BACKGROUND During production of sugar beet (Beta vulgaris) seeds in greenhouses, workers frequently develop allergic symptoms. The aim of this study was to identify and characterize possible allergens in sugar beet pollen. METHODS Sera from individuals at a local sugar beet seed producing company, having positive SPT and specific IgE to sugar beet pollen extract, were used for immunoblotting....

background and objectives: the most important determining factor in sugar beet root yield is seed quality. seeds with germination percentage are lower; the germination is slow and non-uniform, will produce plants that initial growth is slow. according to various studies indicate that harvest time is an important factor influencing the quality of sugar beet seed. in the early harvest of sugar be...

monogerm and multigerm seed varieties are used in sugar beet cultivation. singling is inevitable and mechanization almost impossible when multigerm seed varieties are used. for this and for some other reasons, economically sound and fully mechanized cultivation of sugar beet calls for the use of monogerm seed varieties. throughout europe, only monogerm varieties are used in sugar beet productio...

Patterns of seed dispersal in the wild sea beet (Beta vulgaris ssp. maritima) are predicted to be influenced by marine currents because populations are widely distributed along the European Atlantic coast. We investigated the potential influence of marine currents on the pattern of spatial genetic structuring in natural populations of sea beet. Populations were located along the French coasts o...

in order to  study the effect of beet mosaic virus on sugarbeet seed yield, an isolate of beet mosaic virus was collected from sugarbeet fields in karaj and biologically was purified by inoculation on chenopodium amaranticolor and propagated on beta vulgaris cv. cicla under greenhouse conditions. the infected sap was inoculated on leaves of  sugar beet  7233 variety at  two stages, after and be...

Gene flow via seed or pollen is a basic biological process in plant evolution. The ecological and genetic consequences of gene flow depend on the amount and direction of gene flow as well as on the fitness of hybrids. The assessment of potential risks of transgenic plants should take into account the fact that conventional crops can often cross with wild plants. The precautionary approach in ri...

Sugar beet (Beta vulgaris) is a biennial plant that requires a cold period in order to induce flowering, a process called vernalization. The period of vernalization required to induce flowering can vary by genotype (between 90-120 days). Holding beets in cold storage (4C) at high humidity (95%) is expensive and labor intensive, requiring specialized equipment and multiple fungicide applications...

The mild climate of the Salinas Valley, CA lends itself well to a diverse agricultural industry. However, the diversity of weeds, crops and insect and fungal vectors also provide favorable conditions for plant virus disease development. This paper considers the incidence and management of several plant viruses that have caused serious epidemics and been significant in the agricultural developme...
