متن کاملChromosome Numbers for Some Erodium L'Hér (Geraniaceae) Species of Iran
Erodium (Geranaiceae) species are distributed in different habitats of Iran. Some species are of medicinal importance while some are well known weeds. There are no chromosome counts for Erdoium species of Iran. Chromosome numbers are given for six taxa of Erodium (Geraniaceae) from Iran: E. cicutarium (2n=36), E. ciconium(2n=18), E. malacoides (2n=20), E. moschatum (2n=20), E. neuradifolium (2n...

متن کاملChromosome-Numbers in Bromeliaceae
Eighty-three chromosome counts are reported for 72 taxa of the Bromeliaceae. Fifty-eight of these counts are the first known chromosome number reports for their respective taxa. A model of chromosomal evolution in the Bromeliaceae (n = 25) is presented. The model is parsimonious and consistent with existing data on meiotic chromosome numbers within the family and in the closely related Vellozia...
متن کاملChromosome Numbers and Karyotypes of Four Species Rubus L. from North of Iran
Karyotype study was performed across 7 populations of 4 Rubus species growing in Iran. The results showed that the chromosome numbers of R. sanctus (2n=2x=14) diploid, R. caesius, and R. discolor were (2n=4x=28) tetraploids, R. persicus (2n=8x=56) octoploid. The chromosome numbers of R. discolor, and R. persicus were reported here for the first time. Karyotypic formula also varied between the s...
