In their classic study of the enzymes involved in the mobilization of stored carbohydrate reserves in barley, Brown and Morris (3), in 1890, noted that the excised barley embryo formed a large quantity of starch when floated on water for a few hours. More recently investigators (2, 4, 5) working with excised barley embryos appear to have ignored or neglected this important biochemical transform...

Barley lectin is synthesized as a preproprotein with a glycosylated carboxyl-terminal propeptide (CTPP) that is removed before or concomitant with deposition of the mature protein in vacuoles. Expression of a cDNA clone encoding barley lectin in transformed tobacco plants results in the correct processing, maturation, and accumulation of active barley lectin in vacuoles [Wilkins, T.A., Bednarek...

The objective of this study was to explore the potential of near-infrared spectroscopy for determining the compositional quality properties of barley as a feedstock for fuel ethanol production and to compare the prediction accuracy between calibration models obtained using a Fourier transform near-infrared system (FT-NIR) and a dispersive near-infrared system. The total sample set contained 206...

BACKGROUND Archaeobotanical samples of barley (Hordeum vulgare L.) found at Qasr Ibrim display a two-row phenotype that is unique to the region of archaeological sites upriver of the first cataract of the Nile, characterised by the development of distinctive lateral bracts. The phenotype occurs throughout all strata at Qasr Ibrim, which range in age from 3000 to a few hundred years. METHODOLO...

The study was carried out to determine the gel pasting properties of barley (Hordeum vulgare L. cv. Geoncheonheugbori) as affected by different proton beam irradiation. The λmax, blue value, and amylose content were significantly associated with increasing proton beam irradiation. The pasting time in barley flour irradiated with proton beam ranged 0.09 to 0.16 min shorter than nonirradiated bar...

A study was conducted in an eight-arm radial maze to determine if cattle with various foraging experiences could facilitate location of feeding sites by other cattle. Heifers assigned as "followers" (n=24) were initially trained to expect straw at the end of each arm. Initial training of heifers assigned as "leaders" (n=12) differed based on the three following treatments:(1) no-experience, (2)...

The results of a comparative experiment the use an agricultural drone Agras T10 and ground machines (Amazone ZA-X Perfect fertilizer spreader, Amazone UF-901 sprayer) for application nitrogen fertilizers plant protection products (herbicides, insecticides fungicides treatment) are presented. Yield experimental control plots, economic efficiency unmanned technologies determined. Calculation tech...

Extreme weather phenomena linked to climate change are affecting the productivity of crops which main food sources nationwide, such as potatoes, wheat, barley, beans and corn. In addition, absence comprehensive agricultural extension technical assistance programs limits development sector. this context, research offers proposals for decision-making in two natural regions Peru (the coast highlan...

Soil compaction can affect crop growth and greenhouse gas emission and information is required of how both these aspects are affected by compaction intensity and weather. In this paper we describe treatments of compaction intensity and their effects on soil physical conditions and crop growth in loam to sandy loam cambisol soils. Soil conditions and crop performance were measured over three sea...
