    Pollen grain size of some species of Galium section Platygalium (Rubiaceae) have been studied in diploids (2 n = 2Γ— = 22, in G. boreale, G. valantioides, G. broterianum ), tetraploids (2 n = 4Γ— = 44, in G. boreale ), hexaploids (2n = 6Γ— = 66, in G. boreale ) and in dodecaploid (2n = 12Γ— = 132, in G. rubioides ), and many other species and specimens related to section Platygalium. Pollen grain size, for G. boreale diploide (P = 16.68 ΞΌm, E=15.76 ΞΌm), G. valantioides (P = 15.82 ΞΌm, E = 14.69 ΞΌm), G. broterianum (P = 15.94 ΞΌm, E = 14.97 ΞΌm); for G. boreale tetraploids (P = 17.15 ΞΌm, E = 17.21 ΞΌm); for G. boreale hexaploids (P = 18.83 ΞΌm, E = 18.80 ΞΌm) and (P = 20.87 ΞΌm, E = 21.63 ΞΌm) G. rubioides dodecaploid, was positively correlated with ploidy level. The results verify the expected correlation between mean pollen diameters and ploidy levels, and demonstrate that apparent di-, tetra-, hexa- octa-, deca-, dodeca- and possibly higher polyploidy occur among the species of sect. platygalium. Palynomorphological data revealed that in sect. Platygalium, pollen size can be directly associated with chromosome number and can also be used as an additional tool to establish evolutionary trends and taxonomic relationship among species.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ приводятся Π΄Π°Π½Π½Ρ‹Π΅ ΠΈΠ·ΠΌΠ΅Ρ€Π΅Π½ΠΈΠΉ ΠΏΡ‹Π»ΡŒΡ†Π΅Π²Ρ‹Ρ… Π·Π΅Ρ€Π΅Π½ Π²ΠΈΠ΄ΠΎΠ² Galium sect.
