    tion of tuber formation is based upon the review of Vreug-denhil and Struik (1989). Four developmental steps are ne-cessary for tuber formation in potato plants: (1) stolon in-duction and initiation from axillary buds, (2) stolon growth and branching, (3) cessation of longitudinal growth of the stolon, (4) tuber induction and initiation. Tubers of potato (Solanum tuberosum L.) plants serve as organs for vegetative propagation and stock of matter and energy for the next generation.
