Most of the wheat, except that in far northwest Kansas, was in the early boot to heading stages of growth at the time of the freezes. Damage can be especially severe if the freeze occurred in the late boot to flowering stages, but wheat can also be injured by a hard freeze at other growth stages.  -   Jim Shroyer     Quotes
