Tobacco plants produce flowers in the following conditions EXCEPT:

Step-by-step solution

Tobacco is a short-day plant (SDP), which requires a continuous, uninterrupted dark period exceeding a critical duration to initiate flowering. A long uninterrupted dark period or a short light period followed by a long uninterrupted dark period will induce flowering in tobacco. If a long dark period is interrupted by a flash of red light, flowering is inhibited. However, if the red light is immediately followed by far-red light, the inhibitory effect is reversed, and the plant will flower. A long uninterrupted lig
