study on chormosomes,of 8 Species of Calyeathaeeae。

Abstract: Detailed karyotype studies had been carried out for eight species from calyeanthaceae using the stem and root tips.The results showed that the basic number for all species was n=11.The absolute chromosome length ranged from7.02to~322m.The karyotype formulas were found:2n=22=22m for Calgcanthus floridus,2n=22=20m(2sat)+2sm for Chimonanthus campanulatus and2n=22=20m+2sm for C.occfdentalis,C.chfnensfs,Ch.praecox,Ch.nitens, Ch.grammatus and Ch.salicifolfus.A comparison of karyotypie symmetry among species indicates that genus Calycanthus is more Primitive than Chimonanthus in phylogeny,and C.floridus and Ch.salfcilolius are the most primitive species within their genus.
