Other claims from this paper (8)

Intervention effect Low temperature accelerated PSII photoinhibition.
Intervention effect At low temperature, alpha centers declined under high light.
Observation Functional beta centers remained constant at low temperature.
Intervention effect Strong light induced less photoinhibition at room temperature.
Observation Alpha centers decreased during the first 30 minutes of high light at room temperature.
Observation PSII beta centers increased significantly at room temperature.
Mechanism The beta-center increase was attributed to migration of phosphorylated light-harvesting complex.
Observation Functional beta centers then rapidly decreased.

Other claims from this paper (7)

Association Lettuce absorbed ethylene, with absorption increasing as ethylene concentration rose.
Observation Lettuce did not absorb ethylene under dark conditions.
Intervention effect Lettuce cultivated at 0.5μL L-1 ethylene for 10 days developed epinasty and chlorosis.
Intervention effect At 0.5μL L-1 ethylene for 10 days, lettuce leaf expansion was inhibited.
Intervention effect At 0.1μL L-1 ethylene, lettuce leaf expansion was significantly inhibited.
Intervention effect Growth rate was slightly lower in ethylene exposed lettuce than in ethylene free air.
Recommendation The authors estimated the allowable ethylene level for lettuce at about 0.1μL L-1.

The Xanthophyll Cycle in Intermittent Light-Grown Pea Plants (Possible Functions of Chlorophyll a/b-Binding Proteins)

P. Jahns PLANT PHYSIOLOGY 1995. doi:10.1104/pp.108.1.149

Other claims from this paper (9)

Observation Intermittent-light plants lacked nearly all chlorophyll a/b-binding proteins.
Intervention effect De-epoxidation rates and dependence on photon flux density were similar in intermittent-light and control plants.
Intervention effect Intermittent-light plants had much higher steady-state zeaxanthin concentration than controls at any photon flux density.
Mechanism Convertible violaxanthin under illumination was interpreted as dependent on chlorophyll a/b-binding proteins.
Intervention effect Epoxidation rate differed significantly between intermittent-light and control plants.
Intervention effect Epoxidation was about fivefold slower in intermittent-light plants.
Association Epoxidation rate fell as preillumination photon flux density rose in both plant types.
Intervention effect Prolonged preillumination at high photon flux density lowered epoxidation rate in both plant types.
Mechanism The results argue against permanent xanthophyll turnover under high-light illumination.

Other claims from this paper (7)

Intervention effect Early grazing rest subsequently decreased clover population density.
Intervention effect Late rest doubled clover mass at cutting.
Intervention effect Late rest did not affect subsequent clover population density.
Association Change in clover mass under late rest depended on ryegrass variety.
Association Change in clover mass under late rest did not depend on clover variety.
Association Early rest effects on clover density were associated with shading.
Mechanism The authors attribute clover-content differences mainly to timing and less to ryegrass variety.

Claim · model-written summary

In highly compacted soil, none of the four VAM fungi produced an observable mycorrhizal growth response; authors attributed this to oxygen decline, pore changes and possible ethylene production.

“The absence of any observable mycorrhizal growth response to any of the four species of VAM fungi in highly compacted soil (bulk density = 1·75 Mg m −3 ) was attributed to the significant decrease in the O 2 content of the soil atmosphere, change in soil pore size distribution and, presumably, to ethylene production.”
