摘要: Photosynthetic performance was measured on site in four common Atlantic green algae, Asparagopsis taxiforme, Valonia utricularia, Caulerpa racemosa and Codium taylori, Gran Canaria, Canary Islands. The photosynthetic quantum yield determined with a portable PAM instrument diving the water column. Solar radiation continuously above column by means of two three-channel dosimeters, ELDONET (Real Time Computer, Mohrendorf, Germany), UV-A, UV-B PAR ranges. effective found to be affected exposure solar as short 15 min but recovered shade most species within several hours. Only A. taxiforme failed recover completely, 30-min caused severe photoinhibition from which algae only partially. While effect due wavelength range, UV, especially UV-B, range considerably enhanced photoinhibition. In all species, significant inhibition even at their growth sites column, PAM, high angles.
