Germination of Italian Ryegrass Seeds1
Agronomy Journal, 1975AbstractItalian ryegrass (Lolium multiflorum Lam.) is widely planted on western California and Oregon rangelands, but it does not persist or spread. Understanding seed germination characteristics may help to explain its rather poor competitive ability as compared to other naturalized annual grasses.

POST control of Italian ryegrass in hazelnut orchards
Weed Technology, 2021AbstractItalian ryegrass has become a problematic weed in hazelnut orchards of Oregon because of the presence of herbicide-resistant populations. Resistant and multiple-resistant Italian ryegrass populations are now the predominant biotypes in Oregon; there is no information on which herbicides effectively control Italian ryegrass in hazelnut orchards.

Urea application enhances cadmium uptake and accumulation in Italian ryegrass
Environmental Science and Pollution Research, 2020Italian ryegrass (Lolium multifolorum Lam.) has a potential phytoextraction capacity for cadmium (Cd), which is considered as the most toxic heavy metal (HM) pollutant in the farmland. The promotion effect of urea application on Italian ryegrass growth has been clarified, while it is not clear whether and how urea application affects Cd accumulation in

The physiological response to cutting in Italian ryegrass
Grass and Forage Science, 1977AbstractThe kinetics of decline in net photosynthesis and transpiration after cutting was followed in a batch of Lolium multiflorum leaves at light saturation in an assimilation chamber where air temperature, leaf temperature, carbon dioxide concentration and water vapour concentration were controlled.

Somatic hybridisation between common wheat and Italian ryegrass
Plant Science, 2004Abstract Following differing periods of long-term (13 years and 6 years, respectively) subculture and selection, two types of calli of the same wheat (Triticum aestivum L.) cv. Jinan 177 were obtained. The one (named cha9) grew fast and easily formed cell suspensions that were non-regenerable, but the protoplasts possessed a high division capacity ...

Triploid hybrids between Italian and perennial ryegrass
Euphytica, 1975Triploids (2n=21) and aneuploids (2n=19, 20, 22) were obtained through in vitro culture of immature seeds from reciprocal crosses between diploid and tetraploid ryegrass. Tetraploid x diploid crosses were more successful than their reciprocals. Triploids and aneuploids had a high multivalent frequency at meiotic metaphase and were highly vigorous.

PRODUCTIVITY OF ITALIAN AND PERENNIAL RYEGRASS MIXTURES
Grass and Forage Science, 1971ABSTRACTItalian ryegrass cv. Leda and perennial ryegrass cv. Presto were sown alone and in five mixtures containing different proportions of viable seed and compared with hybrid ryegrass cv. Manawa and Italian ryegrass cv. S22. Yields and herbage composition were measured five times in 1962 and 1963, with particular reference to the contribution from ...

Responses of Italian ryegrass to phosphorus on highly‐weathered soils
Journal of the Grassland Society of Southern Africa, 1991Italian ryegrass (Lolium multiflorum cv. Midmar) responses to fertilizer P were studied in field experiments under irrigation on highly-weathered ferrallitic soils at two localities in Natal. Each experiment was conducted over two seasons (1985 and 1986), the pasture being re-established after the first season.

Italian ryegrass for the phytoremediation of solutions polluted with terbuthylazine
Chemosphere, 2015The phytoextraction capacity of Italian ryegrass (Lolium multiflorum L.) to remove terbuthylazine (TBA) from aqueous solution has been assessed using a plant-based biotest (RHIZOtest). Three TBA concentrations (0.5, 1.0 and 2.0 mg L(-1)) were chosen to evaluate the tolerance capacity of the ryegrass.
