Abstract

In the previous paper of 1979, the author reported that cyclamen could be vegetatively propagated by means of notching on the cut surface after the upper part of the planted tuber was scooped. In the present paper, the suitable site of tuber scooping and size of tuber notching for the vegetative propagation are examined. And the initial points of the adventitious buds developed on the scooping surface of the tuber and its margin, and of the adventitious bud occurring on the epidermis of the tuber are further observed from an anatomical viewpoint. The results are as follows: 1. The site of scooping and the size of notching. It seems to be suitable for this propagation that the tuber was scooped at one third of the upper part and the cut surface notched into one centimeter squares. 2. The point of initiation of adventitious bud primordia. In the case of adventitious buds growing from the scooping surface, the original body of the bud occurred in the vascular cut end and its periphery. On the other hand, in the case of adventitious buds growing from the margin of the scooping surface, the original body occurred in the meristematic layer, where old periderm and new wound-periderm joined together. And moreover, in the case of adventitious buds growing from the epidermis, the leaf primordia of the bud originated from the neighborhood of the cork cambium in the periderm.
