on of the most important of sugar beets quality is amount of sodium and potassium, because this compounds are strongly molassogenic and reduction of yield. so , attention on reasons that change this compound in sugar beets and consequently in produced juice are very important. in this study, effect of size of sugar beet (obtained from different areas) on changes of sodium and potassium are inve...

Sugar Beet Nematode (SBN), Heterodera schachtii, is one of the most destructive pests of sugar beets worldwide. It is present in all sugar beet growing areas of Wyoming and is particularly severe in fields located in close proximity to processing plants where sugar beets have been grown the longest. This soilborne, parasitic nematode attacks and destroys the small feeder roots of sugar beet pla...

cover type of on–farm storages has an important role in reducing the freezing damage and respiration of beet roots in the pile. this experiment was conducted in 2006 in karaj region in order to evaluate the effects of cover types of storage on the mass and sugar losses of both topped and untopped beets. the experimental design was a split plot factorial in rcbd with three replications. the main...

The amount of wheat and corn produced in excess will be sold at prices of $ 170 per ton for wheat and $ 150 per ton for corn. For sugar beets there is a quota on production which is 6000 T for the farmer. Any amount of sugar beets up to the quota can be sold at $ 36 per ton, the amount in excess of the quota is limited to $ 10 per ton. We denote by w1 and w2 the amount in tons of wheat resp. co...

It is not quite clear at present whether or not polyploidy could be used to increase the productivity of sugar beets (1, 3, 5) . However, triploids which show heterosis have been developed (2, 3) . Polyploidy increases the size of fruits and germs. This property, which counts for little in multigerm beets, can prove very useful in monogerm beets (4) . To gain the advantages of polyploidy, it is...

Sugar beet (Beta vulgaris L. cv. Monogerm C.S.F. 1971) seeds sown into Vineland fine sandy loam, infested with 15,500 H. schachtii juveniles/pot, showed little growth during an 11-week test in the greenhouse. Seedlings transplanted at 2, 4, and 6 weeks of age had 32, 30, and 31% less top weight and 71, 68, and 59% less root weight, respectively, compared to controls grown in nematode-free soil....

Gene flow is a crucial parameter that can affect the organization of genetic diversity in plant species. It has important implications in terms of conservation of genetic resources and of gene exchanges between crop to wild relatives and within crop species complex. In the Beta vulgaris complex, hybridization between crop and wild beets in seed production areas is well documented and the role o...
