东北地区小麦族11种植物的核型报道

In this paper the karyotypes of eleven species of Triticeae from Northeast China are reported. The karyotype formulae are as follows: Agropyron cristatum, 2n=4x=28=20m+8sm; Elytrigia repens, 2n=6x=42=34m(2SAT) + 8sm; Hordeum brevisubulatum, 2n = 4x = 28 = 20m + 8sm( 4SAT ); Roegneria nakaii, 2n = 4x = 28 = 20m + 8sm( 4SAT ); R. turczaninovii var. macrathera, 2n = 4x = 28 = 20m(2SAT ) + 8sm(2SAT ); Elymus sibiricus, 2n = 4x = 28 = 20m + 8sm ( 4SAT); E. dahuricus, 2n=6x=42=32m+10sm( 6SAT); E. excelsus, 2n=6x=42=32m+10sm( 6SAT); Leymus chinensis, 2n=4x=28=20m(4SAT) + 8sm; Roegneria ciliaris, 2n = 4x = 28 = 22m( 2SAT ) + 6sm( 2SAT ); R. kamoji, 2n= 6x = 42= 30m+ 12sm(4SAT). The karyotypes of the first five species are re-ported for the first time.
