Vedclass · Answer

(C) It has been demonstrated that flowering in plants is more of a response to the dark period than to the light period.In short-day plants $(SDP)$,the plants can flower in complete darkness if supplied with exogenous nutrients.Flowering is inhibited in $SDP$ if the dark period,which is essential for flowering,is interrupted by a flash of light.Therefore,the Reason is incorrect because a light break during the dark period prevents flowering in short-day plants,rather than inducing it.

Assertion: Dark period plays a more important part in flowering than the light period.
Reason: Flowering occurs in short-day plants if the dark period is interrupted by a light break.
