Autecologia di Ulva rigida: 1. Influenza dell'intensità luminosa e della temperatura sulla produzione di ossigeno

Abstract Autecology of Ulva rigida C. Ag.: 1. Influence of light intensity and temperature on oxygen production. The photosynthetic activity of Ulva rigida, growing in Bari's harbour (Adriatic Sea), has been assessed in the laboratory by measuring oxygen evolution as a function of white light intensities. Tests were performed at four temperatures. The data indicate the remarkable amount of O2 released in the environment.
