Cover Crop Information Sheet BLACK OATS (Avena strigosa) True black oats (Avena strigosa) are a different species than oats (Avena sativa) usually planted in the Coastal Plain. They produce a dense, thick growth and will produce comparable biomass to cereal rye at half to 2/3 the height. They are less cold tolerant than common oats. There are two varieties of black oat available for sale in the U.S. – “SoilSaver” and “Pratex”. Seeds for SoilSaver are not currently commercially available due to seed crop failure. Recommended Varieties Variety Reasons Why Source SoilSaver Increased cold tolerance.

They will usually winter kill USDA Black Oats Plant Guide at less than 19F depending on growth stage. SoilSaver was developed to be more cold tolerant. Black oats can be terminated by herbicides, rolling & crimping, mowing, and tillage. They can be killed by rolling & crimping alone at the early milk stage. Rolling & crimping should be combined with herbicides at earlier growth stages. Consult your local Extension and state Pest Management Handbook for herbicide recommendations.

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.

Investigation of the Origin of the Avenacin Gene Cluster for Synthesis of Defense Compounds in Oats
Adaptive metabolic gene clusters as toolkits for chemical innovation: Investigation of the origin of the avenacin gene cluster for synthesis of defense compounds in oats Hoi Yee Chu (Athena) A thesis submitted to the University of East Anglia for the degree of Doctor of Philosophy University of East Anglia John Innes Centre Norwich, the United Kingdoms September 2013 c This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with the author and that use of any information derived there-from must be in accordance with current UK Copyright Law. In addition, any quotation or extract must include full attribution. Abstract Operon-like gene clusters are functional cassettes of physically linked and non-homologous genes involved in the same pathway. To date, 20 such plant gene clusters have been discovered, all of which are involved in specialised metabolism. Plant gene clusters raise interesting biological questions about their importance and the drivers behind their formation. This thesis describes the investigation of the evolution of the avenacin gene cluster, discovered in the diploid oat Avena strigosa S75, via wet-bench experiments and bioinformatic analyses, commencing with the general introduction (Chapter 1). Chapter 2 to 4 describe the survey on the avenacin production, expression pattern and phylogeny of the five characterized avenacin biosynthetic (Sad) genes within Aveninae, focusing on Avena L. The genomes of all Avena spp. investigated, including the avenacin deficient A. longiglumis, possess the five Sad gene homologues. The expression pattern of the Sad gene homolgoues vary in a genome-type dependent manner that it is root-specific amongst A genome oats.

They are the most widely grown plant generally considered healthy food being commercially nutritious as well. Oat grain, oat bran, and oatmeal contain a soluble dietary fiber known as β-glucan, which can reduce serum concentration of total cholesterol and low–density lipoprotein cholesterol and also effective in lowering blood sugar levels. Various experimental studies have shown that oat is potential agent to prevent the induction and progression of various diseases such as cancer, bowel, malfunction, obesity, celiac disease etc. This review will discuss functional and medicinal properties of Avena sativa. However, owing to the numerous health benefits that they offer, their consumption has increased to quite an extent and they have now come to the forefront. Keywords : Avena sativa , β-glucan, functional and medicinal properties ______________________________________________________________________________ INTRODUCTION Avena sativa is the scientific name of grass commonly known as oats and ‘‘Jai’’ or ‘‘Javi’in Hindi. It belongs to natural order graminaceae. The common oat ( Avena sativa ) is a species of cereal grain grown for its seed, which is known by the same name (usually in the plural, unlike other grains).

A Multilevel Exploration of Avena Strigosa Diversity As a Prelude To
Podyma et al. BMC Plant Biology (2019) 19:291 https://doi.org/10.1186/s12870-019-1819-6 RESEARCH ARTICLE Open Access A multilevel exploration of Avena strigosa diversity as a prelude to promote alternative crop Wiesław Podyma1,2 , Paulina Bolc1 , Joanna Nocen1 , Marta Puchta1 , Sylwia Wlodarczyk1 , Boguslaw Lapinski1 and Maja Boczkowska1,2* Abstract Background: Sand oat (Avena strigosa Schreb.), one of the four cultivated species of the genus Avena, could be considered as another alternative crop. In gene banks 865 germplasm samples of this species have been preserved that have not been thoroughly investigated so far. The results of phenotyping (36 traits), isoenzymatic (12 systems) and genetic (8 pairs of Sequence-related amplified polymorphism markers) variation were used to obtain the complete description of 56 accessions diversity originated from different parts of world. Results: Breeded and weedy forms represented similar pool of morphological traits that indicated a short-term and extensive breeding process, albeit all accessions which we classified as cultivated were characterized by better grain and green mass parameters compared to the weedy ones. Isoenzymes showed relationships with geographical origin, which was not possible to detect by SRAP markers. There was no similarity between morphological and biochemical results. The polymorphism level of SRAP markers was lower than indicated by the available literature data for other species, however it may result from the analysis of pooled samples of accessions with a high internal variability. The extensive type of breeding and its relatively short duration was also reflected in the population structure results. Joint analysis revealed that a secondary centre of diversity is being created in South America and that it has its genealogy from the Iberian Peninsula.

Jammu & Kashmir. India Accepted 12 April, 2013 Seven species of oat (Avena) were evaluated for their relative drought tolerance under soil moisture stress. The plant height, leaf area production and biomass yield reduced under soil moisture stress. Among the species tested, minimum reduction in height was recorded in Avena vaviloviana, Avena abyssinica and Avena sterilis at vegetative and flowering stages. Significant decrease in leaf area production was recorded at vegetative stage, whereas at flowering stage, the decrease in leaf area production was marginal in A. sterilis followed by A. abyssinica predicting their more adaption to stress environment. The increase in specific leaf weight (SLW) of all the species of Avena showed increase in leaf thickness, exhibiting high water retention capacity under soil moisture stress condition which is a requisite trait for drought tolerance. Soil moisture stress imposed at vegetative and flowering stages reduced fresh biomass yield in all the species. Minimum reduction in dry biomass accumulation under stress environment at vegetative stage was recorded in A. sterilis followed by A. strigosa and A. sativa, exhibiting their tolerance to drought at early stages of growth.

Zehzad Department of Biology, Faculty of Science, Shahid Beheshti University, Tehran, Islamic Republic of Iran Abstract Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. ludoviciana possessed 2n = 6x = 42 (hexaploid) chromosome number. Tetraploid and hexaploid species showed diplontic behavior and formed only bivalents. The species and populations studied differed significantly in the frequency of chiasmata. B-chromosomes occurred in some of the species studied. Cytomixis and chromosome elimination led to aneuploid and unreduced pollen mother cell formation in the species studied.

Identification of Wild-Oats Dr Stephen Moss ROTHAMSTED RESEARCH in the UK, There Are Two Main Species Which Occur As Weeds of Arable Crops
® Identification of wild-oats Dr Stephen Moss ROTHAMSTED RESEARCH In the UK, there are two main species which occur as weeds of arable crops. Their relative fequencies, as reported in the Atlas of the British Flora (2002), are given as the (%) of the 2852 10 x 10 km grid squares surveyed in which the species was detected. Avena fatua – common Avena sterilis ssp. ludoviciana or spring wild-oat – winter wild-oat Occurs throughout England; Less common and mainly found more scattered distribution in within 50 – 100 miles of Oxford Scotland and Wales.

(March/April) but with a Probably under-reported due variable, and sometimes to confusion with Avena fatua. considerable, amount of Germinates mainly in autumn autumn germination too (mainly Sept/Oct). and winter, from October to early March, and is more tolerant of freezing conditions than Avena fatua. Both species may occur within a single field, sometimes in mixture but sometimes in separate patches. Why does identification of species matter? Avena sterilis ssp. ludoviciana is generally considered the more challenging species to control, requiring more robust strategies Seedling emergence patterns and winter hardiness differ between the two species so correct identification can help in herbicide decision-making Although herbicide resistance has been found in both species, it is relatively more common in Avena sterilis ssp. ludoviciana. The first cases of resistance in the UK were all found in this species despite its more limited distribution. At the vegetative stage, wild-oats can be identified in cereal crops by: Hairy leaf margins and the absence of auricles Auricles No auricles on wild-oats Wheat - well developed, Barley - large, (or cultivated oats) but hairy auricles (hairs hairless auricles.
