Abstract:
The karyotypes of Eremurus in Xinjiang were studied.Their karyotype formulas are as follows:
E.altaicus(Pall.) Stev.2
n=2
x=14=4m+8sm+2st;
E.anisopterus(Kar.et Kir)Regel 2
n=4
x=28=4m+4sm+20st;
E.inderiensis(M.Bieb)Regel 2
n=2
x=14=10sm+4st.Our study has shown that
E.anisopterus,a species occurring in the southern margin of the Gurbantunggut Desert,was a tetraploid with 2
n=4
x=28,a new chromosome count for this species which had been previously reported as a diploid with 2
n=2
x=14.The karyotype evolution of
Eremurus in Xinjiang is discussed.
