Claim · model-written summary
The decrease in cabbage dry weight and head yield under low light is attributed to lower sugar content and lower 14CO2 assimilation.
- Taxon
- cabbage
Brassica oleracea var. capitatat0 - Outcome
- plant dry weight and the cabbage-head yielde3
- Qualifier
- decrease in the sugar content and in the rate of 14CO2 assimilatione3
Verbatim
t0“cabbage-head formation”
e3“As the light intensity decreased, so the plant dry weight and the cabbage-head yield decreased, resulting from a decrease in the sugar content and in the rate of 14CO2 assimilation”

- Intervention effect Increasing nitrogen supply from 5 to 50 ppm N increased cabbage plant dry weight.
- Intervention effect Nitrogen supply at 500 ppm N decreased cabbage plant dry weight.
- Intervention effect Cabbage grown at 50 ppm N had the highest sugar content.
- Intervention effect Cabbage grown at 50 ppm N had the highest rate of 14CO2 assimilation.
- Mechanism Growth at 50 ppm N explains efficient cabbage-head development through the highest sugar content.
- Intervention effect Decreasing light intensity decreased cabbage plant dry weight and cabbage-head yield.
- Intervention effect Low light intensity made the 15NO3-N uptake by cabbage smaller than high light intensity.
- Intervention effect Low light impaired incorporation of 15N into the 80% ethanol-insoluble fraction of the cabbage head.
- Association The later the growth stage at which 14CO2 was assimilated, the greater the 14C-retention percentage at harvest.
- Association The later the growth stage at which 14CO2 was assimilated, the greater the distribution of 14C into the cabbage head.
- Association The 14C-retention percentage decreased with increased nitrogen supply or decreased light intensity in cabbage.
