Description

Copyright © 1990 Kluwer Academic Publishers. Printed in Belgium. Manometric studies were conducted on Pterocladia capillacea, Gelidium latifolium and Gelidium spinulosum from the Azores, Portugal to determine optimal values of temperature, light and salinity for growth. Physiological responses were considered in relation to vertical distribution patterns of these species commonly observed throughout the Azores. Optimal parameters for the growth of Pterocladia capillacea, Gelidium latifolium and G. spinulosum were 17 to 25 ºC, a photon flux density between 200 and 300 umol m -2 s -1 and salinities of 25 to 35 per thousand.
