Phalolepıs Cass. DC. Seksiyonuna Ait Endemik Centaurea L. Türlerinin Tohum Çimlenmesi Üzerine Işık Etkisi
Öz
Dünya’da 600 Centaurea L. türü yayılış gösterirken, Avrupa’da 221 tür bulunmaktadır. Türkiye’de Astragalus L. ve Verbascum L. cinslerinden sonra Centaurea en çok türe sahip üçüncü cinstir. Endemizm oranı yüksektir yaklaşık%63 . Bu çalışmada Centaurea L. cinsi Phalolepis Cass. DC.seksiyonuna ait 8 endemik türün tohum çimlenmesi üzerine ışık etkisi araştırılmıştır. C. cadmea Boiss., C. aphrodisea Boiss., C. amaena Boiss. & Bal., C. lycia Boiss., C. luschaniana Heimerl, C. wagenitzii Hub.-Mor., C. tossiensis Freyn & Sint., C. hieropolitana Boiss. . Işık etkisi üç farklı fotoperiyotta 16 s aydınlık: 8 s karanlık, 16 s karanlık: 8 s aydınlık, 24 s karanlık ve 25 o C sıcaklıkta belirlenmiştir. Her deney serisinde 100 olgun tohum çimlendirilmiştir. Deneyler petri kaplarında ve filtre kağıdında yapılmıştır. Çimşlenme yüzdesi ve hızına bağlı olarak anlamı sonuçlar bulunmuştur p

While almost 600 species of Centaurea L. are common around the world, there are 221 species in Europe. In Turkey, after the genus Astragalus L. and Verbascum L., which includes the most species, Centaurea is the third in terms of the number of species it has. The ratio of endemism is quite high about 63% . In this study, light effects on seed germination of 8 endemic species belonging to Centaurea L. Section Phalolepis Cass. DC. C. cadmea Boiss., C. aphrodisea Boiss., C. amaena Boiss. & Bal., C. lycia Boiss., C. luschaniana Heimerl, C. wagenitzii Hub.-Mor., C. tossiensis Freyn & Sint., C. hieropolitana Boiss. . The effect of light on germination was determined for three photoperiod 16 h light: 8 h dark, 16 h dark: 8 h light, 24 h dark and 25 0C ± 1 temperature regime. In every experiment serie, 100 mature seeds were germinated. Experiments were made in petri disches 9 cm wide and on filter paper. Significant results p
