Pain, at least in animals, has been defined as an aversive sensory
response and associated emotional experience, which elicits 
protective motor responses and learned behavior. That is to say,
pain perception has probably evolved as a protective means by
which the individual can avoid injurious stimuli. Since plants
have no means to avoid such stimuli (eg. motor and behavioral
responses), I can think of no evolutionary advantage to plants
developing pain perception. Of course, someone with more knowledge
of plant biology may be able to provide a better answer.
