Karyological Study of Four Species of Wheat Grass (Agropyron sp.)

A. Asghari, Y. Agayev and S.A.A. Fathi

Abstract:
Abstract: Karyological study of four Agropyron species (A. desertorum, A. cristatum, A. pectinoforum and A. imbricatum) showed that these species were tetraploid (2n = 4x = 28) with the base number, x = 7. In the studied cells of A. desertrum, 28 chromosomes with 1 B chromosome and satellite on chromosomes 2 and 4 were exist. The number of chromosomes in studied cells of A. cristatum ranged between 28 and 31 without B chromosome and with satellite on chromosome 3 and 5. In the cells of A. imbricatum that studied, 28 to 33 chromosomes with 1 to 3 B chromosomes and satellite on chromosome 7 were exist. The number of chromosomes in studied cells of A. pectinoforum ranged between 28 and 29 and 1 B chromosome and satellite on chromosome 3 were exist. Finally in the studded cells of four species 28-33 chromosomes were exist (the various forms of aneuploid cells). One to three B chromosomes and chromosomes with satellites also observed in these species.
