Short Day Plants (SDP)

• These plants require a relatively short day light period (usually 8-10 hours) and a continuous dark period of about 14-16 hours for subsequent flowering. Some examples of these plants which are also known as long-night-plants are Maryland Mammoth variety of tobacco (Nicotiana tabacum), Biloxi variety of Soybeans (Glycine max) and Cocklebur (Xanthium pennsylvanicum).
