Abstract

Anatomy Structure and Chlorophyll Content of Enhalus acoroides from East Bintan Coastal and Dompak Island, Riau Islands. Seagrasses able to adapt to differences in water quality in their habitat. The differences in water quality can be caused by several factors, such as an impact of anthropogenic activities and natural habitat conditions such as substrate types, currents, and waves. Differences in water quality can provide different physiological responses such as anatomical structure and chlorophyll content. The purpose of this study was to compare the chlorophyll content and the size of the anatomical structure of the tissue in Enhalus acoroides to the water conditions on the east coast of Bintan and Dompak Island. This research was conducted from February to March 2021 in Berakit waters, Teluk Bakau, and Dompak. Determination of sample points was based on purposive sampling method. Water quality data was taken directly at the location. Chlorophyll content, tissue anatomy, total organic matter, and turbidity were measured in the laboratory. Seagrasses in Berakit waters generally have a thicker anatomical structure of leaf tissue than other locations. In contrast, the anatomical structure of rhizoma tissue, which has a large thickness, is found at Teluk Bakau and Dompak stations. The highest chlorophyll content was found in Berakit waters at 16.554 mg/L (chlorophyll-a), 6.141 mg/L (chlorophyll-b) and the lowest was in Dompak waters 13.183 mg/L (chlorophyll-a), 3.723 mg/L (chlorophyll-b). The condition of the water parameters can affect the anatomical structure and chlorophyll content of E. acoroides.
