Study on the Germination of Paulownia Tomentosa Seeds in Different Provenances and Its Cluster

This paper dealt with the studying the germination percentage. germination potential and analyzing thegermination of the seeds wtith different treatments by systematic statistics method Seeds were collected from 14 prove-nances in September 1994. The results indicated that the germination percentage and germinalion potential of the seeds invarious provenances were different. Both indexes in Nanchang area was much lower than those in the rest provcnances.The germination percentage and germination potenlial of the seeds in different provenance deelined after the seeds weretreated with aging for one year. The light treatment might promotes the germination percentage more effectively than thegermination potential. In addition. fuzzy cluster may refleet the relationship among germination in different protenances.
