Photosynthetic activity, photoinhibition and recovery of photosynthesis in the brown alga Adenocystis ultricularis and in the red alga Palmaria decipiens were studied infield experiments on King George Island (Antarctica) in February 1993. Experiments were carried out with a portable fluorometer ...
La actividad fotosintética, la fotoinhibición y la recuperación de fotosíntesis en el alga café Adenocystis utricularis y en el alga roja Palmaria decipiens se estudiaron en experimentos de terreno en isla Rey Jorge, Antártica, en febrero de 1993. Los experimentos se llevaron a cabo con un fluoró...
Photosynthesis at high latitudes demands efficient strategies of light utilization
to maintain algal fitness and performance. The fitness, and physiological
adaptation, of a plant or algae species depends in part on the abundance and
efficiency of the pigments it can produce to utilize the light ...
La energía solar es potencialmente dañina para plantas cuando excede su capacidad fotosintética. Las plantas pueden protegerse de este daño, mediante mecanismos de disipación del exceso de energía, en el que participan pigmentos del grupo de las xantofilas (carotenoides oxígenados). Deschampsia a...
The sun energy can be potentially harmful when exceeds the photosynthetic capacity of plants. There are photoprotective mechanisms that permit the dissipation of the excess of energy absorbed by plants, being one of this mechanism associated with pigments of the xanthophyll (oxygenated carotenoid...
