Title: Co{sub 2} exchange, environmental productivity indices, and productivity of opuntia ficus-indica under current and elevated CO{sub 2} concentrations. Carbon Dioxide Research Program

Abstract

This project involved placing mature cladodes (flattened stem segments) of Opuntia ficus-indica in growth chambers containing 360 or 720 ppM CO{sub 2}. After nine weeks, the new daughter cladodes initiated on the planted cladodes averaged 7% higher in biomass but 8% less is area, leading to a specific stem mass for this Crassulacean acid metabolism (CAM) species that was 16% higher under the elevated CO{sub 2} condition. This is similar to be less dramatic than the increase in specific leaf mass for C{sub 3} and C{sub 4} plants under elevated CO{sub 2}, which generally ranges from 28% to 40%. Another contrast with C{sub 3} and C{sub 4} Plants was the reliance of the new organs of the CAM plant on biomass translocated from existing organs instead of derived directly from current photosynthate. In this regard, 18% less dry weight was translocated from basal cladodes into daughter cladodes of Q. ficus-indica at 720 ppM CO{sub 2} compared with 360 ppM.
