Abstract
IN Hyoscyamus niger the uracil analogue 6-azauracil has partially inhibited photoperiodic induction and caused malformations of young leaves, but these phenomena were not associated with an inhibition of stem growth. Application of pyrimidine analogues usually causes an inhibition of growth processes which involve cell division2–4 as well as cell elongation5,6. Inhibition can cause abnormal growth of the cells, thus leading to the total disorganization of the growth of the plant2. We have tried to verify this finding and to decide whether, as well as inhibition of flower differentiation in the shoot apex, there was any effect on stem growth.
