Background: Drought stress significantly limits oat (Avena sativa L.) growth and productivity. Thus an efficient management of soil moisture and study of metabolic changes in response to drought are important for improved production of oat. The objective was to gain a better understanding of drought tolerance mechanisms and improve soil water management strategies using water-saving superabsorbent polymer (SAP) at 60 kg ha-1 under three irrigation levels (adequate, moderate and deficit) using a new type of hydraulic pressure-controlled auto irrigator. Results: The results showed that the relative water content and leaf water potential (ψ1) were much higher in oats treated with SAP. Although the SAP had little effect on plant biomass accumulation under adequate and moderate irrigation, it significantly increased the biomass by 52.7% under deficit irrigation. Plants treated with SAP under deficit irrigation showed a significant decrease in superoxide dismutase, catalase, peroxidase, ascorbate peroxidase and glutathione reductase activities in leaves compared with control plants. Conclusion: Our results suggested that drought stress leads to production of oxygen radicals, which results in increased lipid peroxidation and oxidative stress in the plant, and the application of SAP could conserve soil water, making same available to plants for increased biomass accumulation and reduced oxidative stress especially under severe water stress.

Compounds released by mungbean roots potentially represent an enormous source of nitrogen (N) and carbon (C) in mungbean-oat intercropping systems. In this study, an in situ experiment was conducted using a 15N - 13C double stem-feeding method to measure N and C derived from the rhizodeposition (NdfR and CdfR) of mungbean and their transfer to oats in an intercropping system. Mungbean plants were sole cropped (S) or intercropped (I) with oat. The plants were labeled 5 weeks after planting and were harvested at the beginning of pod setting (Ip and Sp) and at maturity (Im and Sm). More than 60% and 50% of the applied 15N and 13C, respectively, were recovered in each treatment, with 15N and 13C being quite uniformly distributed in the different plant parts. NdfR represented 9.8% (Sp), 9.2% (Ip), 20.1% (Sm), and 21.2%(Im) of total mungbean plant N, whereas CdfR represented 13.3% (Sp), 42.0%(Ip), 15.4% (Sm), and 22.6% (Im) of total mungbean plant C. When considering the part of rhizodeposition transferred to associated oat, intercropping mungbean released more NdfR and CdfR than mungbean alone. About 53.4-83.2% of below-ground plant N (BGP-N) and 58.4-85.9%of BGP-C originated from NdfR and CdfR, respectively. The N in oats derived from mungbean increased from 7.6% at the pod setting stage to 9.7% at maturity, whereas the C in oats increased from 16.2% to 22.0%, respectively. Only a small percentage of rhizodeposition from mungbean was transferred to oats in the intercropping systems, with a large percentage remaining in the soil. This result indicates that mungbean rhizodeposition might contribute to higher N and C availability in the soil for subsequent crops. © 2015 Zang et al.

Background: The aim of present study is to investigate the influences of brewing and boiling on hypocholesterolemic effect of oatmeal in rats fed with a hypercholesterolemic diet. Methods: Fifty-six male Sprague-Dawley rats were divided into 5 groups of 8 rats each with similar mean body weights and serum cholesterol concentrations. Rats were fed with the experimental diets containing 10 % of oatmeal from two Chinese oat varieties which were brewed or boiled for 30 days. The lipids levels in serum, liver, and faeces were determined. Results: The effects of feeding boiled oatmeal on lowering lipid concentrations in plasma and liver were more significant than that of brewed oatmeal (P∈<∈0.05). Feeding boiled oatmeal was also more efficient in increasing fecal total lipids, cholesterol and bile acids as compared to feeding brewed oatmeal (P∈<∈0.05). Boiled oatmeal had higher apparent viscosity and soluble β-glucan content than the brewed oatmeal did (P∈<∈0.05). Conclusion: These results indicated that the capability of boiled oatmeal in improving cholesterol metabolism is better than that of brewed oatmeal, which is mainly attributed to its higher soluble β-glucan content and apparent viscosity. © 2015 Ban et al.

The effects of different inactivating treatments including hot air roasting, normal-pressure steaming, high-pressure steaming, infrared roasting, and microwave heating on the storage properties and flavor quality of oats were studied. These methods significantly inactivated the lipase of oats, even if using infrared roasting treatment had a worse inhibition effect of hydrolysis. As a result, the storage properties of oats were improved with different inactivating treatments, except infrared roasting. PCA analysis showed that all the oat flours could be clearly discriminated by the electronic nose. Sensory evaluation showed that the qualities of oat flour were hot air roasting (7. 25), infrared toasting (7. 17), microwave heating (5. 92), high-pressure steaming (5. 85), and normal-pressure steaming (5. 57). It was concluded that there was a significant relationship between inactivation treatment and oat flavor. That is to say dry heating resulted in more favorable sensory quality of oat flour. © 2011 Springer Science + Business Media, LLC.

Water use efficiency (WUE) and some crop physiological responses were studied when oat (Avena nuda L.) was applied with alternate partial root-zone irrigation (APRI). A field experiment was carried out with two organic fertilizer levels (e.g. 0 and 240 kg hm-2) and three irrigation levels (i.e. 60, 90 and 120 mm). The irrigation methods included the conventional irrigation (CI) and APRI. Compared with CI, APRI under the moderate water stress reduced water consumption by 9.97-12.46%, and improved WUE by 0-9.09%, but the grain yield was slightly reduced by 2.1-12.76%. APRI under the severe water stress would significantly (P<0.05) reduce the plant height than CI. APRI with organic fertilizer could increase the root shoot ratio by 18.18-45.45% after the grain filling stage. Under the severe water stress APRI significantly reduced the net photosynthetic rate (Pn), and these treatments with organic fertilizer generally had much higher Pn than those without organic fertilizer. Our results indicate that APRI under the moderate water stress improves WUE and root shoot ratio, and slightly reduce grain yield and Pn with applied organic fertilizer. © 2012 Published by Elsevier Ltd.

This paper monitored the oat growth and cation absorption characteristics on a saline-alkali soil in the Baicheng region of Jilin Province under low, medium, and high levels of salt stress. No significant differences were observed in the shoot growth and yield components under the three levels of salt stress, but the root biomass and root/shoot ratio decreased significantly with increasing salt stress level. At maturing stage, the root/shoot ratio under medium and high salt stresses was 77.2% and 64.5% of that under low salt stress, respectively. Under the three levels of salt stress, the K+/Na+ and Ca2+/Na2+ ratios in oat plant had significant differences at trefoil stage, but no significant differences at heading stage. With the increase of salt stress level, the cation absorption selectivity coefficient of oat at filling stage decreased significantly, but the transportation selectivity coefficient had no significant difference under the three levels of stress. It was concluded that oat could adapt to the salt and alkali stress of soda-alkaline soil to some extent, and the adaptation capability decreased with the increasing level of stress. The decrease of oat root biomass and the stronger ion selective absorption capacity at heading stage under salt and alkali stress could benefit the shoot growth and yield components of oat.

There is limited comparative research on the responses of crop growth and yield to N fertilization in hulless (Avena nuda) and hulled (Avena sativa) oats. A field study was conducted for 3 yr at Ottawa, ON, to assess the growth and grain yield of current wheat (Triticum aestivum), hulled and hulless oat cultivars with three N fertility levels. Averaged across the 3 yr, both the mid and high (75 and 150 kg N ha -1) N treatments demonstrated statistically similar, but higher, leaf area index (LAI) and total dry matter (TDM) than the 0 N treatment, regardless of crop types. At final harvest, with increasing N supply, both hulled oat Gosling and wheat cultivar AC Brio had similar and higher TDM than the hulless oat VAO-2 in 2006, whereas both oat cultivars produced much lower (>0.01) grain yield than wheat in 2008, primarily due to early lodging of the oat cultivars. Overall, the wheat cultivar AC Brio produced the greatest grain yield with the highest harvest index (HI), followed by hulled Gosling; the hulless oat had the lowest grain yield and the lowest HI. Compared with the wheat cultivar, the lower grain yield of both hulled and hulless oats was attributed to a lower (>0.05) HI and more severe crop lodging (especially when lodging occurred early), coupled with a higher LAI at flowering. Our results suggest that enhancing HI and resistance to crop lodging are the primary targets for both the hulled and hulless oat cultivar improvement in eastern Canada.

BACKGROUND: Normal pressure steaming (NPS), autoclaved steaming (AS), and hot-air roasting (HAR) are widely used to deactivate oat enzyme in the oat-processing industry. Infrared roasting (IR) is a new oat deactivation method, and is welcomed and employed by increasing numbers of oat-processing plants in China. It is widely known that oat starch plays an important role in the processing function of oat food, and that oat β-glucan and lipid contribute greatly to the health benefits of oat food. However, the effects of steaming and roasting treatments on the starch, β-glucan and lipid in oat kernels are poorly known. RESULTS:In this research, the level and distribution of β-glucan and lipid in oat kernels with and without deactivation treatments were tested. We also measured the viscosity properties of oat flour from kernels after NPS, AS, HAR and IR treatments, and examined the effects of these treatments on oat starch granularity using scanning electron microscopy. The results showed that the deactivation treatments did not have significant effects on oat β-glucan and lipid levels in oat kernels (P < 0.01). The distribution of β-glucan and lipid in enzyme-deactivated kernels was very similar to that in normal kernels. NPS, AS, HAR and IR treatments changed the shape of starch granules, crumbled large starch granules, reduced the connection between the protein network and starch granules, and improved starch gelatinization properties. CONCLUSIONS: NPS, AS, HAR and IR treatments can change the structure of oat starch granules and improve the viscosity property of oat starch without causing β-glucan and lipid loss to oat food. © 2010 Society of Chemical Industry.
