Claim · model-written summary
Deficit irrigation reduced fruit yield, fruit size and fruit count of glasshouse tomatoes.
Solanum lycopersicumVerbatim
e0“In glasshouse-grown tomatoes ( Lycopersicon esculentum Mill. `Virosa'), deficit irrigation (DI), in which plant water potential was allowed to decrease from –0.5 to –1.2 MPa, reduced plant growth and fruit yield, size and count, and caused blossom-end rot”
e1“Deficit-irrigated fruit had higher color intensity, lower water content, and higher concentration of sucrose, glucose, and fructose than well-watered (control) fruit”

Other claims from this paper (11)
- Intervention effect Deficit irrigation reduced plant growth of glasshouse tomatoes.
- Intervention effect Deficit irrigation caused blossom-end rot in glasshouse tomatoes.
- Intervention effect Deficit-irrigated tomato fruit had higher color intensity than well-watered control fruit.
- Intervention effect Deficit-irrigated tomato fruit had lower water content than well-watered control fruit.
- Intervention effect Deficit-irrigated tomato fruit had higher concentrations of sucrose, glucose and fructose than well-watered control fruit.
- Intervention effect Ca, Mg and K concentrations of tomato fruit were the same under both treatments on a dry weight basis.
- Intervention effect Ca, Mg and K concentrations were higher in deficit-irrigated tomato fruit than in control fruit on a fresh weight basis.
- Intervention effect Deficit-irrigated tomato fruit produced higher quantities of CO 2 and ethylene than control fruit for both harvests.
- Observation Ethylene and CO 2 production peaks coincided for the first harvest in both treatments of tomato fruit.
- Observation In the second harvest, the CO 2 production peak of tomato fruit preceded that of ethylene.
- Intervention effect Deficit irrigation enhanced tomato fruit desirability despite yield reduction.
