Exposing wheat seedlings to different levels of calcium can affect how well they absorb nitrogen. In this study, wheat plants were given solutions with varying amounts of calcium, and their nitrogen assimilation enzymes were measured. The results showed that a calcium concentration of 4 mmol·L-1 was the most effective in increasing the plants' ability to absorb nitrogen. At this level, the activity of the enzyme responsible for nitrogen assimilation was highest. Higher or lower calcium concentrations had varying effects on different enzymes involved in nitrogen assimilation. Overall, the study suggests that calcium plays a crucial role in enhancing wheat plants' ability to take up nitrogen, with 4 mmol·L-1 being the optimal concentration for this process.
