The reaction of ingested forage plant fragments to the rumen environment may contribute to the rapid degradation of plant cell contents in the rumen. A series of experiments were used to explore the hypothesis that plant-mediated proteolysis (PMP) contributes to N loss from fresh forage entering the rumen, and to investigate the potential for identifying cultivars with reduced PMP. During an in...

Criconemoides xenoplax and Meloidogyne incognita were the nematode species most frequently associated with peach in North Carolina. Other nematodes often found in high numbers on that crop were Pratylenehus vulnus, Helicotylenchus spp., Trichodorus christiei, Xiphinema amerieanum and Tylenchorhynchus claytoni. P. vulnus and P. penetrans reproduced well on rootstocks of 21 peach cultivars tested...

This investigation studies CoFeB/AlOx/Co magnetic tunneling junction (MTJ) in the magnetic field of a low-frequency alternating current, for various thicknesses of the barrier layer AlOx. The low-frequency alternate-current magnetic susceptibility (χac) and phase angle (θ) of the CoFeB/AlOx/Co MTJ are determined using an cac analyzer. The driving frequency ranges from 10 to 25,000 Hz. These mul...

A total of 122 accessions of different wild and cultivated Pisum sp. were analysed using retrotransposon-based insertion polymorphisms (RBIP) markers. The Pisum materials included wild and cultivated (landraces and cultivars) materials from the World core collection of the John Innes Centre (JI) representing all generally recognized Pisum taxa, landraces materials from the Spanish core collecti...

puccinia recondite (leaf rust) is an endemic disease in iran; this disease can affect the productivity and quality of wheat, that occurring in all wheat growing regions. genetic resistance to leaf rust of wheat is the most important strategy to control the diseases and 51 leaf rust resistance genes (lr gene) are reported in wheat to provide resistance to leaf rust. this study aims to identify p...

The wheat proteins soluble in chloroform-methanol mixtures are associated with several kinds of food allergies. A separation method based on capillary zone electrophoresis (CZE) with UV detection was developed for the analysis of these mixtures. An acidic phosphoric acid/β-alanine (pH 2.5) buffer containing HPMC, urea and acetonitrile was used for the separation. The capillary electrophoresis (...

The peel volatile constituents and juice quality parameters of four tangerine cultivars were investigated in this study. Peel flavor constituents were extracted by using cold-press and eluted by using n-hexane. Then all analyzed by GC-FID and GC-MS. Total soluble solids, total acids, pH value, ascorbic acid as well as density and ash were determined in juice obtained from tangerine cultivars. F...

Snap bean (Phaseolus vulgaris L.) is a major crop in the Great Lakes region of the United States. The most significant production occurs in Wisconsin, Michigan, New York, Illinois, and Pennsylvania. Snap bean crops also are produced in the Pacific Northwest, Georgia, Florida, and Ontario, Canada. In 2005, 124,367 ha of snap bean were harvested with a farm gate value of approximately $400 millio...

The grain quality of chickpea in Iran is low and instable, which may be attributed to the evolution of cultivars with a narrow genetic base making them vulnerable to biotic stresses. Four chickpea varieties from diverse geographic origins were chosen and arranged in a randomized complete block design. Mesorhizobium sp. cicer strain SW7 was added to all the chickpea seeds. Chickpea seeds were pl...
