内容記述 | The detemination of chlorophyll-a is important for estimating the primary production by phytoplankton, which is fundamental for detemining the material metabolism in a lake. Although extraction of chlorophyll was performed with the 90% acetone solution in the original report, we used ethanol solution because its extraction rate was higher than that of acetone. The extraction condition by ethanol was examined using the SCOR-UNESCO method. The\nconcentration of chl-a extracted under light condition was far lower than that under dark condition, and there was a signifcant difference in chl-a concentration between light and dark extraction condition after only one hour. The chl-a concentration was not different between room temperature (about 20℃) and low temperature (about 5℃) during one week under dark extracting condition. These results indicate that appropriate and convenient conditions for determination of chl-a in ethanol extraction are: 1) extracting chl-a at room temperature, and 2) determining at least with in one week. In particularly, one should keep in mind that light illumination should be minimum during the entire measurement process to avoid the decomposition of chl-a. | |||||
