The influence of L-Methionine (L-MET under field conditions revealed that nitrogen availability influenced ethylene production, leaf tissue nitrogen concentration, photosynthetic attributes, and growth in wheat. Ethylene production in the control (75 mg of N per kg soil) was two times greater than the treatment with high N concentration (150 mg N per kg soil). All the parameters showed the maximum increase with 20 mg L-MET per kg soil. The results are suggestive of the fact that the application of L-MET greatly increased relative growth rate (RGR), total leaf area, net photosynthesis and leaf tissue N concentration, depending on the concentration of soil available nitrogen.
