Variation in Quantum Yield for CO2 Uptake among C3 and C4 Plants
Open accessAbstract
The quantum yield for CO(2) uptake was measured on a number of C(3) and C(4) monocot and dicot species. Under normal atmospheric conditions (330 microliters per liter CO(2), 21% O(2)) and a leaf temperature of 30 degrees C, the average quantum yields (moles CO(2) per einstein) were as follows: 0.052 for C(3) dicots, 0.053 for C(3) grasses, 0.053 for NAD-malic enzyme type C(4) dicots, 0.060 for NAD-malic enzyme type C(4) grasses, 0.064 for phosphoenolpyruvate carboxykinase type C(4) grasses, 0.061 for NADP-malic enzyme C(4) dicots, and 0.065 for NADP-malic enzyme type C(4) grasses. The quantum yield under normal atmospheric conditions was temperature dependent in C(3) species, but apparently not in C(4) species. Light and temperature conditions during growth appeared not to influence quantum yield. The significance of variation in the quantum yields of C(4) plants was discussed in terms of CO(2) leakage from the bundle sheath cells and suberization of apoplastic regions of the bundle sheath cells.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
