摘要
本文报道10种国产石斛属(Dendrobium)植物的染色体研究结果。它们的染色体均属小型染色体,长度为1—3.47μm.染色体数皆为2n=38。其中有6种和国内外报道的结果相同,有4种为首次报道。
The chromosome number (2n=38) of 10 species in Dendrobium from China are recorded in the present paper. Their chromosomes are all microchromosomes (1—3.7μm). Among which the chromosome numbers of 6 species (D. crepidatum Lindl et Paxt; D. denneanum Kerr; D. lohohense Tang et Wang; D. moniliforme (L.) Sw.; D. nobile Lindl and D. hercoglossum Rchb. f.) had been reported on the chromosome numbers, 4 species (D. crispulum kimura et Migo; D. fimbriatum Hook; D. jenkinsii wall et Lindl; D. officinale Kimura et Migo) are reported for the first time.
