Other claims from this paper (11)
- Intervention effect Glyphosate lowered stomatal conductance in sugar beet exporting leaves.
- Intervention effect Glyphosate lowered carbon fixation in sugar beet exporting leaves.
- Intervention effect Glyphosate nearly completely inhibited allocation of fixed carbon to foliar starch.
- Intervention effect Lowering CO2 in untreated leaves decreased starch accumulation in proportion to net carbon fixation.
- Intervention effect Shikimate level increased 50 fold in treated sugar beet leaves.
- Association Increased shikimate carbon accumulation accounted for only 4% of decreased starch accumulation rate.
- Observation No other major daytime differences in labeled amino acids or compounds were found between treated and control leaves.
- Mechanism Less labeled carbon accumulated in treated leaves because fixation decreased.
- Observation Carbon export was maintained at the level of control leaves.
- Intervention effect Restoring net carbon exchange fully restored starch accumulation.
- Intervention effect Restoring net carbon exchange prevented a decline in export during the following dark period.
