Four types seeds of Idesia polycarpa Maxim. from Lichuan city,including wild red fruit type,cultivated yellow fruit type,grafting red fruit type and cultivated red fruit type were selected and treated by different soaking treatment（tap water soaking,10.5 mmol/L KH2PO4 soaking,20% detergent soaking,10% soap soaking and 20% detergent solution soaking） to analyze the effects of different soaking time, soaking temperature and germination temperature on the seed germination of 4 types of yam. The results showed that soaking in 20% liquid detergent solution for 24 h with soaking temperature at 30 ℃ and accelerating germination temperature at 25 ℃,the seeds （wild red fruit type,cultivated yellow fruit type,grafting red fruit type and cultivated red fruit type） germination rate was 97.3%,95.1%,96.2%,and 97.3%,respectively,and the germination potentials were 68.1%,67.7%,65.8%,and 66.1%,respectively,which were significantly higher than other treatments,especially significantly higher than the tap water soaking treatment. 20% detergent soaking solution for 24 h,and seed soaking temperature 30 ℃,accelerating germination temperature 25 ℃,could effectively promote the seed germination. It is worthy of popularization and application in production practice.
