    Cytotaxonomical studies on some Crocus L. taxa in Turkey
    Candan, F; Sik, L; Kesercioglu, T
    The present study investigated the chromosome number and morphology of Crocus fleischeri Gay, C. pallasii Goldb subsp. pallasii, C. cancellatus Herbert subsp. lycius Mathew, C. pulchellus Herbert which are all belong to the Crocus L. taxa showing distribution in Western Anatolia in Turkey. Powder preparation was used as study method. Chromosome numbers and morphologies of the taxa were determined by examining the mitosis preparations. Furthermore, karyograms of taxa studied were made and examined in a detailed manner. In this study, it was found that the chromosome numbers of C. fleischeri, C. pallasii subsp. pallasii, C. cancellatus subsp. lycius and C. pulchellus were 2n = 20, 2n = 14, 2n = 16 and 2n = 12, respectively.

    Chromosome numbers of two Colchicum L. species, C. burttii and C. balansae, from Turkey
    Sik, L; Kesercioglu, T; Candan, F
    Chromosome numbers and morphologies for Colchicum burttii Meikle and Colchicum balansae Planchon showing distribution in western Anatolia were studied. Squashing preparation method was used. The chromosome counting and morphologies of the species were determined by examining the mitosis prepared from root tips of plants. Chromosome number of C. burttii is 2n = 60 + 2B, showing that this species is hexaploid (x = 10). On the other hand, chromosome number of C. balansae is found as 2n = 90. Formerly, chromosome number of this species was reported as 2n = 32, 54 and 108. In conclusion, chromosome number of the sample obtained with this investigation is different from previous studies. 2n = 90 chromosome number is a basic polyploid (hexaploid) with x(2) = 15 (15*6 = 90), involving the summation of the primary basic numbers, 7 and 8.
