Intervention effect Grain yield fell significantly by 15 to 73% across heat treatments.

Other claims from this paper (13)

Observation Field-dried shoots remained viable and elongated during recovery, but did not attain control activity.
Observation Field-dried shoots shifted hue after recovery but did not match controls.
Observation Field-dried shoots regained positive net photosynthesis after recovery, below controls.
Observation Saturated shoots had moisture content of 1296.4% by weight.
Intervention effect IRGA caused about 40% moisture loss from initially moist shoots.
Observation Control shoot moisture declined about 40% during IRGA and then gradually in recovery.
Observation Control shoot net carbon gain declined over the study.
Intervention effect Dried shoot moisture content fell an order of magnitude across treatments.
Observation Dried shoot moisture returned near control levels after recovery.
Intervention effect Drying reduced net photosynthesis to zero.
Observation Net photosynthesis did not resume after rehydration.
Mechanism The authors suggest field drying is less severe or prolonged than laboratory drying.
Mechanism The authors suggest colony form shields inner shoots from severe exposure.

Intervention effect Ground cover decreased vine net photosynthesis relative to soil tilling.
Observation Tall fescue had the lowest net photosynthesis in both years.
Observation Soil tilling had the highest net photosynthesis in both years.
Mechanism The reduction in photosynthesis was interpreted as regulated by a non-stomatal mechanism.
Intervention effect Grass-covered plots reduced pruning material weight, shoot growth and leaf area per vine in both years.
Intervention effect Groundcover reduced vine yields, especially Tall fescue.
Intervention effect Groundcover lowered cluster number.
Intervention effect Groundcover lowered cluster weight.
Intervention effect All grass covers reduced time between veraison and harvest, especially fescue.
Recommendation Groundcover was proposed for dry areas to improve berry quality and harvest date.

Salinity Effects on Photosynthesis in Isolated Mesophyll Cells of Cowpea Leaves

Other claims from this paper (10)

Association CO2 fixation was maximal when isolation and assay osmotic potentials approached leaf osmotic potential.
Intervention effect Hypotonic and hypertonic media reduced photosynthesis regardless of growth salinity.
Intervention effect At 130 moles per cubic meter NaCl, photosynthesis fell only 30% under optimal assay conditions.
Observation Photosynthetic inhibition was reversible when saline stress was relieved.
Intervention effect At 173 moles per cubic meter NaCl, photosynthesis was severely and irreversibly inhibited.
Mechanism The severe photosynthetic inhibition was attributed to leaf chloride and sodium accumulation.
Observation Sorbitol uptake by intact cells was insignificant.
Association Sorbitol uptake was not associated with cell volume changes.
Observation Cells from low salinity grown plants had a light response curve similar to controls.
Intervention effect Cells grown at 173 moles per cubic meter NaCl reached light saturation at lower radiant flux density than lower salinity cells.
