Summary

While investigating the formation of adventitious sprouts from L1 tissue in potato as part of our work on potato mutation, we tested the ‘Jørgensen’ method.

This unpublished method of raising sprouts at the base of plantlets that have been severed from tubers was tried with our red-splashed, stable monectochimeric clones B165 and EM52.

The changes of tuber colour from fully-grown (adventitious?) sprouts allowed us to draw the following conclusions:

  1. 1.

    The new sprouts cannot be of epidermal origin, since no yellow-tubered progeny were obtained.

  2. 2.

    The many red-splashed tubers that were obtained must be of axillary origin, i.e. from axillary buds at the edges of the fracture.

  3. 3.

    The red tubers may be of adventitious origin, but uncovering via layer perforation is not excluded the more so as a regeneration time of three weeks is rather short for adventitious origin.
