摘要
Unialgal isolates of Gelidium latifolium from northern Spain and western Norway were compared with respect to specific growth rate, when kept under different combinations of light (20, 50, 100, 200, 300 mumol m-2s-1) and temperature (17, 20, 24, 28, 31-degrees-C). The Norwegian isolate grew almost twice as fast as the Spanish isolate under all combinations tested. Maximum growth rate for the Norwegian and Spanish isolates was 6.71 % d-1 and 3.64 % d-1, respectively. The results show the existence of ecotypes and the importance of inoculum selection in the development of a mass cultivation system for Gelidium.
