四川当归属六种植物的核型

从居群水平对四川当归属(AngelicaL.)6种植物的核型进行了研究,其中管鞘当归核型为首次报道。6个种的染色体均为2n=2x=22,多为中部和近中部着丝粒染色体,核型多为2A型,仅疏叶当归石灰窑居群为1A型;峨眉当归核型为2n=22=10m 2sm 10st,茂汶当归核型为2n=22=16m 4sm 2sm(SAT),当归核型为2n=22=14m 8sm,阿坝当归核型为2n=22=14m 8sm,管鞘当归核型为2n=22=12m 8sm 2sm(SAT),而疏叶当归不同居群的核型或多或少发生了不同程度的变异。参照Stebbins的观点,峨眉当归以核型不对称系数最高而在6个种中显示一定的核型进化性,疏叶当归不对称系数较低,且出现1A型核型因而体现出一定的原始性。但是,综合形态解剖、花粉性状以及核型特征可以看出,四川当归属植物各性状间具有进化的不同步性,这也表明,作为当归属分布频度中心之一的四川地区,同时也是当归属的分化中心之一。     

A Study on Karyotypes of Eight Species and Geographical Distribution of Angelica (Umbelliferae) in Sichuan

Nearly 32 species of Angelica occur in China, taking up one third of total species number of the genus in the world, with 12 species in Sichuan. In the present paper karyotypes of 8 species from Sichuan are first reported with x = 11. The parameters of chromosomes of 8 species are given in Table 1 and the karyotypes are shown in Plate 1, 2. The karyotype formulae are as follows: A. valida Diels K(2n) =22=20m+2sm (Wulong Xian, alt. 1900m); A. dielsii Boiss. K(2n) =22= 18m+2sm^sat+2sm (Songpan Xian, alt. 3000m); A. laxifoliata Diels has 2 kinds of karyotypes in 3 populations: K(2n) =22= 18m+4sm (Hanyuan Xian, alt. 1900m) and K(2n) =22= 16m+6sm (Songpan Xian, alt. 2500m and Baoji in Shaanxi, alt. = 1500m); A. setchuensis Diels K (2n) = 22 = 16m+2sm^sat+4sm (Songpan Xian, alt. 2800m); A. maowenensis Yuan et Shan K(2n) =22= 16m+ 6sm (Songpan Xian, alt. 2800); A. chinghaiensis Shan ex K.T.Fu K (2n) = 4x= 44 = 36m+8sm (Songpan Xian, alt. 3500m); A. Sinensis (Oliv.)Diels K(2n) =22= 14M+8sm (Songpan Xian, alt. 2900m); A. omeiensis Yuan et Shan K (2n) = 22 = 10m+2sm+ 10st (Mt. Omei, alt. 2100m). The karyotypes of A. valida and 2 populations of A. laxifoliata belong to “1A” and those of one population of A. laxifoliata and the rest 6 species “2A”. By analysing the correlation between the karyotypic symmetry and vertical distribution of A. laxifoliata and A. chinghaiensis, it is considered that as altitude rises, the karyotypic asymmetry and ploidy increases. Comparing with the karyotypes of other species distributed in Northeastern China and Japan previously reported, the karyotype of A. valida with oblong-ovoid fruits and 1-2-pinnate leaves is most primitive and that of A. omeiensis with nearly rounded fruits and 3-ternate-pinnate leaves is most advanced in Angelica. Based on the fact that many species including the most primitive and the most advanced species are concentrated in Sichuan, it may be suggested that the center of origin and diversity of Angelica be inSichuan characterized.

报道了国产赖草属５个种的核型,即大赖草,２ｎ＝４ｘ＝２８＝２４ｍ（２ＳＡＴ）＋４ｓｍ（２ＳＡＴ）;粗穗赖草２ｎ＝４ｘ＝２８＝２２ｍ（２ＳＡＴ）＋４ｓｍ＋２ｓｔ（２ＳＡＴ）;若羌赖草,２ｎ＝４ｘ＝２８＝２０ｍ（４ＳＡＴ）＋６ｓｍ＋２ｓｔ（２ＳＡＴ）;羊草,２ｎ＝４ｘ＝２８＝２２ｍ（４ＳＡＴ）＋２ｓｍ＋４ｓｔ（４ＳＡＴ）;窄颖赖草,２ｎ＝４ｘ＝２８＝２２ｍ（２ＳＡＴ）＋４ｓｍ（２ＳＡＴ）＋２ｓｔ（２Ｓ     

鹅观草属五个类群的核型与进化

报道了鹅观草属５个类群的核型,即长芒鹅观草,核型２ｎ＝４ｘ＝２８＝２２ｍ＋６ｓｍ（２ＳＡＴ）;短颖鹅观草,核型２ｎ＝４ｘ＝２８＝２０ｍ（２ＳＡＴ）＋８ｓｍ（２ＳＡＴ）;短柄鹅观草,核型２ｎ＝４ｘ＝２８＝２２ｍ（２ＳＡＴ）＋６ｓｍ;纤毛鹅观草,核型２ｎ＝４ｘ＝２８＝２０ｍ＋８ｓｍ（４ＳＡＴ）;毛盘鹅观草,核型２ｎ＝４ｘ＝２８＝１８ｍ＋６ｓｍ（４ＳＡＴ）＋４ｓｔ。同时,通过核型重要性状的递变分析,揭示了鹅观草属５个类群的相对进化程度以及宏观分类中４个组的系统发育关系,表明鹅观草属的半颖组在系统发育中可能既派生了颖体短小的小颖组,又派生了颖体长大的大颖组和长颖组。     

鹅观草属4个种核型与进化的研究

报道了鹅观草属(Roegneria C. Koch)4个种的核型,即中华鹅观草,核型为2n=4x=28=28m(2SAT);裸穗鹅观草,核型为2n=4x=28=24m+4sm(2SAT);缘毛鹅观草,核型为2n=4x=28=22m+6sm(2SAT);缘穗鹅观草,核型为2n=4x=28=24m(2SAT)+4sm。4个种核型的共征和自征反映了形态划分中共属分种的合理性。尤其通过核型不对称性和相对进化程度的分析,表明中华鹅观草最原始,缘穗鹅观草最进化,裸穗鹅观草和缘毛鹅观草演化居中;狭颖草系高级于缘毛草系。核型不对称性所表示的进化程度似乎与系间颖芒的发生,种间花序的增长变粗、外稃芒的延伸相关。

Cytotaxonomy of Ferula L. in China

The karyotypes of somatic cells of three species in Ferula L. (Umbelliferae) from China are reported for the first time in this paper. F. licentiana Hand. -Mazz., endemic to China, has the karyotype formula of 2n= 22= 14m+ 2sm+ 6st( 2SAT), which consists of nine pairs of L chromosomes (the relative length > 8.0) and two pairs of M chromosomes (the relative length, 8.0- 6.0). The index of the karyotypic asymmetry (AS. K%) is 36.36%, and the karyotype belongs to 2A (Stebbins 1971). F. licentiana var. tunshanica (Su) Shan et Q. X. Liu has the karyotypic formula of 2n=22= 14m+ 8st(2SAT), and the other characters of karyotype are very similar to those of F. licentiana. The karyotypic formula of F. bungeana Kitag. is 2n=22= 12m+ 6sm+ 2st. There are 8 pairs of L chromosomes and 3 pairs of M chromosomes in this karyotype. The AS.K% is 45.45% and thus the karyotype is rather symmetrical (2A). Based on above data, F.licentiana var. tunshanica may be treated as a variety of F.licentiana and F.bungeana be separated from Subgen. Peucedanoides. According to our study and available data, we consider that the basic chromosome number of Ferula is x= 11. The karyotypic evolution of 11 species in the genus from China is analysed. All species are grouped into 5 groups based on the cluster analysis of chromosome data: I.F. akitschensis B. Fedtsch. ex K.-Pol.; II. F. lapidosa Korov., III. F. bungeana. The above-mentioned three species belong to Subgen. Peucedanoides in classification. IV. This group is divided into two subgroups: (1) F. syreitschikowii K.-Pol. and F. ovina (Boiss.) Boiss.; (2) F. lehmannii Boiss., F. licentiana, F. licentiana var. tunshanica, F. Kirialovii Pimen. and F. sumbul (Kauffm.)Hook. f., in which F.lehmannii belongs to Subgen. Merwia, F. syteritschikowii to Subgen. Narthex and the rest five species to Subgen.Peucedanoides. V. F.caspica M. Bieb. of Subgen. Doromatoides.

沙冬青属(Ammopiptanthus)植物仅两个种,即蒙古沙冬青(A.mongolicus)和新疆沙冬青(A.nanus),为第三纪残遗种,是中亚荒漠唯一的常绿阔叶植物,因珍稀,临危而被列为国家重点保护植物”。国内外对该属两个种的染色体数目的记载存在着差异。本文对沙冬青属两种植物的染色体数目和核型进行了分析研究,旨在为探讨该属植物的发生和系统发育,以及开展植物多样性保护和合理开发利用积累资料。     

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.

The Studies on the Karyotypes and Cytogeography of Taxodium Rich.(Taxodiaceae)

The present paper deals with the karyotypic analysis of Taxodium ascendens Brongn. The somatic chromosomes in root-tip cells of the plant are found to be 2n =22, all with median and submedian constrictions. A character of the karyotype is that the chromosome 10 has a long kinetochore region (Plate 1:1). According to the terminology defined by Levan et al.^[18], the karyotype formula is k(2n)=22=20m+2sm, which is different to Huang et Hsu’s^[8] K(2n)=24=22m+2B(m). The karyotype belongs to “lA” of Stebbins’^[24] karyotypic symmetry and is generally regarded as a relatively primitive one. The species’ chromosome complement is 2n=22=2L+8M₂+12M₁ according to I.R.L.difined by Kuo et al.^[15] based on relative length. The lengths, arm ratios and types of chromosomes of the species are given in Table 1-I. The morphology of the chromosomes and the karyotype, are given in Plate 1:1. In the light of the works of Schlarbaum et al.^[21] and Mehra et al.^[17], K(2n)=22=20m (2SAT)+2sm and 2n=22=2L+6M₂+14M₁ are for T. distichum (L.) Rich. (see Table 1-II), K(2n)=20m+2sm and 2n=22=4L+4M₂+12M₁+2S for T. mucronatum Tenore (see Table 1-III, Plate 1:2), which belong to “lA” and “2A” respectively. The differences between three species in the ratio of the longest to the shortest chromosome, I.R.L. and the proportion of chromosomes with arm ratio >2 show that the karyotype of T. mucronatum is the most advanced and that of T. distichum the most primitive. The present author suggests that the sequence of evolutionary advance be T. distichum, T. ascendens, T. mucronatum. Based on the evidence from the karyotype analyses, ecology and geographical distribution (including fossil), the secondary center of genetic diversity (Fig. 1) and the probable evolu-tionary pattern (Fig. 2) of Taxodium are discussed.     

青藏高原毛茛科3种特有植物核型和进化研究

对青藏高原高山冰缘地区毛茛科３种特有植物的核型进行了分析。它们的核型公式（Ｋ）、染色体相对长度组成（Ｃ．Ｒ．Ｌ．）和核型不对称系数（Ａｓ．Ｋ％）分别为：青藏金莲花Ｔｒｏｌｉｕｓｐｕｍｉｌｕｓｖａｒ．ｔａｎｇｕｔｉｃｕｓ：Ｋ（２ｎ）＝６ｍ＋８ｓｍ（２ＳＡＴ）＋２ｓｔ,Ｃ．Ｒ．Ｌ．＝４Ｌ＋４Ｍ２＋４Ｍ１＋４Ｓ,Ａｓ．Ｋ％＝６３．５７,核型属２Ｂ型;甘青乌头Ａｃｏｎｉｔｕｍｔａｎｇｕｔｉｃｕｍ为Ｋ（２ｎ）＝６ｍ＋１０ｓｍ,Ｃ．Ｒ．Ｌ．＝４Ｌ＋８Ｍ１＋４Ｓ,Ａｓ．Ｋ％＝６２．５４,２Ｂ型;单花翠雀花Ｄｅｌｐｈｉｎｉｕｍｃａｎｄｅｌａｂｒｕｍｖａｒ．ｍｏｎａｎｔｈｕｍ为Ｋ（２ｎ）＝６ｍ＋８ｓｍ＋２ｓｔ,Ｃ．Ｒ．Ｌ．＝４Ｌ＋４Ｍ２＋４Ｍ１＋６Ｓ,Ａｓ．Ｋ％＝６４．３４,属３Ｂ型。经同相关近缘种核型资料比较,青藏金莲花核型不对称性和进化程度比金莲花Ｔ．ｃｈｉｎｅｎｓｉｓ低;甘青乌头的核型不对称性和进化程度在其近缘类群（乌头组Ｓｅｃｔ．Ａｃｏｎｉｔｕｍ）已报道的种之内最低;单花翠雀花核型不对称性和进化水平比翠雀组（Ｓｅｃｔ．Ｄｅｌｐｈｉｎａｓｔｒｕｍ）已报道的展毛翠雀花Ｄ．ｋａｍａｏｅｎｓｅｖａｒ．ｇｌａｂｒｅｓｃｅｎｓ、
