Abstract: This study showed that as compared with the control, a short term continuously diurnal desiccation promoted the growth of Ulva pertusa, manifesting in the increase of specific growth rate (SGR) and chlorophyll a content. However, with the prolonged desiccation duration, the SGR and chlorophyll a and protein contents decreased, while the chlorophyll b and soluble sugar contents increased. The changes of chlorophyll a/b and soluble sugar content could benefit the desiccation tolerance of U. pertusa.
