| Résumé : |
"Analysis of populations of Centaurium erythraea Rafn subsp. erythraea and C. Iittorale (D. Turner) Gilmour subsp. Iittorale has shown that both show a wide range of morphological variation. Much of this variation is retained in cultivation and five varieties are recognized of subsp. erythraea and four of subsp. Iittorale. Despite this variation the two subspecies are quite distinct. Analysis of mixed populations of the two species from the coasts of Anglesey and Lancashire has shown tbat some plants are, to varying degrees, intermediate and probably of hybrid origin. In the majority of populations from the Lancashire coast, backcrossing to C. [ittorale appears to have taken place, although two suggest backcrossing to C. erythraea. This is in contrast to the situation in the population from Anglesey in which only F.-like hybrids were present. Analysis of two populations from northern Germany show all plants to be intermediate and F.-like." (source : auteur) |
