Abstract:
With Peucedanum praeruptorum Dunn seed from Hubei Province as material,based on index of clarity,thousand-grain weight,seed moisture,seeds germination percentage,by using K clustering analysis method to establish the classification standard.The results showed that the seeds of Peucedanum praeruptorum Dunn in Hubei Province could be divided into three grades considering the rapid and effective,practicability,maneuverability which of each grade should reach the following requirements for the first grade seeds germination percentage≥60%,thousand-grain weight ≥2.0 g,purity ≥90%,seed moisture ≤10%;for the second grade seeds germination percentage 60%-50%,thousand-grain weight 2.0-1.8 g,purity 90%-85%,seed moisture≤11%;for the third grade seeds was unqualified seed which was short of the seed of the secondary.
