[2] [3] It is often called ryegrass, but this term is sometimes used to refer to grasses in other genera. They are characterized by bunch-like growth habits. Lolium is native to Europe , Asia and northern Africa , as well as being cultivated and naturalized in Australia , the Americas , and various oceanic islands.
Perennial ryegrass staggers is poisoning by peramine, lolitrem B, and other toxins that are contained in perennial ryegrass (Lolium perenne), and produced by the endophyte fungus Epichloë festucae which can be present in all parts of the grass plant, but tends to be concentrated in the lower part of the leaf sheaths, the flower stalks and seeds.
Rye (Secale cereale) is a grass grown extensively as a grain, a cover crop and a forage crop. It is grown principally in an area from Eastern and Northern Europe into Russia. It is much more tolerant of cold weather and poor soil than other cereals, making it useful in those regions; its vigorous growth suppresses weeds and provides abundant forage for animals early in the yea
Annual ryegrass toxicity (ARGT) is the poisoning of livestock from toxin contained in bacterially infected annual ryegrass (Lolium rigidum). The toxin is produced by the bacterium Rathayibacter toxicus (formerly Clavibacter toxicus ), which is carried into the ryegrass by the nematode Anguina funesta .
Pythium disease, also known as "Pythium blight," "cottony blight," or "grease spot," is a highly destructive turfgrass disease caused by several different Pythium species. All naturally cultivated cool-season turfgrasses are susceptible to Pythium and if conditions are favorable to Pythium it can destroy a whole turfgrass stand in a few days or less. [1]
The seeds could have been stored at either 1, 3, or 6 months before measuring percentage of germination. At both temperatures of 5 and 20 °C and for only 3 and 6 months of storage for light conditions and at 1, 3, and 6 months of storage for dark conditions, there was a significant increase in the percentage of germination.
Leymus arenarius can grow exponentially in terms of height and root development in the presence of nitrogen.L. arenarius is known to take up nitrogen into its root system. . Increasing nitrogen concentrations can promote growth, as over time, the plant mass above the surface may not change, but nitrogen will accumulate in the root syst
The main compound responsible for the smell of freshly cut grass is cis-3-hexenal. It has a low odour detection threshold that humans can perceive at concentrations as low as 0.25 parts per billion. The compound is highly unstable and breaks down into trans-2-hexenal, [2] which may account for why the smell is said to fade rapidly. [3]
