Impact of foliar chitosan and its oligomer on nitrogen metabolism in wheat seedlings in vitro

DOI: 10.22161/ijeab.104.9

Abstract:
Chitosan and its oligomers are known to enhance plant defense and metabolism. In this study, a foliar application of 400 ppm chitosan was applied to 14-day-old wheat seedlings. Enzyme activity and physiological parameters were measured 8 hours post-treatment. Results showed significant increases in nitrate reductase (NR) and glutamine synthetase (GS) activities, along with elevated free amino acid (FAA) levels and chlorophyll content, compared to control. These findings suggest that chitosan enhances nitrogen assimilation and photosynthetic efficiency, demonstrating its potential as a plant metabolic enhancer.
