Hormonal regulation of tuber formation in potato plants

Tuber formation is a complex process comprising several stages: stolon formation and growth, induction of tuberization, tuber initiation, and tuber growth. This review considers successive stages of tuber formation and their hormonal regulation. Special attention is paid to the effects on tuber formation of such phytohormones as gibberellins, cytokinins, jasmonic acid, and auxins. Physiological and some molecular-genetic aspects of their action on tuber photoperiodic induction and initiation are discussed.
