Effects of different nitrogen supply levels and ammonium nitrate ratios on the growth and nitrogen metabolism of edible grasses
This study explored the nitrogen utilization mechanism of edible grass to support the breeding of nitrogen-efficient varieties. A hydroponic system was established with five nitrogen concentration gradients and five ammonium nitrate ratios , all at 136.59 mg/L nitrogen. At the cultivation end, growth performance, nitrogen metabolism, and photosynthetic efficiency were analyzed. Transcriptome sequencing was conducted on N1, N3, and T3 treatments to reveal nitrogen-efficient use mechanisms, laying a foundation for genetic improvement.
