- Abstract
Nanoparticles (NPs) in agricultural systems can potentially be used as appropriate candidate for change in growth, development, productivity, and quality of plants. In the present study, we assessed the effect of TiO NP concentrations (0, 2, 5, and 10 ppm) on changes of membrane damage indexes like electrolyte leakage index (ELI) and malondialdehyde (MDA) during cold stress (CS) 4 °C in sensitive (ILC 533) and tolerant (Sel 11439) chickpea ( Cicer arietinum L.) genotypes. Aggregation of NPs within the vacuole and chloroplast indicated absorbed NPs in seedlings. Bioaccumulation of NPs showed that, under thermal treatments, the sensitive genotype had more permeability to NPs compared to the tolerant one, and TiO content was higher during CS compared to optimum temperature. Physiological indexes were positively affected by NP treatments during thermal treatments. TiO NP treatments (especially 5 ppm) caused a decrease in ELI during thermal treatments, whereas ELI content under CS treatment increased at 0 ppm TiO in both genotypes. Under thermal treatments, although the genotype 11439 showed lower accumulation of MDA than ILC 533 genotype, a significant decrease was observed in MDA content at 5 ppm TiO. Results showed that TiO treatments not only did not induce oxidative damage in sensitive and tolerant chickpea genotypes but also alleviated membrane damage indexes under CS treatment. It was suggested for the first time that TiO NPs improved redox status of the genotypes under thermal treatments. New findings possibly would reveal the use of NPs generally or TiO NPs especially for increase of cold tolerance in crops.
