Abstract

Background

The application of nanoparticles (NPs) in horticultural crops is in a tremendous increase. NPs help in the overcoming of stresses with positive impacts on plant growth and development. Silver NPs (AgNPs) have numerous pre- and postharvest applications in agriculture.

Aims and methods

This study aimed to evaluate the effect of AgNPs application (0, 50, 100, 150, and 200 ppm) at three spray intervals (5, 10, and 15 days) on the morphological and compositional traits, and defense system of strawberry.

Results

Results showed that AgNPs application enhanced the growth, yield, quality, and nutritional aspects of strawberry grown under field conditions. Shoot fresh weight (20.20 g) and leaf number/plant (41.53) were enhanced at 100 ppm AgNPs and 15 days interval. A stunted growth of strawberry plants was recorded at 200 ppm AgNPs. Moreover, a 15-day-spray interval was found optimum for the improvement of major morphological traits. Fruit size, yield, total soluble solids, acidity, and antioxidant capacity were improved at 50 and 100 ppm AgNPs. The activation of plant defense system, that is, superoxide dismutase, peroxidase, catalase, total soluble protein, and ascorbic acid was improved under AgNPs foliar application. The activation of stress indicating marker malondialdehyde outlined a high defense response of strawberry at 150 ppm AgNPs.

Conclusions

Conclusively, AgNPs application at 50, 100, and 150 ppm can be considered effective for sustainable strawberry production.
