Chromosome Numbers in Eleven New Hemarthria (Limpograss) Introductions
1972
Schank, S. C.
Chromosome counts, pollen stainability, and seed-setting ability are presented for 10 new Hemarthria altissima (Poir.) Stapf et C. E. Hubb accessions from Africa and one native Hemarthria sp. from Argentina. Root tip smears confirmed that the basic chromosome number of this genus is x = 9. Nine of the introductions are diploid, 2n = 18, and two are tetraploid, 2n = 36. Pollen stainability and seed set indicate that all 11 introductions may be included in an intrageneric breeding program.
