Abstract

The present study details chromosome features and new record for nine Cyperaceae species from Thailand, namely Fimbristylis dichomata (L.) Vahl., F. miliacea (L.) Vahl., Rhynchospora chinensis Nees & Mey., R. corymbosa (L.) Britton., Cyperus compactus Retz., C. corymbosus Rottb., C. involucratus Roxb., C. iria L. and C. laxus Lam. var. laxus. Chromosome numbers for F. miliacea (L.) Vahl., C. compactus Retz., C. involucratus Roxb., C. iria L. and C. laxus Lam. var. laxus. Whereas, new numbers are reported for all these species, and for C. laxus this is the first report on its chromosome number. The somatic numbers range from 10 to 120 showing dysploidy. The study provides karyomorphological details of the examined species vis-à-vis published records. The karyotype and idiogram analysis reveal asymmetrical karyotypes falling into 1C and 2C categories, constituted by metacentric (m), submetacentric (sm), subtelocentric (st), acrocentric (a) and telocentric (t) karyomorphology. The karyotype formulae for species described here are : 2n (28) = 16 m + 2sm + 4st + 6t; 2n (20) = 2 m + 16sm + 2t; 2n (10) = 6 m + 4sm and 2n (10) = 4sm + 4st + 2t for F. dichomata (L.) Vahl.; F. miliacea (L.) Vahl., R. chinensis Nees & Mey. and R. corymbosa (L.) Britton, respectively. Our results expand the information related to chromosome rearrangements in karyotype differentiation in representative taxa of Cyperaceae.
