Özet
In this study, the possibility of controlling ageing processes in onion seed using prestorage treatments was investigated. Onion seeds cv. Texas Early Grano were treated with two different potassium salts (0.1M KNO3 and 0.1M KH2PO4) prior to storage. Both potassium treated seeds and untreated seeds (control) were stored at various combinations of seed moisture content (6%, 9% and 12%) and temperature (5 degreesC and 30 degreesC) for up to one year. Potassium treatment of seeds stored at 5 degreesC had no significant effect on germination. However, depending on the moisture content of seeds stored at 30 degreesC, treatments enhanced germination capacity by delaying the ageing rate of seeds. Besides improved germination capacity, potassium treatments prior to storage resulted in an increase in protein and sugar content and a decrease in amino acid leakage of seeds. This indicates that the effect of the treatments on the control of the ageing process is probably due to a delay of the deterioration in membrane integrity and protein degradation in onion seeds.
