Which potted plant will show flowering after exposure to light?

Filo · Accepted Answer

A short day plant (SDP), which has a critical period of 14 hours, will flower only if it is provided a continuous period of darkness of 14 hours; which has been given to the potted plant-I only. In rest of the potted plants, more amounts of light periods are being given and thus the dark periods have been reduced to below 14 hours.
