Group I: tap water (control), Group II: 25 mg/L BBE, Group III: 50 mg/L BBE, Group IV: 20 μg/L penoxsulam, Group V: 20 μg/L penoxsulam + 25 mg/L BBE, Group VI: 20 μg/L penoxsulam + 50 mg/L BBE. Data are shown as mean ± standard deviation (SD). The averages shown with different letters in the same column are statistically significant (P < 0.05). SC: Sticky chromosome, FRG: Fragment, UDC: Unequal distribution of chromatin, B: Bridge, VC: vagrant chromosome CM: c-mitosis.
