During long-term storage of gene bank accessions, even under excellent conditions,
seed viability declines with period of storage, resulting in seed death. On the other
hand, regeneration of gene bank accessions should be done as rare as possible,
because, each time an accession is regenerated, there is a risk that the genetic
integrity of accession is compromised by genetic drift, selection, or gene flow.
Occasionally it happens that the sample's viability drops below the standard level,
when there is a risk that regeneration from such a sample disrupt the identity and
integrity of an originally collected sample. Different pre-sowing treatments are
often used to improve seed germination and early seedling growth in various crops.
The aim of this study was to evaluate the effect of three different seed priming
treatments on four maize gene bank accessions, stored for 5 and 30 years under
medium-term conditions (t=4-5°C; RH=45-50%). The standard seed germination
test on filt...er paper (BP, 20⇔30°C, ISTA Rules) and cold tests were performed.
The following parameters were observed: germination including germination
energy, seedlings fresh and dry weight, as well as seedlings length. Data analysis
showed that the treatments had a positive effect on the seedling’s fresh and dry
weight, but not on the seedling’s length. Also, seed priming treatments improved
germination dynamics.
