Abstract

JARA-SEGUEL, Pedro; ROMERO-MIERES, Mario  and  PALMA-ROJAS, Claudio. CHROMOSOME NUMBERS OF CHILEAN PTERIDOPHYTES: FIRST CONTRIBUTION. Gayana Bot. [online]. 2006, vol.63, n.1, pp.115-118. ISSN 0016-5301.  http://dx.doi.org/10.4067/S0717-66432006000100007.

Mitotic chromosome counts in Chilean pteridophytes confirm the diploidy described for Equisetum L. (2n = 216) and Blechnum L. (2n = 66), as well as the tetraploidy of Asplenium L. (2n = 144). Megalastrum spectabile (Kaulf.) A.R.Sm. et R.C.Moran is diploid (2n = 82), while in metaphases of Polystichum subintegerrimum (Hook. et Arn.) R.A.Rodr. chromosome numbers from ca. 311 to 328 were counted. Tetraploidy was also described in Adiantum chilense Kaulf. (2n = 116)
