Photoperiodism is the physiological responses shown by plants depending upon the length of day and night. Long day plants have photoperiod more than 12 hours per day.  They will flower when they are exposed to the short period of darkness and the long period of light. Short day plants have photoperiod less than 12 hours per day. They require the long period of darkness and the short period of light to flower. SLDP (short-long day plant) are those plants which flower when they are exposed to the sequence of short days followed by long days.
