Effect of common bean (Phaseolus vulgaris L.) seed viability on drying dynamics

‘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.
