In vivo callus formation on the surface of tubers of Manchu tubergourd (Thladiantha dubia, Cucurbitaceae)

Abstract

For the first time, shingles of callus-like structures were found in Thladiantha dubia. Of these formations, shoots and roots are intensively regenerated in vivo. Such a mechanism underlies the active vegetative propagation and wide distribution of this invasive species.
