Induction of flowering in Tripsacum

Dear Thomas,

I don't know anything about Tripsacum, but I would make 2 suggestions:

1) Check the photoperiod (I suppose that you are using 12h ?), if it is a
short day plant, make sure that no light at all reaches the plant during the
night period (the threshold sensitivity of the photoperiodic system is just
above moonlight).

2) Could Tripsacum be a vernalization sensitive plant? If so, cold-treat the
seeds at 2-4ƒC on wet filter paper in darkness for a few weeks.

Good luck
