Long Day Plants (LDP) require a photoperiod of more than a critical length, ie, 4 to 18 hours. The best flowering of long day plants usually occurs in continuous light. For flowering, they require either no dark period or a very short dark period. Example of long day plants are wheat, maize, oats, spinach etc.
