Effect of Barley yellow dwarf virus Infection on Yield and Malting Quality of Barley

Barley yellow dwarf (BYD), the most common and widespread virus disease of cereal crops worldwide (14), may be caused by any one of several Barley yellow dwarf viruses (BYDVs) of the family Luteoviridae. Transmitted by at least 25 aphid species (24), these viruses historically have been classified into two subgroups and five strains based on aphid vector specificity and efficiency (31). However...

Microflora of barley kernels.

Numbers and kinds of microflora were determined in 160 samples of barley grown in different regions of the United States; microflora were more abundant in the grains grown in the central states than in those grown in the western states. During steeping and germination in micromalting equipment, the number of colonies of filamentous fungi increased from two to five times, colonies of yeasts from...

Influence of barley malting operating parameters on T-2 and HT-2 toxinogenesis of Fusarium langsethiae, a worrying contaminant of malting barley in Europe.

The fungus Fusarium langsethiae, exclusively described in Europe at present, seems to have taken the place of other Fusarium species in barley fields over the last 5 years. It has proved to be a highly toxic type-A trichothecene producer (T-2 and HT-2 toxins). The aim of this work was to study the ecotoxinogenesis of this fungus the better to identify and manage the health risk it may pose duri...

Simulation of yield and quality of malting barley

A computer simulation model was developed to determine the likely response of grain yield and quality of malting barley crops to differing availability of water or nitrogen (N) and differing soil and climatic conditions. The model was validated for New Zealand conditions by comparing the results of model simulations with data from malting barley crops grown in the Manawatu. Simulations were the...
