Step-by-step solution

Short-day plants require a continuous and uninterrupted dark period exceeding a critical duration to initiate flowering.
If the dark period is interrupted even by a brief flash of light, the phytochrome system is reset, which inhibits the flowering process.
Therefore, these plants will not flower.
