Impact of foliar Nano-DAP on nitrogen metabolism in wheat seedlings in vitro

Nano-DAP are known to enhance plant defence and metabolism. In this study, a foliar application of Nano-DAP was applied in varied concentrations (2-6 ml/L), to 14-day-old wheat seedlings in vitro. To evaluate the responses of Nano-DAP on nitrogen metabolism in wheat, key enzymes were targeted to be checked at 8 hours after foliar application. Results showed significant increases in nitrate reductase (NR) and glutamine synthetase (GS) activities, along with varied free amino acid (FAA) levels and chlorophyll content, compared to conventional DAP (2%, w/v) as well as control. These findings suggest that Nano-DAP enhances nitrogen assimilation and photosynthetic efficiency, demonstrating its potential as a plant metabolic enhancer.
