Physiological performance and growth under low and high light treatments in three neotropical species of Cecropia
Light acclimation in gas exchange properties was found in three different Neotropical species of Cecropia under greenhouse conditions. Two species are habitat specialists (C. tessmannii, a shade species and C. membranacea, a sun species), and the third ís a generalist (C. pachystachya). The shade species showed the least flexibility. Rates of photosynthesis were positively correlated with light intensify, transpiration and conductance. Photosynthetic rates for each species ranked in the same order as growth rates. The generalist species, C. pachystachya performed, oil average, better than any of the specialists in their own light environment.

Tres especies de Cecropia mostraron aclimatación lumínica en parámetros asociados a fotosíntesis medidos en condiciones de vivero. Dos de estas especies son especialistas respecto del recurso luz (C. tessmannii, de sombra, y C. membranacea, de sol), mientras que la tercera, C. pachystachya, es generalista. La especie de sombra fue la que mostró menor flexibilidad en los parámetros medidos. La tasa fotosintética varió positivamente con la intensidad lumínica, transpiración .y conductancia. El orden relativo de las tasas fotosintéticas y de crecimiento file el mismo para coda una de las tres especies siendo la especie generalista la que presentó los mayores valores.
