Multivariate analysis reveals genetic diversity in Paspalum notatum Flügge
نویسندگان
چکیده
The objective of this study was to evaluate 94 Paspalum notatum genotypes over two growing seasons estimate genetic dissimilarity through agronomic traits and the distance between genotypes. This information is used create an ideotype from best averages obtained for set characteristics evaluated. Seven apomitic, three sexual, 81 hybrid were compared with native “André da Rocha”, “Bagual”, cultivar “Pensacola” as controls. There variability in P. studied [...]

PHYLLOCHRON OF Paspalum notatum FL. AND Coelorhachis selloana (HACK.) CAMUS IN NATURAL PASTURE
Leaf appearance rate and phyllochron are related variables which play a central role in forage production. Phyllochron is the time interval between the appearance of successive leaves and varies according to a number of environmental factors, among which temperature is the most important. The experiment was conducted in natural pasture with the aim of testing phyllochron variation under differe...
متن کاملMeta-analysis reveals lower genetic diversity in overfished populations.
While population declines can drive the loss of genetic diversity under some circumstances, it has been unclear whether this loss is a general consequence of overharvest in highly abundant marine fishes. We compiled data from 11 049 loci across 140 species and found that allelic richness was lower in overfished populations within 9 of 12 genera and families. A multiple linear regression showed ...

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Sequence characterization, in silico mapping and cytosine methylation analysis of markers linked to apospory in Paspalum notatum
In previous studies we reported the identification of several AFLP, RAPD and RFLP molecular markers linked to apospory in Paspalum notatum. The objective of this work was to sequence these markers, obtain their flanking regions by chromosome walking and perform an in silico mapping analysis in rice and maize. The methylation status of two apospory-related sequences was also assessed using methy...
متن کاملYield and quality characteristics of bahiagrass (Paspalum notatum) exposed to ground-level ozone
Early and late season-planted bahiagrass (Paspalum notatum Flugge, cultivar `Pensacola') were grown in open-top chambers (OTC) to which added air had been carbon-®ltered (CF), representative of that found at pristine air quality sites; non-®ltered (NF), characteristic of ambient air in Auburn, AL and representative of that found in rural agricultural areas; or enriched with ozone (O3) to twice-...
