Abstract

Effective and Maximum quantum yield is important in assessing the photosynthetic ability of the lace coral Pocillopora damicornis. The changes of its photosynthetic ability can reflect its current health status. A pulse amplitude modulation (PAM) chlorophyll fluorescence technique was used and measurements were taken in situ and in real time using a submersible PAM fluorometer or Diving-PAM. Two colonies of P. damicornis were chosen and their effective quantum yield (light-adapted) (δF/Fm was measured for 21 days with an average yield value of 0.70±0.05 and 0.72+0.03 for colony 1 and 2 respectively. Maximum quantum yield (dark-adapted) (F v/Fm reading was taken at dawn between 06:00-07:00 hour with an average yield value of 0.70±0.02 for each colony. The diurnal variation showed that P. damicornis was most vulnerable during noontime. Under 'normal' conditions, the light and dark adapted corals gave almost similar yield values. This information could be used as the baseline standard of P. damicornis yield value in its 'normal' state in Pulau Tioman and generally for the east coast of Peninsular Malaysia.
