This study was conducted to investigate the impact of light conditions and wet cold treatments on the characteristics of seed germination patterns of several wild vegetables. The 1,000-grain weight of wild vegetables ranged from 0.08 to 14.5 g. The germination rate of 9 species grown under light conditions was relatively higher than that of those grown under dark conditions. The germination rate of 10 species subjected to seed prechilling (2°C for 50 days) was relatively higher than that of the control. The average number of days to germination for 12 species (Adenophora triphylla var. japonica (Regel.) Hara, Allium sacculiferum Maxim, Allium senescens L., Aruncus dioicus var. kamtschaticus (Maxim.) Hara, Aster scaber Thunb., Asyneuma japonicum (Miq.) Briq., Cirsium setidens (Dunn) Nakai, Crepidiastrum denticulatum (Houtt.) Pak & Kawano, Ligularia fischeri (Ledeb.) Turcz., Peucedanum japonicum Thunb., Platycodon grandiflorum (Jacq.) A.DC. and Synurus deltoides (Aiton) Nakai) subjected to seed prechilling was lower than that of the control. In particular, the value of ΔADG following wet cold treatment was the lowest at -9.5 days and was the lowest for Adenophora triphylla var. japonica at -8.2 days, Aruncus dioicus var. kamtschaticus at -7.9 days, Peucedanum japonicum at -7.9 days, Allium senescens at -7.0 days, Aster scaber at -6.2 days and Allium sacculiferum at -6.1 days. The germination coefficients (ΔCG value 9.5－21.6) of four species Ligularia fischeri, Cirsium setidens, Synurus deltoides and Adenophora triphylla var. japonica were considerably increased by the wet cold treatment. However, Allium microdictyon, Heracleum moellendorffii Hance and Aralia elata (Miq.) Seem. did not germinate in all treatments.
