On the classification criteria of tree seed level, the statistical method used in the study of classification of Robinia pseudoacacia (referred to as acacia locust) has been included in the national standard of tree seed level, which strictly controls the quality of seeds, Price, reasonable use of species is very necessary. According to mathematical statistics principles and methods for grading this approach is an improvement, the issue is proposed forest seed classification criteria for the selection of indicators and the rationality of the comprehensive index is worth further discussion. The main indicators to assess the quality of seeds are clarity, germination rate, life
