(N/A) The flowering in short-day plants is not primarily controlled by the length of the light period,but rather by the length of the dark period.
These plants require a continuous and uninterrupted dark period that exceeds a certain critical duration to initiate the flowering process.
If this long dark period is interrupted by even a brief flash of light,the plants fail to flower.
Therefore,it is scientifically more accurate to refer to them as long-night plants.
