Tokyo Kokei Standard Callus and adventitious roots

Copyright 1998-2022 Yoshiaki Yoneda

When sections of a stem or a hypocotyl of Ipomoea nil were cultured on an agar nutrient basic medium including plant hormones, a callus occurred and an adventitious root occurred easily. Root-like structures were produced from the bottom of the callus shown in the Figure. However, differentiation of adventitious buds was not found.
