Intervention effect The critical Mg content causing a 50% decrease in cabbage-head yield was 0.15%.
Intervention effect The critical S content causing a 50% decrease in cabbage-head yield was 0.04%.
Intervention effect A longer period of nutrient supply gave higher cabbage-head yield.

Other claims from this paper (9)

Observation The three species differed widely in light-saturated CO2 uptake capacity.
Observation The species reached CO2 uptake light saturation at different photon flux densities.
Observation Nonphotochemical quenching occurred below CO2 uptake saturation without zeaxanthin.
Observation Nonphotochemical quenching increased to 0.35–0.5.
Observation Nonphotochemical quenching increased again near CO2 uptake saturation.
Observation Leaf zeaxanthin content rose near CO2 uptake saturation.
Observation Instantaneous fluorescence yield began decreasing near CO2 uptake saturation.
Association Increasing zeaxanthin paralleled increasing radiationless energy dissipation.
Association The authors suggest zeaxanthin may relate to high-energy-state quenching.

Other claims from this paper (12)

Intervention effect Hedging did not influence yield in 1985.
Intervention effect Increasing hedging severity reduced yield linearly in 1986 and 1987.
Intervention effect Delaying hedging reduced yield to some degree.
Observation Ten-leaf and postbloom hedging affected cluster number least.
Intervention effect Greater hedging severity linearly reduced cluster weight and berries per cluster.
Observation Berry weight was highest with the least severe hedging at full canopy development.
Intervention effect More severe hedging reduced soluble solids and total anthocyanins in 1985 and 1987.
Observation The severity trend for soluble solids and anthocyanins reversed in 1986.
Intervention effect Delaying hedging linearly decreased soluble solids and anthocyanins in 1985.
Association In 1985, higher pH was associated with less severe and later hedging.
Observation Unhedged controls were generally at least equal to hedged vines on many yield and fruit composition measures.
Observation Significant undesirable responses were generally confined to five-leaf severity at full canopy or veraison timing.

Other claims from this paper (11)

Observation First trifoliate leaf growth rose shortly after light began.
Observation Leaf turgor decreased slightly around the start of light.
Observation Cell wall plasticity increased around the start of light.
Mechanism Declining turgor may explain declining leaf growth through the light period.
Intervention effect Restricted water supply slightly enhanced dark growth rates relative to well supplied plants.
Intervention effect Restricted water supply significantly reduced light growth rates relative to well supplied plants.
Observation Leaf turgor was similar between water supply groups in light.
Mechanism Reduced growth of cooled plants may result from changed cell wall properties.
Observation Restricted water supply plants had relatively high trifoliate turgor before lights came on.
Mechanism High prelight turgor presumably explained enhanced growth at that time.
Intervention effect Restricted water availability may slightly increase cell wall plasticity.
