Journal of the Minnesota Academy of Science
The leaves of three cultivars of Cyclamen persicum were examined at several stages of development in order to determine the pattern of elongation in both the lamina and petiole. Although there is a considerable literature on lamina elongation, relatively little is known about the growth of the petiole. In the latter structure it is usually assumed that an intercalary meristem is involved. Elongation of the young leaf is initially due to activity distributed throughout the deve1opint organ. Maturation of the leaf progresses acropetally from the base of the petiole and basipetally from the tip of the lamina. As the leaf …
