Abstract:In order to research the influnce of provenances of Cunninghamia lanceolata on koryotype, seeds are collected from 20 different provenances, they are kept on the damp filters under the condition of 25℃ for germinating till their roots grow to 0.5cm in length. After being treated with 0.02M 8-hydxoxy quinoline for 4 hrs, they should be taken the slide preparation.Every chromosome complement consists of 22 chromosomes, and 1 or 2 B-chromosomes have been found among 5 provenances. The karyotype is one that has the nature of polymorphism which is characterized by its satellite shape and location and its heterozygous nature relevant to the shape and the location mentioned above. The satellites can be classigied into big-satellite, smallsatellite, compplex-satellite, linesatellite and T-satellite. The satellites usually settle down in a certain pair of chromosomes, they change their locations from one pair to another among the 1st to 5th pair as well. More often than not, the satellites are located on the short arms of the chromosomes, but a few of them have also been observed on the long arms of the chromosomes at times.Through miltivariate analysis, it is verified that the karyotype from Dechang provenances in Sichuan province is more individually geographical and ecological type than that of those which are from any other provenances. Gene drifting of that isn‘t obvious. Though the type is widely distributed among 19 provenances, its type are the same. It isn‘t influnce for latitude and longitude on variety, of satellite.
