Dividing Cells as the Locus for Vernalization

Abstract

IN an earlier communication1 I described the “leaf vernalization” of leaf cuttings of Lunaria biennis. After cold treatment, such cuttings from leaves of adult plants regenerate and yield flowering plants, while without a cold treatment no flowering occurs. It was left undecided exactly where in the leaf cutting the vernalization takes place—in the leaf as a whole or in meristematic cells only. Evidence has been obtained now that the locus of vernalization consists of cells which are in the process of mitosis.
