Potato Germination

Solanum tuberosum L.

For potatoes, the concept of germination is associated with vegetative propagation by tubers and is expressed either as the ability of tubers to produce sprouts or as field emergence — the percentage of sprouted plants relative to the number of tubers planted.

In the reference 8 varieties crop Potato, where this is mentioned in the description.

The sprouting ability of tubers is evaluated by taking samples of the planting fraction, which are kept in the dark at a temperature of 15–20°C for 2–3 weeks. The primary criterion here is the proportion of tubers that have formed normal sprouts, which serves as an indicator of the potential of the planting material.

Field emergence of potatoes is defined as the ratio of the number of emerged sprouts to the number of tubers actually planted. This indicator depends not only on the quality of the seed material but also on soil conditions, aeration, agrotechnical practices, and the phytosanitary status, including disease incidence.

Different potato varieties possess varying abilities for sprout regeneration and germination stability. Low germination rates are often caused by improper storage conditions, exposure to soil toxins, frosts, or waterlogging, which negatively affects plant stand density.
