Effect of Molybdenum on Chlorophyll Content of Wheat
In higher plants, chlorophyll plays a role in aggregating light energy and converting light energy into chemical energy through photosynthesis and supplying it to other processes that require energy. The chlorophyll content is directly measured using a chlorophyll meter. The lack of nutrient elements in plants often leads to changes in leaf color, indicating that nutrient elements are important for chlorophyll metabolism. Studies have shown that the lack of molybdenum during the growth of wheat will make wheat yellow. Using the chlorophyll meter for further studies and understanding of molybdenum-induced reduction in chlorophyll content and yellowing of winter wheat, the SPAD502 Chlorophyll meter is used for further understanding of the changes.
The chlorophyll meter was used to analyze the variation of wheat lacking molybdenum, and the lack of molybdenum resulted in a significant decrease in chlorophyll content of winter wheat. Therefore, the use of molybdenum should be increased during the planting process to increase the chlorophyll content. The effects of molybdenum deficiency on chlorophyll content in winter wheat in different periods were different. Through analysis, it was found that there was no difference in chlorophyll content between molybdenum-deficient and molybdenum-treated when the temperature was higher, indicating that molybdenum deficiency at low temperatures could easily cause significant chlorophyll content. decline.
Through the further analysis and understanding of the effects of molybdenum deficiency on wheat, it was found that the winterization of winter wheat was due to the decrease of low-temperature and molybdenum chlorophyll content, and the decrease in chlorophyll content was not the result of decomposition, but may be due to the obstruction of chlorophyll synthesis. Therefore, the chlorophyll meter can be used to measure whether the lack of molybdenum is found after wheat yellowing is found. At the same time, the chlorophyll meter can guide us to apply fertilizers rationally. In terms of nitrogen fertilizers, we can reduce the nitrogen fertilizer use by 10% while ensuring that the production will not be reduced.
