Other claims from this paper (13)
- Intervention effect Dark-treated green-gram plants had markedly smaller final plant weight and leaf area than untreated plants.
- Intervention effect Growth trends in dry weight and leaf area of dark-treated plants were similar to those of untreated plants.
- Intervention effect In earlier stages, net assimilation rate was much higher in dark-treated series than in untreated series.
- Intervention effect Leaf area ratio of dark-treated plants was smaller in all plots in earlier stages.
- Intervention effect Relative growth rate was scarcely affected by dark treatment.
- Observation In later stages, no difference in NAR, LAR or RGR was observed between the two series.
- Intervention effect Initial three-day RGR of DN-100 plants was low (0.14 mg/mg/day) compared with 0.23 mg/mg/day for N-100.
- Mechanism Low RGR may bring about the low final plant weight of DN- and DO-plants.
- Association Leaf area/leaf weight ratio of DN- and DO-plants increased markedly with decreasing illumination.
- Intervention effect Leaf area/leaf weight ratio of DN- and DO-plants gave nearly identical results to untreated plants.
- Observation C/F ratio of untreated N- and O-plants was maintained at 1.0-1.5 throughout the experiment.
- Intervention effect After placement in full daylight, C/F ratio of DN- and DO-plants dropped rapidly from 7-8 and then slowly approached 1.0.
- Mechanism High C/F ratio should be largely responsible for the low RGR in the initial days after the dark period.
