Other claims from this paper (10)
- Observation Leaf osmotic potential differed significantly among cultivars.
- Observation All cultivars reduced osmotic potential during the study period.
- Observation Osmotic adjustment did not vary across cultivars.
- Association Osmotic potential correlated with gas exchange in the opposite direction from expectation.
- Association Osmotic potential correlated with climate associations opposite to expectation.
- Association Cultivars associated with hotter, less humid regions had higher photosynthesis.
- Association Cultivars associated with hotter, less humid regions had higher osmotic potential.
- Observation Leaf chemical composition differed among cultivars.
- Association Leaf chemical composition was unrelated to climate associations.
- Recommendation The authors advise against selecting for more negative osmotic potential or greater adjustment to develop resilient grapes.
