vernalize

However, this stable silenced or 'vernalized' state must be reset in each generation.

Mayberry, now retired in Colorado, went on to cross Imperial Star with varieties he found in Peru and developed the first vernalized purple artichoke variety, Colorado Star.

We vernalize artichokes, which survive winter in moderate climates and, as biennials, bear the second year.

These findings suggest that resetting the vernalized state is a process of de novo FLC activation in the pro-embryo by an embryonic transcription factor and occurs regardless of whether parental plants have been vernalized.

This process, known as vernalizing, was pioneered at a number of research stations, including one at Virginia Tech.
