Other claims from this paper (8)
- Intervention effect Ascorbate free radical stimulated glucose, fucose, sucrose and nitrate uptake.
- Intervention effect Glucose and fucose uptake became linear with time after treatment, versus saturation kinetics in untreated roots.
- Intervention effect Nitrate and sucrose uptake rates increased after treatment while kinetics resembled controls.
- Intervention effect Ascorbate inhibited nutrient uptake.
- Intervention effect Dehydroascorbate inhibited nutrient uptake.
- Intervention effect Uptake rates for all nutrients increased throughout 48 hours of pretreatment.
- Intervention effect Vacuole volume and tonoplast surface area increased during treatment.
- Association Stimulated uptake and increased vacuolar volume were associated with enhanced root elongation.
