Comparative anatomical study on eight Scilla taxa (S. bifolia, S. melaina, S. siberica subsp. armena , S. leepii, S. ingridae, S. mesopotamica, S. autumnalis and S. cilicica) growing in Turkey was made using light microscopy techniques. Leaf and scape anatomical properties of the taxa were compared and relationships among taxa were determined. In anatomical studies, paraffin method was used. The cross-sections of the scape, leaves and surface-sections the leaves of these taxa were taken and photographed. Length and width measurements of stomata in the upper and lower surfaces of leaves were made and the mean and standard devition values of stomata were calculated. Raphida crystals were found in the mesophyll of all taxa. On both surfaces of leaves, anomocytic type stomata were observed. The different and similar anatomical characters in the leaf and scape were determined and the taxa were classified into three groups; such as (1) S. ingridae, S. mesopotamica, S. melaina, and S. leepii are independent species with close relationships; (2) S. bifolia, S. siberica subsp. armena and S.cilicica are very close taxa; (3) S. autumnalis is different from other investigated taxa. Also, these taxa can be distinguished as mesophyll type; isolateral (S. bifolia, S. cilicica and S. siberica subsp. armena) and unifacial (S. melaina, S.leepii, S. ingridae, S. mesopotamica and S. autumnalis). According to our data, S. bifolia was considered as a complex species of Scilla genus in Turkey.

“…S. autumnalis has widespread distribution in Turkey, Mediterranean, South-Western England, Portugal, Libya and North Africa. Vaughan et al (1997) reported it as complex or cryptic species. However, it was critically endangered in some countries (specially, Romania) and was taken into protection in Romania (Banciu et al, 2010).…”

Ecological properties of some Scilla L. taxa [S. bifolia L., S. melaina Speta, S. siberica Haw. subsp. armena (Grossh.) Mordak, S.leepii Speta, S. ingridae Speta, S. mesopotamica Speta, S. autumnalis L., S. monanthos C. Koch., S. rosenii C. Koch.and S. cilicica Siehe] were compared and relationships among taxa were determined. S.leepii and S. mesopotamica are endemic to Turkey. Because of various reasons, S. melaina, S. leepii, S. ingridae, S. mesopotamica, S. monanthos, S. siberica subsp. armena, S. rosenii and S. cilicica have limited distribution in Turkey. The investigated taxa have fragrant flowers, so are used as ornamental plant in gardens, parks and balconies in Turkey. Soil samples of the taxa were taken in flowering periods and physical and chemical properties (texture class, % of total salinity, pH, % of CaCO3, % of organic matter, % of total N, P, K, Ca, Mg, Mn, Cu, Fe and Zn (in mg/kg) were determined. According to the similarities and differences in ecological characteristics, the taxa were divided into four groups. 1 st group: S. melaina, S. leepii, S. ingridae and S. mesopotamica; 2 nd group: S. siberica subsp. armena and S. cilicica; 3 rd group: S. bifolia and S. autumnalis; 4 th group: S. rosenii and S. monanthos. From the data, it has been found that organic matter, N, P, K, Ca, Fe and Zn values are more effective than the other soil factors in the distributions of the investigated taxa.

Cytotypes B , endemic to Libya, underwent independent reductions of base chromosome numbers to x = 6 and x = 5, respectively, as well as increases of genome sizes (1C of 6.27 pg and 4.68 pg, respectively) [Jang et al, 2013].…”

Polyploidy and hybridization play an important role in plant diversification and speciation. The application of genomic in situ hybridization (GISH) allows the identification of parental genomes in hybrids, thus elucidating their origins and allowing for analysis of their genomic evolution. The performance of GISH depends on the similarity of the parental genomes and on the age of hybrids. Here, we present the formamide-free GISH (ff-GISH) protocol applied to diploid and polyploid hybrids of monocots (Prospero, Hyacinthaceae) and dicots (Melampodium, Asteraceae) differing in similarity of the parental genomes and in chromosome and genome sizes. The efficiency of the new protocol is compared to the standard GISH protocol. As a result, ff-GISH allowed efficient labeling and discrimination of the parental chromosome sets in diploid and allopolyploid hybrids in Prospero autumnale species complex. In contrast, the standard GISH protocol failed to differentiate the parental genomes due to high levels of similar repetitive DNA. Likewise, an unambiguous identification of parental genomes in allotetraploid Melampodium nayaritense (Asteraceae) was possible after ff-GISH, whereas the standard GISH hybridization performance was suboptimal. The modified method is simple and non-toxic and allows the discrimination of very similar parental genomes in hybrids. This method lends itself to modifications and improvements and can also be used for FISH.
