Z Qili, Q Zhixiang
Guangxi Zhiwu, 1994•europepmc.orgThe somatic chromosome numbers in root-tip cells of Hippeastrum rutilum (Ker) Herb. are
found to 2n= 33. The karyotype formular is 2n= 3x= 33= 12m+ 9sm+ 12st. The length ratio of
chromosomesw is 2.07. Therefore, the karyotype belongs to “3B” of Stebinskaryotype
symmetry. The index of karytotype asymmetry (As. K%) is 72.59.
