Breeding systems and cytology in Greek populations of five Limonium species (Plumbaginaceae).

摘要

Information is provided about the reproductive mechanisms and the chromosome numbers of Limonium palmare, L. roridum, L. graecum, L. virgatum and L. narbonense, notes on their taxonomy are given and the correlation between their breeding systems and cytology is discussed. L. palmare and L. roridum are facultatively apomictic with 2n=4x=34 and 2n=5x=43, respectively. L. graecum is apomictic and its chromosome number of 2n=6x=52 is reported for the first time, L. virgatum is also apomictic with 2n=3x=27 and L. narbonense is sexual with 2n=6x=54 and 2n=8x=72. The latter number is a new record and the highest number reported so far for the genus Limonium..
