What external factors influence the chlorophyll content in plant leaves
The green leaves of higher plants are the main organs of photosynthesis. Chloroplasts are the organelles that carry out the core reactions of photosynthesis. Photosynthesis energy conversion and carbon assimilation processes are performed in them. The chlorophyll content of chloroplast directly affects the growth and development of plants. Therefore, the regulation of leaf chlorophyll content is one of the important indicators that reflect the changes of leaf physiological activity. Therefore, the measurement of chlorophyll content has a certain use value, and the rapid non-destructive measurement of chlorophyll content can be performed using the chlorophyll meter for operation and analysis.
What are the factors that influence the chlorophyll content in plant leaves? By using the SPAD502 chlorophyll meter to measure and analyze the chlorophyll content of plant leaves under different conditions, it was found that the chlorophyll content was affected by the following factors:
Nitrogen: This is a well-known reason, because the chlorophyll meter is used to measure the chlorophyll content of plants to guide the amount of nitrogen fertilizer. This method is widely used by users and can be achieved. Fast and convenient monitoring, while also being able to reduce the use of 10% nitrogen fertilizer without reducing production. This will not only increase profits but also reduce water and soil pollution.
Light intensity: Photosynthesis of plants is performed in the leaves of plants, and the chlorophyll content directly affects the photosynthetic rate of plants. One of the factors affecting the photosynthetic rate is the light intensity, which is measured and controlled by using the photosynthetic active radiometer. At the same time, using the SPAD502 chlorophyll meter to measure the chlorophyll, the chlorophyll content in the plant has a certain relationship with the light intensity.
