Lolium perenne, common name perennial ryegrass, [1] English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.
The intradermal allergy test is more sensitive than the skin prick test, but is also more often positive in people that do not have symptoms to that allergen. [ 40 ] Even if a person has negative skin-prick, intradermal and blood tests for allergies, they may still have allergic rhinitis, from a local allergy in the nose.
Nonallergic rhinitis displays symptoms including chronic sneezing or having a congested, drippy nose, without an identified allergic reaction with allergy testing being normal. [1] [2] Other common terms for nonallergic rhinitis are vasomotor rhinitis [3] [4] and perennial rhinitis. The prevalence of nonallergic rhinitis in otolaryngology is 40%.
Ergotism (pron. / ˈ ɜːr ɡ ə t ˌ ɪ z ə m / UR-gət-iz-əm) is the effect of long-term ergot poisoning, traditionally due to the ingestion of the alkaloids produced by the Claviceps purpurea fungus—from the Latin clava "club" or clavus "nail" and -ceps for "head", i.e. the purple club-headed fungus—that infects rye and other cereals, and more recently by the action of a number of ...
The rye was developed by first crossing Secale cereale L. (rye) and Secale montanum (perennial wild rye), then backcrossing the produced F1 generation with Secale cereale L., and selecting for the perennial types. Beneficial characteristics of the crop include early growth in spring, competing well with weeds, and producing significant regrowth ...
Treating allergy symptoms with over-the-counter medication, saline spray, and, if warranted, allergy medication or injections from your doctor, may also help reduce GI symptoms as a result.
Secale montanum, wild perennial rye, is a species in the rye genus Secale native to the Mediterranean, the Middle East, the Caucasus region, and eastwards through Iran to Pakistan. [2] It is a short-lived, self-fertile perennial.
The primary species found worldwide and used both for lawns and as a forage crop is perennial ryegrass (Lolium perenne). Like many cool-season grasses of the Poaceae, it harbors a symbiotic fungal endophyte , either Epichloë or its close relative Neotyphodium , both of which are members of the fungal family Clavicipitaceae .
