The algorithm of the organogenesis cycle in the potato, in its basis, represents a software which defines the interrelationship at the time of onset as well as the duration of all phenophases, i.e. of all the processes of organ and tissue differentiation in the annual cycle of potato development. All the phenophases and processes of organ and tissue differentiation in the potato, from the time of emergence up to the tuber development (the differentiation of the tuber from the stolon), could be defined as algorithmic steps. In this way each new piece of information in the process of differentiation or any newly defined effect of a certain factor can be additionally included, as new steps or a complete algorithm, into the integral algorithm of the organogenesis cycle in the potato. The level of the estimation of this process is determined by the user's requirements.
