Enhalus acoroides is the largest tropical seagrass species. It
is common and highly productive in coastal ecosystems. The
objective of this study was to investigate temporal growth
and reproduction of E. acoroides in Haad Chao Mai National
Park, Thailand, which is located on the eastern shore of the
Indian Ocean. Growth of E. acoroides was significantly different
among months. Average leaf elongation rate was
2.07"0.04 cm day-1 and the average leaf plastrochrone interval
was 26.1"0.6 days. New leaf production, leaf elongation
rate and leaf surface area tracked definite patterns of seasonal
change. There were two peaks of growth during the transitional
season.
