摘要：

To help ascertain the maximal productivity of plants with Crassulacean acid metabolism, measurements were undertaken on four potentially highly productive CAM species at optimal leaf or stem area indices of 4 to 6. Shoot area and shoot biomass were based on regression equations for material harvested from adjacent plants at 3-month intervals; in addition, the monitored platyopuntias were harvested to determine their dry weight at the end of the observation period. Agave mapisaga and A. salmiana near Mexico City had a productivity averaging 40 Mg ha-1 year-1 and exhibited higher maximal rates of net CO2 uptake than previously reported for CAM plants (29-34-mu-mol m-2 s-1). When irrigated and fertilized daily, Opuntia amyclea and O. ficus-indica in Saltillo, Coahuila, Mexico, had an average productivity of 46 Mg ha-1 year-1. These are among the highest productivities ever reported for any plant species.
