Examining the extract of the cell nucleus under an electron microscope and looking for compacted chromatin would be the best way to determine if vernalization has gone on long enough for flowering to occur. Vernalization is a process that involves changes in the chromatin structure that promotes the expression of genes involved in flowering. As a result, the chromatin becomes more compact during vernalization. Therefore, if the chromatin appears compacted under the electron microscope, it would indicate that vernalization has been successful and flowering can occur.
