Inflorescence to 12 cm long: 8: 8. Synonymy: Not Applicable Common name: None Description: Annuals or perennials; leaf blades flat, usually expanded or folded. Culm-internodes smooth. It is also similar to A. capillaris (p. 639) and A. castellana (p. 639); it differs from both in its longer ligules, from A. capillaris in its less open panicles with spikelets near the base of the branches, and from A. castellana in being more extensively rhizomatous. Spikelets often gaping, with 1 bisexual floret, on slender pedicels, disarticulating above or below the glumes, the spikelets or florets falling from the persistent inflorescence (Agrostis s.

Agrostis capillaris is often referred to in many scientific articles and research as Agrostis tenuis.The accepted name according to ITIS is A. capillaris, while A. tenuis remains a synonym it is commonly found and incorrectly labeled as the primary name (ITIS, 2008).\r\n\r\n.

Anguina agrostis was one of the first plant parasitic nematodes to be taxonomically described by J.G. Panicle oblong to ovate, 1–20 cm long, 1–12 cm wide. Uses. Rhizomes elongated. setifer Spreading Grey-beard Grass The number of galls ranged from 1-24 per 25 g of grass seed (Alderman et al., 2003). Agrostis capillaris (Common Bent-grass) – Inflorescence a finely branched panicle of very small, 1-flowered spikelets and usually flat, glabrous and finely pointed leaf blades and (in A.capillaris) a short ligule, Awns in Agrostis are very variable and an unreliable character for distinguishing species. We advise against extracting comparative information from the descriptions. A. capillaris is highly variable with many cultivars recognised. Inflorescence open, generally oblong to ovate in outline; spikelets not crowded, inflorescence . 1a Malformations of parts above ground => 2. Inflorescence an open or contracted, usually much branched panicle of small spikelets. inflorescence. INTRODUCTION Recent studies indicate that the selection pressures operating in natural populations can be much greater than the nominal values used in early models of natural selection constructed by … Resistance between species and between varieties of the same species of Agrostis varies considerably, however, it is generally accepted that A. tenuis is more susceptible to infection than A. canina or A. stolonifera (Gould et al., 1978; Smith, 1980). As a result, it is not expedient to discriminate the genetic resources of Agrostis capillaris according to geographic criterion.

Tufted, rhizomatous or stoloniferous annuals or perennials. Agrostis (bent or bentgrass) is a large and very nearly cosmopolitan genus of plants in the grass family, found in nearly all the countries in the world.

Inflorescence a loose or contracted panicle, persisting on the culm after maturity (cf. Agrostis capillaris L. APNI* . To examine putative specialization of a hemiparasitic plant to the most beneficial host species, we studied genetic variation in performance and trade‐offs between performance on different host species in the generalist hemiparasite, Rhinanthus serotinus.We grew 25 maternal half‐sib families of the parasite on Agrostis capillaris and Trifolium pratense and without a host in a greenhouse. Some species of bents are commonly used for lawn grass. – Increasingly found naturalised in newly sown road verges, off-ramps and lawns, also in ruderal areas, dumps, coalmine heaps, sand-raised sites, railway yards and other man-made habitats.First reported from Roeselare in 1998 (Lambinon & Verloove 2000).
