A cultivated oat linkage map was developed using a recombinant inbred population of 136 F6:7 lines from the cross 'Ogle' x 'TAM O-301'. A total of 441 marker loci, including 355 restriction fragment length polymorphism (RFLP) markers, 40 amplified fragment length polymorphisms (AFLPs), 22 random amplified polymorphic DNAs (RAPDs), 7 sequence-tagged sites (STSs), 1 simple sequence repeat (SSR), ...

La implementación de rotación cultivos puede modificar las características físicas y químicas los suelos ha sido recomendada para mejorar la calidad este. En Colombia, algunos productores implementan diferentes sistemas en papa, siendo importante conocer el potencial que pueden aportar a estos productivos. El objetivo este trabajo fue evaluar del suelo después utilizar esquemas cultivos. Se eva...

The first leaves (40 millimeters long) of 4-day-old light-grown Avena sativa L. cv Victory I seedlings contained a complete age sequence of cells from the base to the tip, and within these tissues all stages of chloroplast development could be observed. Although chloroplasts underwent progressive development, a marked increase in number of thylakoids per granum, in chloroplast volume, and in ch...

ABSTRACT Crown rust (Puccinia coronata) in indigenous populations of Avena sterilis has been cited as an example of stability of wild pathosystems that consist of natural mixtures of resistance and virulence. This study confirmed that virulence/avirulence polymorphisms in P. coronata on A. sterilis in Israel are highly diverse and that super races do not dominate. Isolates of P. coronata from I...

In this study we investigated the effect of maturity stage on chemical composition, in vitro dry matter digestibility (IVD) and volume of gas produced at 24 h (G24) of forages from Avena sativa L. (oats), Trifolium alexandrinum (berseem), Vicia sativa L. (vetch), Avena sativa-Vicia sativa (OV) and Avena sativaTrifolium alexandrinum (OB) mixtures collected at progressive morphological stages (S1...

The pH-dependence of acid-induced growth in excised segments of Avena sativa coleoptiles has been reinvestigated in the pH range 3 to 7. In contrast to previous reports (e.g. DL Rayle [1973] Planta 114: 63-73), only acidic buffers with a pH below 5.0 induce an extension response. A pH of 3.5 to 4.0 is required to mimic auxin-mediated growth. Very similar pH-response curves are obtained with bot...

Background: Avena sativa, a well-known herbal medicine; has been used in various skin diseases such as eczema, burn and pruritus. Objective: The objective of this study was to evaluate the effect of this herbal medicine for treatment of chronic pruritus in Sulfur Mustard (SM) exposed patients. Methods: Veterans who referred to Baghiat-Allah dermatologic clinic for itching problems were examin...

The elongation of etiolated Avena mesocotyls is inhibited by red light (660 mmu). Immediately after exposing mesocotyl sections to varying doses of red light the ensuing concentrations of phytochrome in the far-red absorbing form (P(730)) were measured. The extent of mesocotyl inhibition observed 5 days later is proportional to the logarithm of P(730) concentration in mesocotyl tissue at the ti...
