Cover crops can improve soil health by maintaining organic carbon (SOC) and nitrogen (N) contents, yet their dynamics in relation to crop yield a semi-arid cropping system are poorly understood. The main objective of this study was evaluate the response diverse winter cover species mixture on SOC N fractions relationship with sorghum (Sorghum bicolor L. Moench) wheat (Triticum aestivum L.)–sorg...

two separate greenhouse experiments were conducted in the greenhouse of the iranian plant protection research institute, tehran, to compare the efficacy of some acetyl coa carboxylase (accase) and acetolactase synthase (als) inhibiting herbicides in control of wild oat biotypes. in each experiment, populations were independently treated by 10 herbicides each in 12 replications. to evaluate the ...

to study the effects of carbon dioxide enrichment on morphological, nutrient absorption and yield of wheat (triticum aestivum l. cv. pishtaz) under weed competitive pressure of wild oat (avena ludovicianal.), an experiment was conducted as a split plot based on a randomized completely block design during the 2013-2014 growing season at the research field of tarbiat modares university, iran. car...

To determine the functional homology between phytochromes from evolutionarily divergent species, we used the cauliflower mosaic virus 35S promoter to express a monocot (oat) phytochrome cDNA in a dicot plant (tomato). Immunoblot analysis shows that more than 50% of the transgenic tomato plants synthesize the full-length oat phytochrome polypeptide. Moreover, leaves of light-grown transgenic pla...

G. Klee, N. Mendoza, and J. Chavarría. 2011. Production and meat fatty acids profile of Hereford steers fed on pasture with and without oat grain supplement. Cien. Inv. Agr. 38(3): 331338. Live weight gain (LWG) and meat fatty acid composition (FA) were evaluated in Hereford steers fed on pasture with or without oat grain. The study site was non-traditional pastures were used in the dryland And...

Seeds have well-established passive physical and chemical defense mechanisms that protect their food reserves from decay-inducing organisms and herbivores. However, there are few studies evaluating potential biochemical defenses of dormant seeds against pathogens. Caryopsis decay by the pathogenic Fusarium avenaceum strain F.a.1 was relatively rapid in wild oat (Avena fatua L.) isoline "M73," w...

in order to evaluate competition among some weed species and canola, a field experiment in astan ghods razavi's field in mashhad was done on 2007-2008. thirty 50×50 cm quadrates were used in two times (stem and flower production) to measure the canola dry weight, leaf area index and canola and weeds density with destruction and thirty similar quadrates were used for counting weed species a...

Avena fatua (wild oat) populations with resistance (R) to one or more herbicides have been described in numerous cropping systems worldwide. We previously reported that the R3 and R4 wild oat populations from Montana, USA, were resistant to four herbicides representing three different modes of action: tralkoxydim [acetyl-CoA carboxylase (ACCase] inhibitor), imazamethabenz and flucarbazone [acet...

and range from 0.50 to 0.93 (Baker and McKenzie, 1972; Branson and Frey, 1989b; Brown et al., 1974; Schipper Increases in the groat (caryopsis)-oil content of oat (Avena sativa and Frey, 1991b). Genotype 3 environment interaction L.) raise the energy value of oat grain. Nine cycles of recurrent phenotypic selection for high groat-oil content were conducted in a genetifor groat-oil content is no...
