Jayasankar, Reeta and Kulandaivelu, G (2000) Effect of Light Intensities on the Fluorescent Yield of Gracilaria spp. In: The Fifth Indian Fisheries Forum, 17-20 January, 2000, Bhubaneswar, Orissa.
The fluorescent kinetics of Gracilaria spp. showed variation among different species when subjected to varying treatment of light intensities. In control (untreated fresh sample), the variable fluorescence and the quantum yield was maximum in G. corricara than G. eddis and G. crassa. Upon exposure to different treatments for 12 days, it was observed that the values of fluorescent yield increascd in all treated samples of G. edulis and such increase was maximum only in the sample kept under intermediate light (2.0 w/m2). In G. crassa, the variable fluorescence and the quantum yield increased under intermediate light. Further treatment resulted in decline of the above value under high light (3.0 w/m2) and intermediate light intensities. In G. corticata, the Fv and the Fv/Fm values declined within 6 days of treatment but marginal recovery occurred on 12th day of treatment.
