Photosynthesis rate and gas exchange measurements
Data represent means of nine samples combined from 3 d ±se. Units for photosynthesis rate are μmol CO2 fixed m−2 s−1 and the units for stomatal conductance measurements are μmol.
| Leaf Tissue | Photosynthesis | % of Wild Type | Stomatal Conductance | % of Wild Type |
|---|---|---|---|---|
| Wild type | 28.4 ± 1.3 | 100 | 0.089 ± 0.01 | 100 |
| tdy1 green | 24.3 ± 2.4 | 85.5 | 0.081 ± 0.02 | 91.0 |
