Germination percentage of seeds after a number of freezing treatments in weedy rice (PBR, WD-3) and cultivated rice (Hopum, Ilpum). The seeds were imbibed at 4°C for 24 hours and drained on paper towel. Next, they were frozen at −10°C for 24 hours, and then thawed at 4°C for 24 hours. This was one cycle of freezing treatment. After 1 to 3 cycles of treatment, germination was tested at 25°C for 14 days. . *Different letters on the bars in a treatment indicate significant difference of means at α = 0.01 by Duncan’s Multiple Range Test.
