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 Relations of RGR, NAR and LAR to varying light intensity showed similar trends in dark-treated and 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.

Other claims from this paper (11)

Intervention effect Spinach under high mid-night lighting (100 μmolm-2s-1) had top fresh weight about 3 to 5 times that of the unlit control.
Intervention effect Spinach under low mid-night lighting (10 μmolm-2s-1) had top fresh weight about 3 to 5 times that of the unlit control.
Intervention effect Mid-night lighting induced bolting in spinach.
Intervention effect High light irradiance delayed bolting in spinach compared with low light irradiance.
Intervention effect High light irradiance mid-night lighting inhibited flower bud development in spinach.
Intervention effect IAA content in spinach under high light irradiance was about twice that under low light irradiance or control.
Intervention effect Gibberellin A3 rapidly induced bolting in spinach under all treatments.
Intervention effect Prohexadione-calcium or uniconazole applications delayed bolting in spinach under mid-night lighting.
Intervention effect GA20 and GA1 levels in spinach were about 80% higher under low light irradiance than under high light irradiance.
Mechanism High light irradiance of mid-night lighting appears to inhibit gibberellin biosynthesis in spinach.
Mechanism A relatively lower GA level under high light irradiance may retard bolting and flowering in spinach.
