Studies of the karyotype and sexual mechanism of propagation in Allium neapolitanum Cyr.

In this paper one population of A. neapolitanum from Makarska (Croatia) was investigated karyologically by a conventional staining method. To better understand the process of sexual reproduction in this polyploid species we analyzed chromosome pairing and meiotic irregularities in the prophase of meiosis in pollen mother cells. Data on pollen fertility, pollen mitosis and percentage of seed germination were presented. Estimation of sexual reproduction efficiency and its significance for karyotype evolution were discussed.
