禾本科牧草数種の核型分柝

抄録

1) The chromosome numbers and morphologies were studied in the species of Lolium, one species of Arrhenatherum and one species of Sorghum.
2) The karyotype formulae were as follows:
Lolium perenne K(2n)=14=2A^m₁+2_csA^sm₂+2B^m₁+2_csB^sm₂+2C^sm₁+2C^st₂+1C^st₃
L. multiflorum ^K2(ⁿ)=14=2A^sm₁+2_csA^sm₂+2B^m₁+2B^sm₂++2_csB^sm₃+2C^sm₁+2C^st₁
L. temulentumK(2n)=14=2A^m₁+2A^sm₂+2A^st₃+2A^m₄+2B^sm₁+2B^st₂+2C^m₁
