Öğe Capparis L. (Kebere) cinsinin GAP (Güneydoğu Anadolu Projesi) bölgesindeki işlenmesi, ihracatı ve son populasyon durumu(2004) Akan, Hasan; Aslan, Mustafa; Eker, İsmailCapparis ovata Desf. var. palaestina Zoh. (kebere) ve Capparis spinosa L. var. spinosa bitkileri GAP (Güneydoğu Anadolu Projesi) bölgesinde doğal yayılış gösteren ve ihracatı yapılan önemli bitkilerdendir. Bu çalışmada, kebere bitkisinin kimler tarafından toplandığı, toplanma biçimi ve ülkemizdeki ihracat miktarlarının ortaya çıkarılması amaçlanmıştır. Bu çalışma ile bitkinin doğadaki son populasyon durumu tespit edilmiş ve çözüm önerileri getirilmiştir. Bu araştırma, 2003- 2004 yılları arasında bitkinin en yoğun toplandığı GAP bölgesi sınırları içerisinde yapılmış ve bu işle uğraşan kişiler, fabrikalar ve firmalar arasında aracılık yapan birçok kişi ve kuruluşlarla görüşülerek veriler ortaya konmuştur. Çalışmalar sonucunda, başta ABD olmak üzere, İspanya ve diğer Avrupa ülkeleri, Ortadoğu ve Uzakdoğu ülkelerine yıllık ortalama 3.000 ton işlenmemiş ve 3.500 ton işlenmiş kebere bitkisinin çiçek tomurcukları ve meyvelerinin ihraç edildiği tespit edilmiştir. Bu çalışmada bitkinin arazide nasıl toplandığı, fabrikada nasıl işlendiği ve tomurcuk ile meyvelerinin paketlenme basamakları da fotoğraflarla verilmiştir.Öğe Check-list of the genus Colchicum in the Flora of Turkey(2005) Akan, Hasan; Eker, İsmailA check-list of the genus Colchicum L. in the Flora Turkey is presented, with 36 taxa. A list of taxonomical changes that have occurred since the publication of the Flora of Turkey suppl. 11 is given. Twenty-seven of them are autumn-flowering species (28 taxa), whereas 8 of them are early-spring species. Thirty-five species (36 taxa) are presented, of which 15 are endemic to Turkey.Öğe The flora of Kaşmer Da?i (Şanliurfa, Turkey)(2005) Akan, Hasan; Kaya, Ömer Faruk; Eker, Ismail; Cevheri, CenapThis research was carried out from 2001 to 2004 in order to determine the flora of Kaşmer Da?i. The research area is situated in Şanliurfa province and within C7 of the grid system. In the area, 262 taxa belonging to 47 families, and 156 genera were determined.

In all, 789 plant specimens that consisted of 104 taxa belonging to 13 families and 30 genera were gathered from the investigation area. Of all the collected specimens, 19 taxa were new records for C6, C7, and C8, and 11 taxa were endemic to Turkey. Scilla mesopotamica Speta, which was first collected from Şanliurfa-Halfeti in 1888 by Sintenis and was considered a missing species, was rediscovered after 116 years during this study. Colchicum crocifolium Boiss. was also determined as a new record for Turkey. According to floristic regions, Irano-Turanian elements ranked first among the specimens, accounting for 47.12%, followed by Mediterranean elements (25.00%) and Euro-Siberian elements (0.96%). Some of the identified species (26.92%) were widespread and of unknown phytogeographic origin. In addition, 86.54% of the collected taxa were determined to be monocotyledons and the remaining (13.46%) were dicotyledons. The families with the most taxa in the research area were Liliaceae (59) and Iridaceae (14). Concerning the number of species, the major genera in this region were as follows: Allium L. (17), Ornithogalum L. (10), Gagea Salisb. (9), Bellevalia Lapeyr. (6), and Iris L. (6). Moreover, of all collected taxa, 57.69% were bulbous, 21.15% were tuberous, 17.31% were cormous, and 3.85% were rhizomous. Concerning flowering time, 93.27% of the taxa bloomed in early-spring and spring, while 6.73% bloomed in autumn. © TÜBİTAK.Öğe The geophytic flora of Şanlıurfa province, Turkey(2008) Eker, İsmail; Koyuncu, Mehmet; Akan, HasanThis study was carried out between 2001 and 2004 to determine the geophytic flora of Şanlıurfa, located within C6, C7, and C8 of the grid system in Turkey.

Chromosome lengths were determined between 1.29-1.74 mu m in Trigonella astroiles Fischer & C.Meyer, 1.06-1.44 mu m in Trigonella fischeriana Ser., 1.67-2.59 mu m in Trigonella velutina Boiss., 0.98-1.49 mu m in Trigonella cretica (L.) Boiss., 1.1.6-1.81 pm in Trigonella coerulescens (M.Bieb.) Hal., 0.99-1.72 mu m in Trigonella procumbens (Bess.) Rchb., respectively. All species are diploid with 2n=14,16 and 18 chromosomes and the karyotypes of all species consist of metacentric chromosome pairs. Trigonella velutina has only satellites on the long arms of chromosome 2 and 6. The karyotype analysis of these species was first time Counted in Turkey.Öğe Last two hundred individuals: Rediscovery of scilla mesopotamia speta (Hyacinthaceae), a threatened endemic species in Turkey(Polish Botanical Society, 2010) Eker, İsmail; Akan, HasanIn this paper, the rediscovery of endemic and long missing species, Scilla mesopotamica Speta which had been only known from the type gathering, is given. The species has not been collected again after Sintenis in 1888, whose specimens served Speta for description of the new taxon. In 2004, the authors found it in a steppic rocky area, near Halfeti in Şanliurfa province, South East Anatolia, Turkey. After analyzing Sintenis' original collection notes, they concluded that this area is identical with the type locality. 5. mesopotamica has an extremely limited distribution and is represented by less than 200 specimens in the single known population that covers less than 50 m2. Taxonomy of the species, detailed description with illustrations, geographical distribution, habitat, ecology and status of IUCN extinction risk and some comments on conservation of the plant are also presented.Öğe Last two hundred individuals: rediscovery of Scilla mesopotamica Speta [Hyacinthaceae], a threatened endemic species in Turkey(Polskie Towarzystwo Botaniczne, 2010) Eker, İsmail; Akan, HasanIn this paper, the rediscovery of endemic and long missing species, Scilla mesopotamica Speta which had been only known from the type gathering, is given.

Dewar) bowles (Iridaceae) in Turkey(Pakistan Botanical Soc, 2007) Akan, Hasan; Eker, Ismail; Satil, FatihIn this investigation, some morphological and anatomical characteristics of Crocus leichtlinii (D.Delwar) Bowles, an endemic species which has flowering time in early spring, were observed. The specimen was collected from Sanliurfa, South East Anatolia, within C7 of the grid system; its habitat and population status was also determined. Morphological features of species such as leaf, bracteol, flower, and fruit have been described in detail. The determination of the anatomical characteristics present the first data available in the literature. In anatomical studies, transverse sections of leaf and root have been examined and supported by illustration. Anatomical characters of species were observed to have been similar to usual features of Iridaceae anatomy.Öğe The morphological and anatomical properties of endemic Crocus leichtlinii (D.
