Title

Changes in net photosynthetic rate and chlorophyll fluorescence in potato leaves induced by water stress

P.S. Basu; Ashoo Sharma; N.P. Sukumaran Photosynthetica 1998. doi:10.1023/a:1006801311105

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.

Title

Influence of drought hardening on the resistance physiology of potato seedlings under drought stress

Shu-han ZHANG; Xue-feng XU; Ye-min SUN; et al. Journal of Integrative Agriculture 2018. doi:10.1016/s2095-3119(17)61758-1

Other claims from this paper (11)

Intervention effect Drought hardening inhibited increases in relative electric conductivity and malondialdehyde content.
Intervention effect Drought-hardened seedlings had enhanced root vigor under drought.
Intervention effect Drought-hardened seedlings had increased antioxidant enzyme activity.
Intervention effect Drought-hardened seedlings had higher abscisic acid, proline and soluble sugars under drought.
Intervention effect Drought-hardened seedlings had higher polyamine levels under drought.
Intervention effect Stomatal density increased significantly with drought hardening.
Intervention effect Leaf area, stomatal size and stomatal aperture decreased with drought hardening.
Observation The changes reduced leaf transpiration rate.
Observation The changes improved water utilization efficiency.
Mechanism Leaf microstructure changes had a positive effect on drought resistance.
Mechanism Authors attribute enhanced resistance physiology to increased hormones, osmotic substances and antioxidant enzyme activity.
