A PHYSIOLOGICAL TEST OF THE THEORY OF COMPLEMENTARY CHROMATIC ADAPTATION. I. COLOR MUTANTS OF A RED SEAWEED1

摘要: The physiological behavior of phycoerythrin-deficient mutants the red seaweed Gracilaria tikvahiae (Mc-Lachlan 1979) is compared to that their wild types. are phenotypically green while types red. Cloned scions were grown factorially at irradiances saturating and limiting growth, spectral distributions which broadband (white) narrowband (green). light field complements absorptance spectrum phycoerythrin. Experiments performed in an outdoor continuous flow system. Physiological measurements included light-harvesting pigment composition, instantaneous photosynthesis-light relationships growth. In all cases, as type progenitors. Further, responses occurring no less than 8 days dependent solely on irradiance (“intensity”), independent distribution (“color”). data do not conform with predictions theory complementary chromatic adaptation for seaweeds.
