Identification of Cereal Remains from Archaeological Sites 2Nd Edition 2006
Identification of cereal remains from archaeological sites 2nd edition 2006 Spikelet fork of the “new glume wheat” (Jones et al. 2000) Stefanie JACOMET and collaborators Archaeobotany Lab IPAS, Basel University English translation partly by James Greig CEREALS: CEREALIA Fam. Poaceae /Gramineae (Grasses) Systematics and Taxonomy All cereal species belong botanically (taxonomically) to the large family of the Gramineae (Poaceae). This is one of the largest Angiosperm families with >10 000 different species. In the following the systematics for some of the most imporant taxa is shown: class: Monocotyledoneae order: Poales familiy: Poaceae (= Gramineae) (Süssgräser) subfamily: Pooideae Tribus: Triticeae Subtribus: Triticinae genera: Triticum (Weizen, wheat); Aegilops ; Hordeum (Gerste; barley); Elymus; Hordelymus; Agropyron; Secale (Roggen, rye) Note : Avena and the millets belong to other Tribus. The identification of prehistoric cereal remains assumes understanding of different subject areas in botany. These are mainly morphology and anatomy, but also phylogeny and evolution (and today, also genetics). Since most of the cereal species are treated as domesticated plants, many different forms such as subspecies, varieties, and forms appear inside the genus and species (see table below). In domesticates the taxonomical category of variety is also called “sort” (lat. cultivar, abbreviated: cv.). This refers to a variety which evolved through breeding. Cultivar is the lowest taxonomic rank in the domesticated plants. Occasionally, cultivars are also called races: e.g. landraces evolved through genetic isolation, under local environmental conditions whereas „high-breed-races“ were breed by strong selection of humans. Anyhow: The morphological delimitation of cultivars is difficult, sometimes even impossible. It needs great experience and very detailed morphological knowledge. -

EXECUTIVE SUMMARY ࢝ The Canadian Food Inspection Agency (CFIA) was notified on January 31, 2018, about a few wheat plants found on an access road in southern Alberta that survived a spraying treatment for weeds. ࢝ The CFIA’s tests confirmed that the wheat found is genetically modified to be herbicide tolerant. Genetically modified (GM) wheat is not authorized to be grown commercially in any country. ࢝ Since being notified, the CFIA worked diligently with federal and provincial partners and other stakeholders to determine the origin and extent of the GM wheat plants to get as much complete, accurate, and credible information about this discovery as possible. Based on extensive scientific testing, there is no evidence that this GM wheat is present anywhere other than the isolated site where it was discovered. ࢝ There is also no evidence that this wheat has entered the food or animal feed system, nor is it present anywhere else in the environment. ࢝ Health Canada and the CFIA have performed risk assessments of this finding, and have concluded that it does not pose a food safety, animal feed, or environmental risk. ࢝ The wheat plants found in Alberta are not a match for any wheat authorized for sale or for commercial production in Canada. -
Khorasan (Kamut® Brand) Wheat
Khorasan (Kamut® Brand) Wheat Introduction Khorasan wheat (Triticum turgidum, ssp. turanicum) is an ancient wheat variety that originated in the Fertile Crescent in Western Asia. It is a relative of durum wheat and is believed to have come to North America from Egypt, following World War II. It was rediscovered in 1977 by a Montana farmer who spent the next few years propagating the small supply of original seed. In 1990, khorasan wheat was first sold under the trademark KAMUT® in the United States. The trademark was implemented to preserve minimum standards for the khorasan wheat variety and to ensure consistent quality and market supply. KAMUT® wheat is currently only grown as KAMUT® wheat has larger heads, awns and kernels than an organic certified grain and hard red spring wheat and durum. marketed to various countries Photo courtesy T. Blyth, Kamut International around the world. Plant Adaptation KAMUT® wheat production is well suited to growing conditions found in southern Alberta and southern Saskatchewan, similar to durum. Northern regions with cooler, wetter conditions are less favorable for KAMUT® wheat production as disease risk may be greater and the crop requires about 100 days to mature after seeding or approximately one week later than spring wheat. KAMUT® wheat will grow well in any soil that is suitable for other cereal grain production. KAMUT® wheat has a growth pattern similar to spring wheat varieties. Each sprouted kernel produces one or two stems per seed, and each stem produces a large head with long black awns. It has moderate straw strength and grows to approximately 127 cm (4.2 ft) tall. -
Spelt Wheat: an Alternative for Sustainable Plant Production at Low N-Levels

To promote sustainability and biodiversity conservation, there is a growing interest in some old wheat species that can achieve better grain yields than the new varieties in marginal soil and/or management conditions. Generally, common wheat is intensively studied but there is still a lack of knowledge of the competitiveness of alternative species such as spelt wheat. The aim is to provide detailed analysis of vegetative, generative and spectral properties of spelt and common wheat grown under different nitrogen fertiliser levels. Our results complement the previous findings and highlight the fact that despite the lodging risk increasing together with the N fertiliser level, spelt wheat is a real alternative to common wheat for low N input production both for low quality and fertile soils. Vitality indices such as flag leaf chlorophyll content and normalized difference vegetation index were found to be good precursors of the final yield and the proposed estimation equations may improve the yield forecasting applications. -

Black Chaff of Wheat Stephen N
® ® University of Nebraska–Lincoln Extension, Institute of Agriculture and Natural Resources Know how. Know now. G1672 (Revised December 2012) Black Chaff of Wheat Stephen N. Wegulo, Extension Plant Pathologist widely distributed bacterial disease of small grains and can Cause, symptoms, disease cycle, and management cause yield losses of up to 40 percent. of black chaff of wheat. Cause and Symptoms Black chaff is a bacterial disease of wheat common in Black chaff is caused by the bacterium Xanthomonas irrigated fields or in areas with abundant rainfall during the campestris pathovar (pv.) undulosa. The disease derives its growing season. It is also known as bacterial stripe or bacte- name from the darkened glumes of infected plants (Figure rial leaf streak. The disease also occurs on barley, oats, rye, 1A). This symptom is similar to that caused by genetic triticale, and many grasses. It is the most important and most melanism (darkening of tissue) and glume blotch incited by Stagonospora nodorum. Black chaff can be distinguished from other diseases by the appearance of cream to yellow bacterial ooze in the form of slime or viscous droplets produced on infected plant parts during wet or humid weather. This ooze appears light colored and scale-like when dry. Bands of necrotic and healthy tissue on awns (“barber’s pole” appearance) are indicative of black chaff. A dark brown to purple discoloration may appear on the stem below the head and above the flag leaf (Figure 1B). On leaves, symptoms start as small water-soaked spots or streaks that turn brown after a few days. -

Wheat Cleaning Basics
Goal in Wheat Cleaning • Remove Non-Wheat Material – Metal – Foreign Material (Debris) – Stones – Grains other than wheat (soybean, corn, sorghum,… etc. – Weed Seeds • Remove Wheat not-fit for Milling – Shrunken & Broken – Diseased & Damaged Non-Wheat Material Wheat not-fit for Milling Shrunken/Shriveled Diseased- Scab Insect Damaged Black Tip (color defect) Ergot Heat Damaged Physical Properties of Common Impurities • Impurities are separated from wheat based physical differences which aid their removal. • Magnetic properties • Flow in air properties • Size and shape • Density • Friability (easily broken by impact) • Surface characteristics (color and texture) Wheat Cleaning System Cleaning System Design Principle 1. Eliminate impurities that pose a significant health and safety risk first. – Ferrous Metal (grain dust explosion hazard). – Grain Dust (explosion risk, health/safety risk). 2. Eliminate impurities which impact downstream machine efficiency. – Light chaff and dust (bulky, poor flow characteristics, decreases screening efficiency). Generic Cleaning Flow Principle Magnetic Separation Dust/chaff removal Size- coarse tolerance Larger/Smaller Size- fine tolerance Density Length Width Shape Friction/Abrasion Impact Friability Color/ Surface Characteristics Pre-Cleaning for Wheat Storage Benefits of Pre-Cleaning • Decrease infestation risk. • Improve sanitation and dust control. • Decrease microbial growth. • Improves flow of grain through the bin. • Increases storage life of grain. Generic Cleaning Flow Principle Grain Dust Explosion Risk. Magnetic Separation Explosion risk, sanitation, health and safety risk. Dust/chaff Removal Greatly improves equipment efficiency. Least similar to wheat based on size. Easy to remove. Larger/Smaller than wheat Reduces bulk. Lighter than wheat. Stones and mud removal. Density High and low density separation. Magnetic Separator • Tramp Iron or Tramp metal is metal brought in with grain at recieveing. -

Qualities of Einkorn, Emmer, and Spelt
Qualities of Einkorn, Emmer, and Spelt Frank J. Kutka Farm Breeding Club Co-Coordinator Northern Plains Sustainable Agriculture Society Einkorn | Favored for adding excellent flavor to foods. | Suitable for baked products, some good for bread. | Higher lipid content than bread wheat (4.2 vs. 2.8 g/100g. | Usually high in minerals although low in Cadmium. | Usually higher in protein, lutein, and Vitamin E; Lower in total phenols. | Has same allergenic proteins as other wheats but may be lower in some of the gliadins that cause responses in those with celiac disease: more research is needed. Emmer | Favored for adding excellent flavor to foods. | Recommended for children and new mothers in Ethiopia and for diabetics in India. | Gluten varies from very low to higher than bread wheat: bread making properties vary but are usually lower than bread wheat. Missing some gliadin proteins. | Usually has higher minerals, higher fiber and lower glycemic index. | Often has higher antioxidants (total phenolics and flavonoids) and protein. Not high in carotenoids. | Often has higher phytic acid concentration. Emmer | The species is a known source of disease and pest resistance traits (common bunt, stem rust, leaf rust, powdery mildew, Septoria Leaf Blotch, Loose smut, Tan Spot, Russian wheat aphid, Hessian Fly) | Asian and African types appear to be more drought tolerant | Some varieties have shown tolerance to higher soil salinity | Alternate source of dwarfing trait Spelt | Spelt has gluten and similar protein composition to bread wheat but reduced bread making quality. | Higher lipid and unsaturated fatty acid content. | Some minerals tend to be higher in spelt: Fe, Zn, Mg, P.
