Home < Avena Sativa Research

The common oat plant (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).
While oats are suitable for human consumption as oatmeal and rolled oats, one of the most common uses is as livestock feed.
Oats make up a large part of the diet of horses and are regularly fed to cattle as well. Oats are also used in some brands of dog and chicken feed.

The effect of ground cover or initial organic carbon on soil fungi, aggregation, moisture and organic carbon in one season with oat (Avena sativa) plots
The unique capacity of fungi to efficiently sequester carbon in aerobic conditions, presents a way to maximize OC gain in agricultural systems. Oat (Avena sativa) was planted in the temperate climate of southern Ontario, Canada to study factors affecting soil organic carbon (OC). The plots varied with initial OC from 25 to 68 g kg−1 or with ground cover of differing decomposability (alfalfa (Medicago sativa) growing from seed, dried oat straw, dried hay and compost) on high OC soil (60–70 g kg−1). The soil was analysed for correlation of changes in soil aggregation, moisture, OC, fungal hyphal number and length and distribution of organic matter by mass and OC in density fractions within the growing season. At harvest, soil OC and moisture were increased only in plots with ground cover. Total hyphal length was not significantly different with ground cover treatment at harvest, and did not correlate with soil aggregation and soil OC. However, the number of hyphae with >5 μm diameter (primarily mycorrhizal fungi) correlated with % OC in ground cover plots while the number of hyphae <5 μm (primarily saprophytic fungi) correlated with % OC without ground cover in the gradient of initial soil OC. Mycorrhizal hyphae may be important to the increases in soil OC from surface treatment, although there was no treatment effect of mycorrhizal occurrence on the oat roots. This microcosm study, with growing and dried ground cover, suggests surface management may a simple and inexpensive means in agriculture to increase soil moisture and OC that benefits farmers as well as reducing atmospheric CO2.

Agronomic performance and quality of oat (Avena sativa L.) genotypes of worldwide origin produced under Central European growing conditions
One hundred and twenty oat (Avena sativa L.) genotypes of worldwide origin were evaluated for agronomic and grain quality characters in three replicated field experiments in Austria and one in Germany. Panicle emergence, plant height and lodging severity were evaluated under field conditions, and grain yield, thousand kernel weight, hectolitre weight, screenings percentage > 2 mm, and groat percentage were measured after harvesting. Substantial genetic variation and high heritability were observed for all traits. The highest yielding entries were improved cultivars from European breeding programs. Groat yield and grain yield were highly correlated. For agronomic traits such as earliness and plant height, and quality traits such as groat percentage, several of the overseas genotypes, mostly from the USA and Canada, showed better performance than the European cultivars. Selected lines from the North American breeding programs appear to be valuable resources for European avena sativa breeding programs, especially for the improvement of physical grain quality traits.

Occurrence and distribution of nitrogen fixing bacterial community associated with oat (Avena sativa) assessed by molecular and microbiological techniques
Molecular and microbiological techniques were used to evaluate the nitrogen fixing bacterial community associated with oat (Avena sativa) in different soil management systems of Rio Grande do Sul State. The conventional microbiological approach made use of semi-solid nitrogen-free and solid selective media to isolate some of these nitrogen fixing bacteria. For the molecular approach, a PCR-RFLP strategy was adopted to amplify a segment of the nifH gene, which encodes nitrogenase reductase, from DNA samples extracted from rhizosphere soils, roots and leaves of oat. The amplified nifH fragments were cleaved with TaqI and HaeIII endonucleases and the products analyzed in polyacrylamide gels. One sample was analyzed in more detail. From this site rhizosphere soil and leaf samples PCR fragments were cloned into pUC18, generating 55 nifH positive clones, from which 19 different RFLP patterns were obtained. These patterns were compared with RFLP patterns generated from DNA obtained from pure strains or by theoretical digestion data. To identify and confirm the RFLP patterns obtained, at least one clone of each was sequenced and the nucleotide sequences were compared with the GenBank nucleotide database. As the partial nifH sequences analyzed had shown homologies with several known and unknown diazotrophs, we attempted to identify the diazotrophs through the positioning of the clones in the NifH partial sequence-derived tree. Through the molecular biological analysis we were able to identify a reasonable occurrence of diazotrophs in the rhizosphere soil and leaf samples analyzed, 9 and 13 different genera, respectively. Of these, two genera were particularly abundant: Azospirillum and Herbaspirillum. These two genera were also the two most abundant genera isolated by conventional microbiological techniques. Both approaches indicated that the nitrogen-fixing communities were different in soils under cultivation and permanent pasture from these under cultivation without live stock. Our results showed that while the molecular approach gives us a general view of the variability of nitrogen fixers in the community, the conventional methodology allows us to isolate those bacteria and to select some of them that have showed the highest nitrogen fixation capacity and auxin production.

Characterisation of oat (Avena sativa L.) oil bodies and intrinsically associated E-vitamers
Transmission electron microscopy of sections of oat (Avena sativa L.) grain suggested that the highest concentrations oil bodies were in the aleurone and germ rather than the starchy endosperm. Oil bodies recovered from homogenized tissues by centrifugation and washed in (9 M) urea were significantly (P<0.05) enriched in lipid (93.3±1.4% dry wt) and low in protein (1.4±0.2%) compared with unwashed (40.2±1.9% lipid; 23.0±1.8% protein), water-washed (78.6±1.2% lipid; 7.8±0.5% protein), and salt-washed (1 M NaCl) oil bodies (89.9±0.4% lipid; 5.1±0.4% protein). Washing significantly reduced (P<0.05) the total phenolic content of the oil bodies but significantly increased concentrations of E-vitamers, on a dry weight basis, suggesting an intrinsic association between the E-vitamers and oat (avena sativa) oil bodies. The profile of E-vitamers in the oil bodies reflected that in oat grain with -tocotrienol accounting for ca. 66% of the total E-vitamers. These E-vitamers may provide oxidative stability to the membrane and/or oil of avena sativaoil bodies

The effect of breeding on allometry and phenotypic plasticity in four varieties of oat (Avena sativa L.)
New directions in crop improvement via alteration of plant responsiveness to variation in growth conditions are being actively debated. It appears, however, that little is known about the impact of previous breeding on the phenotypic plasticity of plants, which results from correlated responses to selection on high yield. We used four oat (Avena sativa) varieties, originating from 1930, 1952, 1980 and 1999, to examine the effects of long-term breeding on the patterns of autecological phenotypic responses to variation in light and nutrient supply. The modern variety showed the least plasticity in stem elongation in response to variation in light conditions. As a by-product of decreased sensitivity to light availability, the modern oat variety appeared to be more susceptible to low light levels compared to other varieties. The patterns of plastic response in leaf area and root biomass were similar in all varieties. Changes in allocation to panicles in response to resource variation were completely attributable to passive plasticity, i.e. the proportion of biomass invested into reproduction varied as a function of total plant size. Interestingly, variation in specific leaf mass, the trait considered to be important in adaptive shade-avoidance responses, was only partially attributable to ontogenetic plasticity (environmentally induced adjustments of ontogeny).
