Cyto-Embryological Analysis of Wild Kentucky Bluegrass Germplasm in Gansu Province, China
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]
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 ...

Abstract Cultivation as a summer annual grass in temperate regions of new extremely late‐maturing guineagrass cultivar “Umaku” without heading with fertilizer application entails risks of toxic nitrate nitrogen (nitrate‐N) concentration in the grass.

Apomixie, sexualité et amélioration des graminées tropicales [PDF]
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.

Reproduction - a factor of plant evolution
The process of reproduction (amphimixis and apomixis) represents a major factor of evolution. The facultative apomictic species are the pioneers of evolution.

Apomixis in Genista salzmannii DC. (Fabaceae) [PDF]
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 ...

Ploidy levels and reproductive behaviour in invasive Hieracium pilosella in Patagonia [PDF]
Within a population of invasive Hieracium pilosella in Chilean Patagonia we found two ploidy levels, pentaploid and hexaploid. Each ploidy level was represented by one clone.
