Pl. For many plants, the website displays maps showing physiographic provinces within the Carolinas and Georgia where the plant has been documented. 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). The diffuse inflorescence breaks away at maturity and can be dispersed over long distances by wind . Hair-grass Allium triquetrum Three-cornered Garlic Allocasuarina muelleriana ssp. Sheaths smooth and rounded on the back; ligule truncate or rounded, c. 1 mm long; blade flat, 1–17 cm long, 1–5 mm wide. Subject: Life Sciences GET ALERTS DONATE. Journal of Nematology. It has been bred as a GMO creeping bent grass. 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. However, the averaged values of the tested traits did not significantly differ between the countries, except for the inflorescence emergence date.

At some sites Agrostis capillaris was a minor component of otherwise indigenous vegetation; other sites were extensively modified. Rhizomes elongated. Inflorescence branches: Ventenata dubia (North Africa grass); Vententata colonizes disturbed sites in open dry areas. 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.

Key words: Agrostis capillaris L., copper tolerance, competition. Glumes similar, firmer than fertile lemma, shiny. Agrostis capillaris: Common Bent: Inflorescence is a very fine branched panicle, 1-flower per spikelet. Agrostis capillaris, like many other members of the Agrostis genus are a valuable agronomic species because of their ability to produce fodder as well as provide food for grazing animals (APHIS, undated). 61 (1753). The long, naked, straight and wiry inflorescence branches diverging at right angles are distinguishing. SITE CHARACTERISTICS: Rough bentgrass occurs throughout a wide variety of habitats including woodlands, forest openings, grasslands, shrublands, meadows, swamps, bogs, marshes, and stream and lake … 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.

Agrostis gigantea is a perennial C 3 grass (Waller and Lewis 1979), to 1 m (usually much shorter), stems erect to reclining (USDA, NRCS 2006), sod-forming from rhizomes; new shoots arising at base of old flowering stems in late summer and fall.. Leaves alternate, blade 0.3-0.8 cm wide, much shorter than flowering stems, ligule 0.3-0.6 cm long, longer than wide. : Punctodera punctata E and A. sp. Ligule membranous. Agrostis dubia DC. Inflorescence to 12 cm long: 8: 8. Derivation: Greek agrostis, name of a grass. Spikelets. 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.
