The values represent the averages (±SE) of four independent replicates followed by different letters within columns are significantly different at P ≤ 0.05, according to Duncan’s Multiple Range test. The data in parentheses indicate percent decrease in germination and mean germination time of wheat genotypes in comparison to their control values.
