Measuring Chlorophyll Content in Plants

Chlorophyll, a pigment found in plant leaves, is responsible for converting sunlight into energy via photosynthesis. Measuring chlorophyll content is important as they are closely related to the nutritional condition of the plant. Furthermore, chlorophyll content may also be used as an indirect indicator of nitrogen levels in fertilizer to prevent over-fertilization.

Traditionally, measurement of chlorophyll is done using the wet chemical extraction method. It involves extracting plant tissues and sending it to a laboratory for analysis. This method not only damage the plant, it is also time consuming and costly. Unlike the traditional method, the use of chlorophyll meter is often preferred as it provides fast and easy measurement of chlorophyll without the need to cut off leaf samples.
