Effects of different treatments on seed germination of Fenyu strawberry
Effects of physical,chemical and biological enzymes treatments on germination of Fenyu strawberry were investigated.The results showed that soaking seeds with 98％concentrated sulfuric acid for 2 to 10 mi-nutes could significantly improve the germination ability of the seeds,compared with the purified water control(CK).Soaking seeds for 10 minutes had the best effect,which increased the germination energy of Fenyu No.1 and Fenyu No.2 by 8.26 and 23.36 times,and the germination rate by 19.5％and 14.2％,and de-creased the average germination time by 50.4％and 55.6％,respectively.However,acetic acid,sodium hy-droxide and hydrogen peroxide solution treatments significantly inhibited the seed germination,and the germi-nation energy of Fenyu No.1 and Fenyu No.2 was decreased by more than 45.5％,and the germination rate was decreased by more than 9.7％,compared with control.In addition,sandpaper polishing and concentrated sulfuric acid soaking had positive effect on the germination of stored seeds.The germination energy of Fenyu No.1 and Fenyu No.2 stored seeds polished by sandpaper was increased by 3.00 and 7.73 times,and the ger-mination rate was increased by 60.2％and 81.2％,compared with control.Compared with control,the germi-nation energy of stored seeds soaked in 98％concentrated sulfuric acid for 10 minutes was increased by 23.16 and 24.09 times,and the germination rate was increased by 72.9％and 122.6％,respectively.
