Other claims from this paper (7)
- Intervention effect Net photosynthetic rate (PN) at saturating irradiance decreased significantly in water-stressed potato plants.
- Intervention effect Fv/Fm, relative electron transport rate and photochemical quenching declined in parallel at high irradiance under water stress.
- Intervention effect Leaf water potential declined drastically from -0.2 to -1.0 MPa in water-stressed potato leaves.
- Intervention effect Dehydrated potato leaves showed an increase in total soluble sugars per unit leaf area.
- Mechanism The authors state that the accumulated soluble sugars inhibited photosynthesis in a feedback manner.
- Intervention effect After rewatering, PN and Fv/Fm were restored to control values within 24 h.
- Association After rewatering, the restoration was accompanied by a proportionate lowering of total soluble sugar content in the leaves.
