표 Materials of weedy rice. Weedy rice was classified according the collected area then 100 kinds of weedy rice were selected as materials. Number of weedy rice used in each province was determined by the registered rate in each province
표 Cultivation of weedy rice for testing of emergence characters using (A) low dormancy and (B) high dormancy weedy rice genetic resources. Low or high dormancy weedy rice was classified according to the germination rate of 80%. Seed was sowed at different soil depth conditions with three replications. Low dormancy weedy rice was cultivated at 15/5℃, 16/6℃, 17/7℃, 18/8℃, 19/9℃ with 13 hours light condition. High dormancy weedy rice was cultivated at natural condition from November in to 2015 to May in 2016

표 Emergence rate of low dormancy weedy rice according to brown rice color, (A) red and (B) white, under different temperature conditions at 30 days after sowing. Same letters are not significantly different at p < 0.5 (Duncan’s multiple test)
표 Relation of effective accumulated temperature (℃) with emergence rate (%) under different soil depth conditions in low dormancy weedy rice. Effective accumulated temperature was calculated by sum the mean temperature above 10℃
표 Emergence rates of high dormancy weedy rice under the natural condition. (A) Emergence rates (%) of weedy rice at middle of May and (B) increase of emergence rate (%) according to effective accumulated temperature under different soil depth conditions. Effective accumulated temperature was calculated by sum the mean temperature above 10℃. Same letters are not significantly different at p < 0.5 (Duncan’s multiple test)
표 Changes in relative emergence rate (%) according to effective accumulated temperature under different soil depth condition. The relative germination rate was calculated from the germination rate at that point, assuming that the final germination rate was 100%. The curves in the graph were fitted to a logistic equation as shown in Table 2. Horizon lines indicate the 80% and 90% of relative emergence rate
표 Emergence rate (%) under different soil depth conditions. (A) Emergence rate in 1 and 5 cm of soil depth according to effective accumulated temperature. (B) Difference of emergence rate (%) between 1 and 5 cm of soil depth conditions according to effective accumulated temperature.

The 0 cm of flooding depth was control treatment which treated enough water to seed germination. Flooding treatment was conducted for four weeks. Emergence rate was checked at three weeks after drained of water when emergence finished
표 Distribution ratio (%) of weedy rice germplasm by emergence rate under different soil and water depth. The 100 accessions of weedy rice germplasm were used as materials. Soil depth was treated as 1 and 5 cm and water depth was treated as 5 and 10 cm. Range of emergence rate was divided by 10 % in the range of 0 to 100 %

Emergence rate (A, B), dead seed rate (C, D) and germination rate under soil (E, F) were checked at 30 days after water draining. Effective accumulated temperature was calculated by cumulating the average temperature over 10 ℃ in each temperature condition
표 Emergence rate (%) according to different flooding periods under 5 cm of flooding depth (A) and 10 cm of flooding depth (B) condition. Seed of weedy rice germplasm were sowed under 5 cm of soil depth then treated different water depths, cultivated at different temperature conditions until emergence was finished
