Germination is typically small in December,
but mostly in January and February, respectively. Maximum germination is
observed during the spring and summer seasons. This phenomenon is not due to
dormancy or secondary dormancy since germinability has a similar curve every
year during long-term seed storage, only the number of germinative seeds
decreases stepwise every year at each storage month. Each species or crop
variety has a standard germination course throughout the year. There are also
species (crops) that have an almost constant germination process throughout the
year, i.e. without variation during the year, although there are a minority of
genotypes, but rather exceptions. From the theoretical practical point of view,
there is a probability (but not a certainty!) that genotypes should be tested
at the beginning or end of the year in case of seed germination. This
phenomenon has a negative effect on seed certification by companies growing
seeds for cultivation practise in some plants, with great variability of
germinability during the year.
