changing lighting on seedlings

HI All--Somewhere I got the idea that seedlings can be kept growing under 24/7 lighting for a considerable period of time and they will not be negatively affected.  However, once the seedlings are taken off the 24/7 routine and are placed on a more "natural" lighting cycle they must stay on the "natural" cycle and be given a number of hours of darkness.  If they are put back on 24/7 lighting, the plants are unable to adapt.  Is this true?   Any information about this would be appreciated.
