* p ≤ 0.10, ** p ≤ 0.05, *** p ≤ 0.01 (Compared to positive control group. i.e. γ-radiation)
#p ≤ 0.10, ##p ≤ 0.05, ###p ≤ 0.01 (Compared to negative control group. i.e. sucrose control)
The percentages in parentheses indicates the decrease rates in the mutation frequency of test groups as compared to positive control group
