Morphological, cytological and field observations on 20 populations of theAgrostis mertensii-flaccida complex were reported. The plants were found to be diploid, tetraploid, hexaploid, septaploid or octoploid with a basic chromosome number of x=7. The diploids were most wide-spread and diverse in habitat and morphology. The tetraploids were discovered in 3 sites in Hokkaido. The hexaploids and octoploids occurred on various mountains in central and northern Honshu as well as in some of Hokkaido… Expand

Agrostis mertensii (Poaceae) in hokkaido
A conclusion was drawn that the hexaploid plant of Hokkaido should be grouped with the octoploid in one and the same species, Agrostis mertensii Trin. Expand

The extensive aneuploidy in Sedum aizoon L. var.aizoon seems to be caused by the unequal chromosome segregation in meiosis and the subsequent fertilization of gametes with various chromosome numbers. Expand
Polyploidy in agriculture: With special reference to mulberry
The mulberry is an economically important crop, cultivated for its foliage to rear the silkworm Bombyx mori L. Its chromosome number varies from 2n = 28 to 2n = 308 with ploidy level from x to 22x.Expand


Karyotaxonomy in Poaceae
Somatic chromosomes of sixty eight species found in Japan and in some foreign countries were reported and karyotaxonomic information concerning the genus Brachyelytrum was mentioned. Expand
Species differentiation inAgrostis
The cytological analysis of this material leads to a fuller understanding of the nature of the three species of Agrostis, and particularly with the tetraptoid hybrids. Expand
Species differentiation inagrostis
The present paper and those which follow elucidate some of the problems of species differentiation by a study of the chromosomes at meiosis in the British species and their hybrids. Expand
Differentiation of populations.
It is argued that selection is both the primary cohesive and disruptive force in evolution, and that the selective regime itself determines what influence gene flow (or isolation) will have. Expand
