Chlorophyll meter: Quantitative determination of plant chlorophyll

Jan 03, 2019

Why measure the chlorophyll content of plants? Because chlorophyll is the main pigment for photosynthesis in plants, its content has a significant effect on the photosynthesis of plants, and the content of chlorophyll is closely related to plant nitrogen nutrition. By measuring the chlorophyll content of plants, plant nutrition can also be understood. The status and crop utilization of nitrogen in the soil, etc., therefore the determination of plant chlorophyll content is a basic scientific research project in scientific fertilization, breeding and plant pathology research. In the field of modern agricultural research, in order to achieve quantitative determination of plant chlorophyll, a chlorophyll meter can be used.


Chlorophyll is a kind of fat-containing pigment, which is located in the thylakoid membrane. It plays a central role in the light absorption of photosynthesis. Without chlorophyll, plants can not carry out photosynthesis, and the chlorophyll content is insufficient, then the photosynthesis of plants is also Will be affected. Therefore, with the deepening of scientific research, the demand for quantitative determination of plant chlorophyll is getting higher and higher. To quantify the chlorophyll content, it can be quite complicated if it is done in the usual way, but it is very simple to use the chlorophyll meter. The instrument has the characteristics of simple operation, high detection speed, high precision, time and labor saving, cost saving and portability. The application of the instrument provides a new and efficient measurement method for the quantitative determination of plant chlorophyll.


Since chlorophyll absorbs most of the red and violet light, but reflects green light, the leaves will appear green. It is precisely because of this that people have long been observing the nutrient status of plants by observing the leaf color of plants, but as the degree of refinement of agriculture continues to increase, this rough judgment method has been difficult to meet scientific research and production guidance work. The need for chlorophyll analyzers to achieve quantitative determination of plant chlorophyll has become more widespread.


       At present, the chlorophyll analyzer, which combines image acquisition, pretreatment, segmentation, analysis, and chlorophyll into a quantitative measurement of plant chlorophyll, has played an important role in practical applications, and has continuously improved the efficiency of scientific research. Greatly improved the scientific research results and promoted the development of scientific agriculture.
