Vedclass · Answer

(B) Short-day plants $(SDP)$ require a photoperiod shorter than a critical duration to flower.Additionally,they require a long,continuous,and uninterrupted dark period (night) to trigger the flowering response.If the dark period is interrupted by even a brief flash of light,the flowering process is inhibited.Therefore,the correct condition is a photoperiod shorter than the critical length and a long uninterrupted night.
