Karyotypes of the Genus Fritillaria from South Anhui

This paper reports chromosome numbers and karyotypes of five species of the genus Fritillaria from south Anhui. The origin of the material used in this work is provided in Table 1, micrographs of mitotic metaphase in Plate 1,2, and the parameters of chromosomes in Table 2. Except F. thunbergii Miq., the karyotypes and chromosome numbers of all the species in this paper were studied for the first time. The results are shown as follows: 1. Fritillaria qimenensis D. C. Zhang et J. Z. Shao Collected from Qimen, Anhui, it has the karyotype formula 2n = 24+4Bs = 3m+lsm+8st (2sc)+12t (2sc)+4Bs (Plate 1:1, 2). The chromosomes range in length 8.72-19.13μm, with the ratio of the longest to the shortest 2.19. Therefore, the karyotype belongs to Stebbins’ (1971) 3B. The secondary constrictions are found on the long arms of 7th and 10th pairs. All the five B-chromosomes are of terminal centromeres. The two chromosomes of the second pair show heteromorphy (Fig. 1, E) with arm ratios 1.86 and 1.56 respectively. 2. Fritillaria monantha Miq. var. tonglingensis S. C. Chen et S. F. Yin Collected from Tongling, Anhui, this species is shown to have three chromosome numbers, 2n =24+5Bs, 2n=24+2Bs and 2n=24. This paper reports 2 cytotypes: Type I: 2n = 24+5Bs = 4m+8st (2sc) +12t (2sc) +5Bs (Plate 1: 3, 4). The chromosomes range in length from 10.40 to 22.19μm, with the ratio of the longest to the shortest 2.13. It belongs to 3B of stebbins’(1971) karyotypic symmetry. The secondary constrictions are found on the short arms of 7th and the long arms of 9th chromosome pairs. The metacentric B-chromosomes and the small satellites located on the short arms are major characters of this cytotype. Type II: 2n=24=2m+2sm+8st(2sc)+12t(2sc) (Plate 1:5, 6). The chromosomes range in length from 13.84 to 29.81μm, with the ratio of the longest to the shortest 2.15. The karyotype belongs to Stebbins’3B. The secondary constrictions are found on the long arms of 5th and 10th pairs. No B-chromosomes are found. 3. Fritillaria xiaobeimu Y. K. Yang, J. Z. Shao et M. M. Fang Collected from Ningguo, Anhui, it has karyotype formula 2n = 24 = 2m+2sm+10st (4sc) + 10t (Plate 2:7, 8). The chromosomes range in length from 13.86 to 26.27μm, with the ratio of the longest to the shortest 1.89. The karyotype belongs to stebbins’3A. The secondary constrictions are found on the long arms of 7th and 9th pairs. 4. Fritillaria ningguoensis S. C. Chen et S. F. Yin Collected from Ningguo, Anhui, it is of karyotype formula 2n = 24 = 2m+2sm+8st (2sc) +12t (Plate 2: 9, 10). The chromosomes range in length from 9.11 to 23.23μm, with the ratio of the longest to the shortest 2.55. The karyotype belongs to Stebbins’3B. The secondary constrictions are only found on the long arms of the 10 th pair. 5. Fritillaria thunbergii Miq. Collected from Ningguo, Anhui, it is of karyotype formula 2n = 24 = 2m+2sm+8st(2sc) +12t(2sc)(Plate 2:11, 12). The chromosomes range in length from 8.83 to 19.85μm, with the ratio of the longest to the shortest 2.25. The karyotype belongs to stebbins’3B. There are secondary constrictions on the long arms of 5th and 7th pairs. The karyotype of the Ningguo material is similar to that of the Huoqiu (Anhui) material reported by Xu Jin-lin et al. (1987), but it is obviously different from 2n=2m(sc)+2sm+4st(2sc)+16t (2sc) reported byZhai et al. (1985) for the material from Xingjiang, Northwest China.     

Karyotype Analysis of Eight Species of Polygonatum Mill.

Meiosis and mitosis of eight species of Polygonatum from Sichuan, China, were investigated. Ten bivalents (n=10) at meiosis of pollen mother cells were observed ih P. odoratum (Mill.) Druce. Meiotic observation on pollen mother cells in P. punctatum Royle ex Kunth shows 16 bivalents (n=16) at diakinesis, P. kingianum Coll. et Hemsl. 13 bivalents (n=13) at diakinesis. P. zanlanscianense Pamp. 15 bivalents (n=15) in MI, P. cirrhifolium (Wall.) Royle 28 bivalents at diakinesis. Somatic chromosomes were observed in root tip cells. The karyotype formulae are as follows: P. odoratum (Mill.) Druce K(2n)=20=4st+6sm+10m; P. cyrtonema Hua K(2n)=20=6sm+14m; P. punctatum Royle ex Kunth K(2n)=32=2t+8st+ 2sm+20m; P. kingianum Coll. et Hemsl. K(2n)=26=8st(2SAT)+14sm+4m; P. alternicirrhosum Hand.-Mzt. K(2n)=32=6st+8sm+18m(2SAT); P. zanlanscianense Pamp. K(2n)=30= 2t+6st+6sm+16m(2SAT); P. sibiricum Delar. ex Redouté K(2n)=24=2t+14st(2SAT)+6sm +2m; P. cirrhifolium (Wall.) Royle K(2n)=56=18st+10sm+28m. The karyotypes of P. punctatum, P. kingianum, P. alternicirrhosum and P. cirrhifolium are reported for the first time. Both the chromosome number and structure in our materials are certainly different from thoses in previous reports. Of numerical variation polyploidy and aneuploidy have been recorded, and aneuploidy is frequent. According to degree of asymmetry of the karyotype, the 8 species are divided into three types: 2B, 3B, 2C. The increasing asymmetry is correlated with the increasing of the chromosome number. There are no obvious differences in chromosome number and karyotype between Alternifolia Baker and Verticillate Baker. They are not two natural groups. This opinion is different from that of Therman and Suomalainen.     

黄精属细胞分类学研究Ⅱ.四川金佛山地区黄精属植物核型

本文对四川金佛山地区4种黄精属植物的核型进行了研究,其结果为:滇黄精:2n=26=6m+12sm(2SAT)+8st(2SAT);距药黄精:2n=26=10m+4sm+12st;垂叶黄精:2n=30=14m(2SAT)+4sm+10st+2t、2n=28=14m+6sm+6st+2t;湖北黄精:2n=30=12m+8sm+10st、2n=28=6m+10sm+10st+2t、2n=22=2m+12sm 8st。通过与其它地区黄精属植物染色体数目与形态的比较,发现本地区所有种类的染色体数目普遍偏高,无论在染色体基数或染色体形态上都比较接近喜马拉雅山地区分布的种类。从实验结果进一步看出了黄精属的染色体变异是相当明显的,并主要表现为非整倍性变异;在有些情况下,染色体数目与结构的变异能与某些形态学特征相联系。     

锦鸡儿属植物一些种类的染色体数目及核型研究

报道了国产10种锦鸡儿的染色体数目,并对其中9种的核型进行了研究。这9个种的核型公式分别为：荒漠锦鸡儿（Caragana roborovskyi）,2n＝16＝10m(2SAT)+6sm;川西锦鸡儿（C. erinacea）,2n=16=10m+6sm;密叶锦鸡儿（C. densa）,2n=16=10m（2SAT）+6sm;刺叶锦鸡儿（C. acanthophylla）,2n=16=12m+4sm;柄荚锦鸡儿（C. stipitata）,2n=16=10m+6sm;甘蒙锦鸡儿（C. opulens）,2n=16=12m(2SAT)+4sm;白皮锦鸡儿（C. leucophloea）,2n=32=22m(4SAT)＋10sm;北疆锦鸡儿（C. camilli-schneideri）,2n=32=20m(4SAT)+12sm;中亚锦鸡儿（C. tragacanthoides）,2n=32=20m(2SAT)+10sm+2st+2B。白毛锦鸡儿（C.licentiana）2个居群的染色体数目均为2n=32,为四倍体。研究结果表明,锦鸡儿属的核型一般比较对称,核型上的特化往往与其形态上的特化相关联,但也有例外。从倍性水平上来看,二倍体类群多是一些羽状叶的种,在分布上倾向于亚洲东部其祖先分布区,而四倍体的种类多是一些假掌状叶的类群,分布于西部干旱生境中,在形态上也表现的较为特化。这也符合锦鸡儿属的演化趋势。
