Mediterranean plant karyological data – 33
For the first time, the chromosome number was determined for 5 species of the genus Pyrus L. (Rosaceae) from Armenia, viz. P. daralaghezii, P. hyrcana var. yeghegisi, P. medvedevii, P. oxiprion, P. takhtadzhianii, and the previous count of chromosome number for P. caucasica was confirmed. All the explored species have a diploid chromosome number 2n = 34 with the basic chromosome number x = 17.
