摘要:

Abstract: In the present paper the karyotypes of Smilacina tatsienensis (Franch.) Wang et Tang and Ophiopogon japonicus (L. f.) Ker.- Gawl. in Sichuan were analysed. The karyo- types of the two species are reported for the first time. The results are shown as follows. Smilacina tatsienensis (Franch.) Wang et Tang is a dipoiid. Its karyotype formula is 2n=2x=36=16m+10sm+10st(4SAT) (Plate 1: Fig. 1, 3). The karyotype is bimodal with ten large and eight small chromosome pairs and the length ratio of the tenth pair to the eleventh being 1.33. The length ratio of the largest chromosome and the smallest one is 4.33. Ophiopogon japonicus (L.f.) Ker.-Gawl. is a mixoploid, with diploid, triploid and tetra- ploid cells in a single plant. The karyotype formula of the diploid is 2n=2x=36=18m (4SAT)+18sm(Plate 1: Fig. 2, 4). The species is of a bimodal karyotype with eight large and ten small chromosome pairs and the length ratio to the eighth pair and the ninth being 1.10.There are nine metacentric pairs (two pairs of sat-chromosomes) and nine submetacentric pairs.Decontaminated thianthrene disproportion.
