‘Tina’ and ‘Libra’ cultivar seeds of the common bean (Phaseolus vulgaris L.)
beginning germination capacity of 98%, were subjected to artificial ageing. In the
thermal chamber, they were twice treated for 72 hours at 45°C. After the treatment,
the seeds had lower viability. They germinated at 12% and 0% for ‘Libra’ and
‘Tina’ cultivars, respectively. The dynamics and rate of seed drying were measured
in samples with high and low viability. It was found that the seeds of both cultivars
with high viability, expressed by high germination capacity, dried at a slower rate
than ones with low viability. In the future, this method of estimating the drying rate
could probably be used to test seeds with different degrees of viability.
