A karyological study on taxa of Coronopus DC section of Plantago L. genus (Plantaginaceae) in Turkey

Abstract

In this study the chromosome number and morphology of five taxa of the Coronopus D.C. section - Plantago coronopus subsp. coronopus L., P. coronopus subsp. commutata (GUSS.) PLGER, P. crassifolia FORSSKAL, P. maritima L., and P. holosteum SCOP. (Plantaginaceae) - in Turkey were investigated using karyological techniques. The seeds of taxa were collected from natural habitats. The chromosome numbers are determined for four taxa (P. coronopus subsp. coronopus, P. coronopus subsp. commutata, P. crassifolia and P. maritima) as 2n = 4x =20 and one taxon (P. holosteum) as 2n = 2x = 12. The chromosome numbers and karyotype analysis of the species are reported for the first time for Turkey.
