In order to contribute to the knowledge of the taxonomic relationships between some species of the Quercus genus, the karyomorphology of 4 species (Quercus ilex L., Q, suber L., Q. robur L, and Q. pubescens WILLD.) was carried out. The somatic chromosome number 2n=24 was found in all taxa examined. An evident differentiation in karyotype structure of Q. ilex compared to other previous studied species has been found. Quercus suber, Q. robur and Q. pubescens possess moderately asymmetrical karyotypes. Q. suber differs from other species of the subgenus Cerris on the basis of karyological data showing similarities with Q, robur and Q. pubescens.

Abstract
In order to contribute to the knowledge of the taxonomic relationships between some species of the Quercus genus, the karyomorphology of 4 species (Quercus ilex L., Q, suber L., Q. robur L, and Q. pubescens WILLD.) was carried out. The somatic chromosome number 2n=24 was found in all taxa examined. An evident differentiation in karyotype structure of Q. ilex compared to other previous studied species has been found. Quercus suber, Q. robur and Q. pubescens possess moderately asymmetrical karyotypes. Q. suber differs from other species of the subgenus Cerris on the basis of karyological data showing similarities with Q, robur and Q. pubescens.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
