Other claims from this paper (8)
- Association Rate of tomato fruit growth was positively correlated with soil water content on both sides of the soil-drying treatment and the dry side of partial root-drying.
- Intervention effect Soil drying significantly restricted tomato fruit growth rate, independently of changes in mesocarp cell turgor.
- Intervention effect Supplying water to half of the root system maintained fruit mesocarp cell turgor above well-watered control values.
- Intervention effect Leaf epidermal cell turgor showed a response similar to that of fruit mesocarp cells when half the root system was watered.
- Intervention effect Soil drying increased sub-epidermal apoplastic pH in tomato leaves and fruit.
- Association Fruit growth rate and sub-epidermal pH within the tomato fruit were strongly and positively correlated.
- Mechanism A non-hydraulic, chemical-based signalling control of fruit growth is proposed for tomato plants in drying soil.
- Observation Tomato plants respond to a discrete measure of soil water status rather than integrating total soil water availability.
