e0“A decrease of stomatal conductance and, consequently, of the photosynthetic rate, transpiration and water use efficiency was observed already at low severity level with increments of the disease severity on the leaf.”

Other claims from this paper (7)
- Observation Sporulating regions of diseased grapevine leaves had drastically reduced photosynthetic rate.
- Observation Stomatal and mesophyll conductance decreased in diseased grapevine leaves.
- Observation Stomatal resistance increased in diseased grapevine leaves.
- Observation Downy mildew had a more negative effect on symptomless lateral leaf gas exchange than on main leaves.
- Association At low disease severity, stomatal conductance, photosynthesis and transpiration decreased in symptomless grapevine lateral leaves.
- Observation Stomatal resistance increased in symptomless areas of lateral grapevine leaves.
- Method / resource Visual estimates of downy mildew area understated latent lesions in apparently healthy leaf regions.
