The Origin of Multiple Macrogametophytes in Poa pratensis
Botanical Gazette, 1946The origin of multiple macrogametophytes in Poa pratensis was studied and the results presented in relation to known breeding behavior of plants from both plural and single embryos. Eggs developed following meiosis may result in haploid-diploid and diploid-diploid relationships in the plural embryos and in the mature plants.

Organization of 5S ribosomal DNA of Poa pratensis L.
Biolohichni systemy, 20205S rDNA, which belongs to the class of repeated sequences, represents a convenient model for studying the molecular evolution of plants. The 5S rDNA repeated unit consists of a conserved region encoding 5S rRNA and variable intergenic spacer (IGS) that contains the motifs required for initiation and termination of transcription.

Growth and nutritive quality of Poa pratensis as influenced by ozone and competition
Environmental Pollution, 2006Interspecific plant competition has been hypothesized to alter effects of early-season ozone (O3) stress. A phytometer-based approach was utilized to investigate O3 effects on growth and nutritive quality of Poa pratensis grown in monoculture and in mixed cultures with four competitor-plant species (Anthoxanthum odoratum, Achillea millefolium, Rumex ...

CHROMOSOME COMPLEMENTS OF FIVE SPECIES OF POA WITH AN ANALYSIS OF VARIATION IN POA PRATENSIS
American Journal of Botany, 1939GRASS INVESTIGATIONS in the past lhave dealt primarily with the taxonomic aspect. Recently, however, turf culture and soil conservation have created a need for a more thorough knowledge of the genetic constitution and interrelationships of the plants employed.

Cytology and Breeding Behavior of Selected Plants of Poa pratensis
Botanical Gazette, 19451. Germination studies carried on in soil in pans, and in a seed germinator, indicated wide average differences among plants of Poa pratensis in the number of seeds set and also in the viability of such seeds. Although germination percentages of a few plants were less than 10%, most plants produced seed of good viability.
