| 英文摘要 | Karyomorphology of five species in Osmunda has been studied. These species are characterized by the complex chromocenter type of the interphase nuclei and the interstitial type of the prophase chromosomes in somatic cells. The condensation pattern of chromosomes in prophase was also observed. The karyotype formulae are as follows: O. banksiifolia (Presl) Kuhn, 2n=4sm+10st+26t+4T; O. japonica Thunb., 2n=2sm+8st+32t (2SAT)+2T; O. vachellii Hook., 2n=4sm+8st+28t+4T; O. angustifolia Ching ex Ching & Ch. H. Wang, 2n=2sm+4st+34t+4T; and O. mildei C. Chr., 2n=2sm+6st+33t+3T. The arm ratios of all the chromosomes are larger than 2, and the karyotypes of the five species are uniform and belong to Stebbins's 4A type. The relationship of karyotype and geographical distribution of three species in the subgen. Plenasium of Osmunda are discussed. The hybrid status of O. mildei is extrapolated from its karyotype and morphology. |
