Experiments on growing sugar beet under continuous illumination

Abstract
1. Growing young sugar-beet plants under continuous illumination before transplanting into the field induced stem elongation and anthesis in considerably greater proportions than in plants not exposed to continuous light exposure.2. The technique of growing young plants under continuous light exposure during the winter offers a means of rapid multiplication of small seed stocks, and also of isolating the various physiological types comprising the population. In particular, the technique should make it possible to select types resistant to bolting.3. Analysis of the glomerule populations obtained from the plants showing anthesis at definite dates indicates that there is a definite trend in the proportions of large, medium and small glomerules as the season progresses.
