Vedclass · Answer

(D) The plants that flower when exposed to a $12$ hour day and $12$ hour night cycle,but fail to flower when the night is interrupted by a brief period of light,are classified as Short-day plants $(SDP)$.Short-day plants require a continuous,uninterrupted dark period of a specific critical length to initiate flowering.When the dark period is interrupted by light,the physiological signal for flowering is inhibited,preventing the plants from flowering.Therefore,these plants are Short-day plants.

$A$ group of plants flowered when exposed to a $12$ hour day and $12$ hour night cycle. Another group of the same plants did not flower when exposed to the same day-night cycle but with a brief light interruption during the night. What type of plants are these?
