Cytology and reproductive behavior of hybrids between Paspalum urviUei and two hexaploid P. dilatatum biotypes
Sexual, tetraploid (2n = 4x = 40) vaseygrass (Paspalum urvillei Steud.) was crossed with two apomictic, hexaploid (2n = 6x = 60) dallisgrass (P. dilatatum Poir.) biotypes (Uruguayan and Uruguaiana) to determine their relationships and the reproductive behavior of the hybrids. One vaseygrass x Uruguayan and two vaseygrass x Uruguaiana hybrids were studied and all had 2n = 5x = 50 chromosomes. Th...
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-...
متن کاملFirst Italian record of Paspalum notatum Flüggé (Poaceae) and its typifi cation
In the present work the presence of Paspalum notatum Flüggé (Poaceae) in Italy was reported for the fi rst time. It is a neophyte native to America, known for applications in phytoremediation. Its typifi cation, ecology and invasiveness status are also presented.
متن کاملPHYLLOCHRON 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 کاملLinking Management, Environment and Morphogenetic and Structural Components of a Sward for Simulating Tiller Density Dynamics in Bahiagrass (Paspalum notatum)
A model which describes tiller density dynamics in bahiagrass (Paspalum notatum Flügge) swards has been developed. The model incorporates interrelationships between various morphogenetic and structural components of the sward and uses the inverse of the self-thinning rule as the standard relationship between tiller density and tiller weight (a density-size equilibrium) toward which tiller densi...
