e0“The top fresh weight of spinach under high (100 μmolm-2s-1) and low (10 μmolm-2s-1) light intensities was approximately 3 to 5 times higher than the control (no lighting)”
e3“accompanied with inhibition of flower bud development under the mid-night lighting at high light irradiance treatment”

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 IAA content in spinach under high light irradiance was about twice that under low light irradiance or control.
- Intervention effect Applications of IAA and IAA inhibitors had no clear effect on flower bud development and bolting in spinach.
- 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.
