Nathan Lauer University of North Florida Digital Commons (University of North Florida) 2013

Other claims from this paper (12)

Intervention effect Cypress saplings at elevated salinity had higher non-photochemical quenching.
Intervention effect Cypress leaves at elevated salinity had increased Na+, H2O2, and free proline content versus freshwater plants.
Observation Basin swamp Cypress had lower maximum quantum yield than Cypress at other sites.
Observation Basin swamp Cypress had elevated non-photochemical quenching relative to other sites.
Observation Basin swamp Cypress leaves had the highest Na+, lipid peroxidation, and proline content among sites.
Intervention effect Elevated salinity reduced detached Cypress leaf transpiration at every tested exposure time.
Intervention effect Salt stress increased total peroxidase activity after 48 hours.
Association Enhanced peroxidase activity was associated with induction of a ~37 kDa peroxidase isoform.
Intervention effect Clofibrate increased the activity of the ~37 kDa peroxidase.
Intervention effect Brefeldin A pretreatment blocked induction of the ~37 kDa peroxidase associated with salt stress.
Intervention effect Diphenyliodonium pretreatment blocked the salt stress associated decrease in Cypress leaf transpiration.

Microclimate of Grape Bunch and Sunburn of White Grape Berries: Effect on Wine Quality

Laura Rustioni; Alessio Altomare; Gvantsa Shanshiashvili; et al. Foods 2023. doi:10.3390/foods12030621

Other claims from this paper (11)

Intervention effect Canopy management did not substantially change vine vegetative-productive balance.
Intervention effect Unshaded bunches produced smaller berries with sunburn symptoms.
Intervention effect Sunburn changed the percentage distribution among berry skin, pulp and seeds.
Observation Macerated wines made from shaded grapes had significantly higher pH.
Association The higher pH was associated with lower titratable acidity.
Intervention effect Maceration increased phenolic extraction in wines.
Observation Phenolic extraction reached its maximum in wine from sunburned grapes.
Observation Absorbance at 420 nm was significantly higher in sunburned grapes.
Observation Excessive sun exposure could worsen the perceived quality of white wines without maceration through oxidative character.
Observation Sunburned grapes did not significantly affect orange or amber wine sensory quality.
Recommendation Authors recommend maceration as a possible production strategy for viticultural regions affected by climate change.
