Abstract： On the basis of summarizing the seedling raising time， soil selection and treatment， seed treatment， sowing and post-germination management techniques， the seed stratification time and temperature were optimized. It was found that the best stratification environment is to put begonia seeds at 5 ℃ for 40 days， and the traditional method of stratification of 50 cents for 60 days was modified.

Keywords： begonia; stratification temperature; stratification time; germination rate; seedling rate
