Cyto-Embryological Analysis of Wild Kentucky Bluegrass Germplasm in Gansu Province, China
Agronomy, 2023 Reproduction studies, particularly embryology, represent basic information of any plant. However, the current embryological information is fragmentary for Kentucky bluegrass (Poa pratensis L.).

The evolution of apomixis [PDF]
Heredity, 1981 The selective forces responsible for the evolution of gametophytic apomixis in outbreeding plant populations are analysed in terms of a simple single gene model. In the absence of selection, apomixis inevitably becomes fixed in a population. This conclusion holds regardless of the dominance relations of the alleles specifying apomictic versus sexual ...

Apomixie, sexualité et amélioration des graminées tropicales [PDF]
Tropicultura, 1983 Apomixis, sexuality and improvement of tropical grasses. Gametophytic apomixis together with sexuality can be used for the improvement of tropical grasses. Apomixis is researched for providing an easy spreading of cultivars.

Apomixis in Genista salzmannii DC. (Fabaceae) [PDF]
, 1991 Genista apomixis is described for the first time in two populations of Genista salzmannii DC.: the first is diploid and the second one tetraploid. There was no female meiosis and the megaspore mother cell functioned as an unreduced megaspore, which led ...

BMC Genomics, 2020 Background Paspalum notatum exhibits both sexual and apomictic cytotypes and, thus, is considered a good model for studies of apomixis because it facilitates comparative approaches. In this work, transcriptome sequencing was used to compare contrasting P.

Analysis of variation for apomictic reproduction in diploid Paspalum rufum [PDF]
, 2014 Background and Aims: The diploid cytotype of Paspalum rufum (Poaceae) reproduces sexually and is self-sterile; however, recurrent autopolyploidization through 2n + n fertilization and the ability for reproduction via apomixis have been documented in one ...
