Abstract
A PREVIOUS letter in NATURE1 presented evidence to show that in winter rye (var. Petkus) anaerobic conditions at normal temperatures (20° C.) when alternated with aerobic conditions at 1° C. quantitatively annul the vernalizing effect of low temperature. It appeared possible, therefore, that spring rye of the same variety might be devernalized by the application of anaerobic treatment at 20° C. Previous work2,3 has shown that the process of vernalization in winter rye decreases the number of leaves produced on the main axis before flower initiation, as well as decreasing the period of time required to reach anthesis. An increase in these characteristics in spring rye after anaerobic treatment would thus indicate a process of devernalization.
