Abstract To explore the physical and chemical properties and their effects on seed germination of hot pepper（Capsicum annuum L.）seed coating agent（XFY-2），the pH value，viscosity，forming-film property，forming-film time，coating uniformity rate and coating off rate of seed-coating agent were tested．The 2 hot pepper seeds were coated with XFY-2 and indoor germination experiments were carried．Meanwhile its effects were compared with those of an imported seed-coating agent（SLS）．The results showed that the pH value of XFY-2 was 4.55，the viscosity was 23.0 mPa?s-1，forming-film property was good，forming-film time was 5.5 min，coating uniformity rate was 97.5%，coating off rate was less than 5%．The result of germination experiment indicated that the physical and chemical properties of this seed-coating agent were good．It could not only promote seed germination，enhance adult seedling rate，but also effectively improve seedling germination and development．The general effects of this hot pepper seed-coating agent were better than those of the imported agent SLS．
