Vedclass · Answer

(A) In $SDP$ (Short Day Plants),the critical dark period is essential for flowering. If the dark period is interrupted by a flash of red light,the conversion of $P_{fr}$ (active form) inhibits flowering. However,if this red light flash is immediately followed by a flash of far-red light,the $P_{fr}$ is converted back to $P_r$ (inactive form),effectively nullifying the effect of the red light and allowing flowering to occur. Therefore,flowering does not occur when the dark period is interrupted by red light or a sequence that ends in red light (which maintains the $P_{fr}$ level). Option $A$ describes a condition where the final exposure is red light,which inhibits flowering in $SDP$.
