Germination percentage of rice seeds during accelerated aging treatment. For the accelerated aging treatment, the seeds were kept soaking in distilled water at 4°C for 90 days. The seeds were sampled and tested at 10 day intervals. Germination tests were carried out with 4 replicates of 100 seeds at 25°C for 14 days. *Different small letters in a same date (for vertical comparison) indicate significant difference of means at α = 0.05 by t-test. **Different capital letters in a same variety (for horizontal comparison) indicate significant difference of means at α = 0.05 by Duncan’s Multiple Range Test.
