Molecular characterization of the wild relatives of safflower (Carthamus tinctorius L.) in Turkey as revealed by ISSRs

In the present study, we used 39 plant samples representing six Carthamus taxa collected from different regions of Turkey: 11 of C. dentatus, 5 of C. glaucus, 18 of C. lanatus, 3 of C. persicus, 1 of C. tenuis subsp. tenuis and 1 of C. tenuis subsp. gracillimus. On these samples, we screened nine ISSR markers for polymorphic products. We generated 151 polymorphic bands. In a dendrogram based on these ISSR bands, the first branch was C. tenuis subsp. gracillimus, then C. persicus formed the second group. The rest of the taxa were grouped in two clusters: the first included C. lanatus, C. tenuis subsp. tenuis and C. glaucus, and the second included C. dentatus. Within the first cluster, C. tenuis subsp. tenuis and C. glaucus grouped together and then united to C. lanatus. Representatives of the same taxa consistently clustered together. Also within species, the groupings were generally concordant with their geographical distributions.

Pollen morphology of Carthamus L. species in Anatolian flora.

In flora of Turkey, there are six species of Carthamus L: Carthamus dentatus (Forssk.) Vahl., C. glaucus M. Bieb. subsp. glaucus, C. lanatus L., C. tenuis (Boiss. & Blanche) Bornm., C. persicus Desf. ex Willd. and C. tinctorius L. Within these species, C. tinctorius L. is an alien species for the Turkish flora. The pollen grains belonging to six taxa collected from different locations of Anatolia and examined both under light microscope (LM) and under scanning electron microscope (SEM). As a result of these examinations and measurements, pollen grains of taxa are radially symmetrical, isopolar, oblate-spheroid, spheroid, tricolporate rarely tetracolporate, echinate. There are high similarities among taxa but some differences are recorded in size and spin length. According to cluster analyses of Carthamus species’ pollens, C. glaucus and C. tenuis have the most similar pollens. C. dentatus grouped with these two. C. persicus placed as the closest relative of C. tinctorius in the dendrogram.

Crambe (Crambe hispanica subsp. abyssinica) Genotiplerinin Bazı Bitkisel Özelliklerinin Belirlenmesi

Bu calisma; Crambe genotiplerinin bazi bitkisel ozelliklerin belirlemesi amaciyla Ankara kosullarinda Tarla Bitkileri Merkez Arastirma Enstitusu Mudurlugu’nun Arastirma ve Uygulama tarlasinda 2013 yilinda yurutulmustur. Bu calismada materyal olarak ABD Ulusal Gen Bankasi’ndan temin edilen 82 adet Crambe ( Crambe hispanica subsp. abyssinica ) genotipinden elde edilen veriler kullanilmistir. Crambe bitkisinde, rozette kalma gun sayisi, bin tohum agirligi (g), bitki basina tohum verimi (g/bitki), tohumda yag orani (%) ve sabit yag asitleri bilesimi (%) belirlenmistir. Arastirma sonuclarina gore sapa kalkma gun sayisi 41 gun, bin dane agirligi 6,6g, bitki basina tohum verimi 2,3 g/bitki, tohumda yag orani %13,4, erusik asit orani %54, oleik asit orani %14,35, linoleik asit orani %9,41 ve linolenik asit orani %7,59 olarak belirlenmistir.
