Summary
A review is given of recent Japanese research on the physiology and biochemistry of dormancy in the potato tuber. The influence of natural growth inhibiting and stimulating compounds on tuberization and sprouting is discussed. The ratio between these growth-regulating substances probably controls the shift in relative activity of different respiratory enzyme systems occurring on the termination of dormancy.
Zusammenfassung
Es wird berichtet über neue physiologische und biochemische, in Japan durchgeführte Untersuchungen in bezug auf die Keimruhe der Kartoffelknolle. Die Einflüsse, welche natürlich vorkommende wachstumshemmende und-fördernde Stoffe auf die Knollenbildung und die Keimung ausüben, werden behandelt. Das Verhältnis zwischen diesen Wachstumsregulatoren beeinflusst die Veränderungen der relativen Aktivität der verschiedenen Atmungsenzymsysteme die bei der Beendung der Keimruhe auftreten.
Résumé
L'auteur nous renseigne sur les recherches physiologiques et biochimiques sur la dormance de la pomme de terre récemment effectuées au Japon. Il traite l'influence des substances naturelles inhibitrices ou stimulatrices de croissance sur la formation des tubercules et la germination. La proportion de substances de ces deux groupes influence la modification des rapports d'activités des systèmes respiratoires à la fin de la dormance.
