by use of gamma-Fe2O3 nanoparticles as fertilizer as compared to chelated iron.
