薰倒牛屬(Biebersteinia)的系統位置及其分類長期存在爭議。本文首次報導了該屬2個種的核形態。染色體間期為簡單型,前期染色體為中間型。薰倒牛(B. heterostemon Maxim.)和羽裂薰倒牛(B. odora Stephan ex Fisch)的核型公式均為2n=10=2m(2sec)+8sm(sec),核型類型屬於3A型。到目前為止,本屬的5個種已有4個種的染色體被計數,其染色體基數可斷定為X=5。該屬具一致的核形態特徵,如染色體間期為簡單型,前期為中間型,在有絲分裂前期和中期,二對染色體具有明顯的4個次縊痕,及3A型的核型,這些均可作為薰倒牛屬的核形態標志。核形態資料不支持把薰倒牛屬放在傳統的擄牛兒苗科(Geraniaceae)中。本屬獨特之核形態以及來自胚胎學、解剖學、化學和分子生物學的證據均支持該屬為一科或目的的等級,至於其系統位置仍需進一步研究。
The systematic and taxonomic position of Biebersteinia Stephan has long been in dispute. The present paper describes for the first time the karyomorphology of two species in Biebersreinia Stephan. Both species commonly showed the interphase nuclei of the simple chromocenter type and the mitotic prophase chromosomes of the interstitial type. The karyotype formulae of both B. heterostemon and B. odora were 2n=10=2m(2sec)+8sm(2sec), belonging to the 3A type of Stebbins' classification. The karyotype of this genus is recorded for the first time. The basic chromosome numbers of four of the five known species of Biebersteinia have been recorded as x=5. The combination of resting nuclei of the simple chromocenter type, mitotic prophase chromosomes of the interstitial type, two pairs of chromosomes with four obvious secondary constrictions at the mitotic prophase and metaphase stages, and the peculiar 3A karyotype in Biebersteinia can be regarded as the karymorphological marker of this genus. The karyomorphological data presented here do not support the traditional grouping of this genus in Geraniaceae. The unique karyomorphology of Biebersteinia justifies its familiar or ordinal status, which is congruent with embryological, anatomical, chemical and molecular data. The systematic position of Biebersteinia needs further study.
