Thinopyrum Ponticum Grass
ALL HEATGRASS G16 © photos G. Sainty & M. McCaskill T W SALTdeck Series Thinopyrum ponticum GRASS 8cm 1m lemma T. junceiforme Sea Wheat Grass spikelet not fully opened Sustainable TALL WHEATGRASS Grazing on SALTdeck Series Thinopyrum ponticum Saline Land © LWW & AWI 2006 Alternative names: Thinopyrum elongatum, Agropyron elongatum, Lophopyron elongatum. G16 Family: Poaceae. Description: Deep rooted tussock-forming perennial to 1.3 m tall. Leaves to 50 cm long, 4–8 mm wide, hairless or with scattered hairs, with a scabrous point and margins. Key features: Seedhead an unbranched spike to 30 cm long that breaks up at maturity, the spikelets placed with the flat side to the axis. Value: The most common cultivar is Tyrrell; DPI Victoria in 2001 released a more leafy cultivar named Dundas. Slow to establish and should not be grazed in its first year. Responds to hard grazing and the application of nitrogen. Subsoil moisture or summer rainfall is necessary for good production. Highly productive and of high nutritive value (supports high animal growth rates) if kept vegetative and leafy, but will revert to low nutritive value and palatability (less than a maintenance feed) if allowed to grow rank and set seed. Can be highly invasive in wetland areas. Salinity and waterlogging tolerance: Does not persist in soils that are waterlogged over spring and into summer. Grows in soils that have low to moderate salinity. Notes: Native of southern and eastern Europe, western Asia. Used in rehabilitation projects where there are soils with H moderate salinity (up to EC 30 dS/m). M References: Saltland Pastures in Australia, Barrett-Lennard, 2003. -

E-mail: [email protected] Received 7 November 2012; Revised 25 February 2013; Accepted 28 February 2013 Abstract The disease take-all, caused by the fungus Gaeumannomyces graminis, is one of the most destructive root diseases of wheat worldwide. Breeding resistant cultivars is an effective way to protect wheat from take-all. However, little progress has been made in improving the disease resistance level in commercial wheat cultivars. MYB transcrip- tion factors play important roles in plant responses to environmental stresses. In this study, an R2R3-MYB gene in Thinopyrum intermedium, TiMYB2R-1, was cloned and characterized. The gene sequence includes two exons and an intron. -
Plant Guide for Intermediate Wheatgrass (Thinopyrum Vigorous Seedlings, Rapidly Developing Rhizomes, Intermedium)
Plant Guide INTERMEDIATE It produces good hay yields, both in monoculture and in mixtures with alfalfa (Medicago spp.), where its WHEATGRASS stiff stems tend to keep alfalfa from lodging. Thinopyrum intermedium Intermediate wheatgrass has fairly slow re-growth (Host) Barkworth & D.R. following clipping and is best adapted to single crop- haying conditions (where rainfall patterns or limited Dewey irrigation prevents multiple cuttings in a season). Plant Symbol = THIN6 Intermediate wheatgrass responds very well to irrigation with initial production nearing the level of Contributed by: USDA NRCS Idaho Plant Materials orchardgrass (Dactylis glomerata) and meadow Program brome (Bromus biebersteinii) and exceeding smooth brome (Bromus inermis) under full irrigation. Meadow brome and orchardgrass have much better regrowth characteristics and will normally produce more than intermediate wheatgrass for hay production in multiple cutting situations. Intermediate wheatgrass responds very well to limited irrigation. It is able to tolerate droughty conditions when irrigation ceases as long as about 12-14 inches or more total annual moisture is provided. It provides excellent spring, early summer, and fall pasture, but must be carefully managed to ensure maintenance of the stand and high production. Intermediate wheatgrass is palatable to all classes of livestock and wildlife. It is a preferred feed for cattle, sheep, horses, deer, antelope, and elk in spring, early summer and fall. It is considered a desirable feed for cattle, sheep, horses, and elk in summer and winter. Erosion control/reclamation: Intermediate wheatgrass is well adapted to the stabilization of disturbed soils. This grass can be used in critical and urban areas where irrigation water is limited and to stabilize ditch banks, dikes, and roadsides. -
Grasses of the Texas Hill Country: Vegetative Key and Descriptions
Hagenbuch, K.W. and D.E. Lemke. 2015. Grasses of the Texas Hill Country: Vegetative key and descriptions. Phytoneuron 2015-4: 1–93. Published 7 January 2015. ISSN 2153 733X GRASSES OF THE TEXAS HILL COUNTRY: VEGETATIVE KEY AND DESCRIPTIONS KARL W. HAGENBUCH Department of Biological Sciences San Antonio College 1300 San Pedro Avenue San Antonio, Texas 78212-4299 [email protected] DAVID E. LEMKE Department of Biology Texas State University 601 University Drive San Marcos, Texas 78666-4684 [email protected] ABSTRACT A key and a set of descriptions, based solely on vegetative characteristics, is provided for the identification of 66 genera and 160 grass species, both native and naturalized, of the Texas Hill Country. The principal characters used (features of longevity, growth form, roots, rhizomes and stolons, culms, leaf sheaths, collars, auricles, ligules, leaf blades, vernation, vestiture, and habitat) are discussed and illustrated. This treatment should prove useful at times when reproductive material is not available. Because of its size and variation in environmental conditions, Texas provides habitat for well over 700 species of grasses (Shaw 2012). For identification purposes, the works of Correll and Johnston (1970); Gould (1975) and, more recently, Shaw (2012) treat Texas grasses in their entirety. In addition to these comprehensive works, regional taxonomic treatments have been done for the grasses of the Cross Timbers and Prairies (Hignight et al. 1988), the South Texas Brush Country (Lonard 1993; Everitt et al. 2011), the Gulf Prairies and Marshes (Hatch et al. 1999), and the Trans-Pecos (Powell 1994) natural regions. In these, as well as in numerous other manuals and keys, accurate identification of grass species depends on the availability of reproductive material. -

Scale Insects /Hemiptera, Coccoidea/ As a Source of Natural Dye and Other Useful Substances
VOL. 15 APHIDS AND OTHER HEMIPTEROUS INSECTS 151±167 Scale insects /Hemiptera, Coccoidea/ as a source of natural dye and other useful substances BOZÇ ENA èAGOWSKA,KATARZYNA GOLAN Department of Entomology, University of Life Sciences KroÂla LeszczynÂskiego 7, 20-069 Lublin, Poland [email protected] [email protected] Abstract For centuries some scale insect species have been used for the production of dye (Porphyrophora polonica, P. hameli, Kermes vermilio, Kerria lacca), wax (Ceroplastes ceriferus, C. irregularis, Ericerus pela), lac and shellac (K. lacca); these hemipterons are also the source of honeydew. Nowadays, some of them (Dactylopius coccus) deliver natural pigment which is used for yoghurt, sweets and soft drinks production. Polish cochineal is considered to be a historical and well-earned species for Poland. During Jagiellonian times it constituted one of the more important factors in national economy contributing to the country's prosperity and the society's well-being. Also today it could be used in many sectors of the eco- nomy, e.g. in food production. One of the factors which makes it more difficult to use species of the Porphyrophora genus in mass production of carmine dye is a too little content of dyeing substance in the bodies of these insects and a too large content of fat (about 30% of body mass) which inhibits the process of fabrics dyeing. An additional, though not less important problem is a remar- kable disappearance of P. polonica and P. hameli which is related with the damage of their natural habitats. The phenomenon of scale insect disappea- rance and the need for its protection was noticed back in the eighteenth cen- tury. -
