摘要

对分布在土耳其的鸢尾属5种植物的染色体数目和核型进行了分析。这些分类群分别是I. aucheri (Baker) Sealy, I. reticulata var. reticulata M. Bieb。， I.佩尔西卡L.， I.佩什梅尼亚·格尔纳& T.霍尔，I.萨里·肖特前贝克。其中两种(I. sari和I. peshmeniana)是土耳其的地方病。所研究的分类群染色体数分别为:2 n =18(桃属)、2 n =20(沙属)、2 n =24(桃属)和2 n =36(网属)。单倍体染色体长度在不同种属间从53.45µm到130.78µm不等。核型分析表明，鸢尾类群一般有中位(m)、亚中位(sm)和亚端(st)染色体。此外，只有沙丽有两条末端(T)染色体。首次测定了白桦的核型。

Karyotype Analysis of Five Iris L. (Iridaceae) Species from Turkey

Summary The chromosome numbers and karyotypes of ﬁve species of the genus Iris distributed in Turkey were analyzed. These taxa are I. aucheri (Baker) Sealy, I. reticulata var. reticulata M. Bieb., I. persica L., I. peshmeniana Güner & T. Hall, I. sarii Schott ex Baker. Two of them ( I. sari and I. peshmeniana ) are endemic in Turkey. The chromosome numbers of studied taxa were determeined as 2 n =18 ( I. persica ), 2 n =20 ( I. sari ), 2 n =24 ( I. peshmeniana and I. aucheri ), and 2 n =36 ( I. reticulata var. reticulata ). Haploid chromosome lengths varied from 53.45 µ m ( I. persica ) to 130.78 µ m ( I. reticulata var. reticulata ) among species. Karyotype analysis indicated that Iris taxa generally have median (m), submedian (sm), and subterminal (st) chromosomes. In addi-tion, only I. sari has two terminal (T) chromosome pairs. The karyotype of I. peshmeniana was determined for the ﬁrst time.
