Cariologia i distribució del gènere Bromus L. (Sec. Pnigma Dumort. i Sec. Ceratochloa (Beauv.) Griseb.) a Catalunya
The karyotypes of the four perennial species of Bromus found in Catalonia have been elaborated. The chromosome formula and asymmetry index are calculated following Stebbins (1971) and Romero-Zarco (1986). The chromosome numbers of B. willdenowii Kunth. (2n = 42, n = 21 and 2n = 28), B. erectus Huds....

| Sumario: | The karyotypes of the four perennial species of Bromus found in Catalonia have been elaborated. The chromosome formula and asymmetry index are calculated following Stebbins (1971) and Romero-Zarco (1986). The chromosome numbers of B. willdenowii Kunth. (2n = 42, n = 21 and 2n = 28), B. erectus Huds. (2n = 42, n = 21 and 2n = 56), and B. inermis Leyss. (2n = 42), are confimed. We include the chromosome number 2n = 56 for B. ramosus Huds., stablished for the first time. The distribution in Catalonia of the taxa is studied. |
