Other claims from this paper (10)
- Intervention effect Rainfed plants accumulated less above-ground dry mass than irrigated controls.
- Intervention effect Rainfed plants had lower gas exchange, leaf water potential and intercepted radiation.
- Intervention effect Rainfed leaves had higher ion and protein concentrations.
- Intervention effect Fruit ion accumulation did not change between treatments.
- Association The PSI–PSII quantum-yield correlation was similar under irrigation and rainfed conditions, even under severe stress.
- Mechanism Moderate field stress limited photosynthesis mainly through lower stomatal conductance.
- Mechanism Under severe rainfed stress, reduced mesophyll conductance also impaired photosynthesis.
- Mechanism Photosynthetic limitation reduced plant growth, fruit yield and marketability.
- Recommendation The authors concluded irrigation is necessary for optimal bell pepper production.
- Recommendation The authors proposed deficit irrigation may delay gas exchange and growth decline as soil dries.
