Other claims from this paper (10)
- Observation Tall fescue had the lowest net photosynthesis in both years.
- Observation Soil tilling had the highest net photosynthesis in both years.
- Observation The decrease in photosynthesis did not have a corresponding decrease in transpiration rate.
- Mechanism The reduction in photosynthesis was interpreted as regulated by a non-stomatal mechanism.
- Intervention effect Grass-covered plots reduced pruning material weight, shoot growth and leaf area per vine in both years.
- Intervention effect Groundcover reduced vine yields, especially Tall fescue.
- Intervention effect Groundcover lowered cluster number.
- Intervention effect Groundcover lowered cluster weight.
- Intervention effect All grass covers reduced time between veraison and harvest, especially fescue.
- Recommendation Groundcover was proposed for dry areas to improve berry quality and harvest date.
