	Most tobaccos are day-neutral. However, there are varieties with 
other photoperiodic behaviors. Notably, Nicotiana silvestris is a long 
day plant and Nicotiana tabacum cultivar Maryland Mammoth is a short day 
plant. For more information, a good place to start is the Nicotiana 
chapter in volume 6 of the CRC Handbook of Flowering (CRC Press, Inc.)
