e0“Compared to pre-flowering LR, LR applied at the flowering stage decreased acidity and yeast assimilable nitrogen concentrations, increased the concentration of the aroma precursor Cys-3MH in the must at harvest, and slightly enhanced the overall quality of the white wine.”

- Intervention effect Pre-flowering leaf removal reduced harvest yield.
- Intervention effect Pre-flowering leaf removal decreased berries per cluster.
- Association Cold and low light before flowering significantly influenced fruit set and amplified yield losses from early leaf removal.
- Association Cold and low light amplified yield loss from pre-flowering leaf removal.
- Intervention effect Moving leaf removal to flowering helped manage yield loss.
- Intervention effect Flowering-stage leaf removal decreased acidity.
- Intervention effect Flowering-stage leaf removal decreased yeast assimilable nitrogen.

- Intervention effect Increasing trimming height increased the leaf-to-fruit ratio.
- Intervention effect Increasing trimming height improved grape ripeness at harvest.
- Intervention effect Increasing trimming height raised TSS.
- Intervention effect Increasing trimming height lowered tartaric acid.
- Intervention effect Increasing trimming height improved wine colour, floral character and volume.
- Intervention effect Increasing trimming height improved overall wine impression.
- Recommendation The flowering-stage removal plus taller canopy combination appeared to mitigate yield loss.
- Recommendation The flowering-stage removal plus taller canopy combination appeared to improve must Cys-3MH composition.
