Stomatal conductance of maize under water and nitrogen deficits
Open accessAbstract
The objective of this work was to evaluate the effect of drought and nitrogen (N) stresses on stomatal conductance of three maize cultivars grown in the field. The stomatal conductance of Sol da Manhã variety (BRS 4157) and Pioneer 6875 hybrid, under drought and high N, was lower than under drought and low N, which indicates drought tolerance, since these cultivars did not exhibit reduction in grain yield by drought, as observed for Amarelão variety, which flowered under more severe drought. 'Sol da Manhã' exhibited shorter anthesis-silking interval under high N than under low N, an additional indication of tolerance.

Stomatal conductance was on the lower end of the range previously observed for maize (<100 mmol m-2 s-1 under drought and 100-200 under fully irrigated), with the same trend of lower stomatal conductance under water stress.
“Stomatal conductance was on the lower end of the range previously observed for maize b100 mmol m -2 s -1 under drought conditions and 100-200 mmol m -2 s -1 under fully irrigated conditions (Medici et al., 2007), with the same trend of lower stomatal conductance under water stress (Supplementary Fig. 4).”

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.
