Fijación de CO2, en Agave angustifolia Haw.

The anatomical-morphological and physiological adaptations present in CAM plants like agaves make them more water use efficient and able to growth and produce under restrictive environmental conditions. We report on a field trial C02 uptake by Agave angustifolia Haw. of four and eight years of age, undertaken in Matatlán, Tlacolula, Oaxaca. The maximum and minimum estimated C02 uptakes rates were 30, 29; 1, 2 μmol m-2 s-1 and occurred in October and November of 1993, for the four and eight years plants; 30 and 29 μmol m-2 s-1 can be considered high when compared with estimated figures for other agave species studied previously.
