to study some physiological and morphological traits of sugar beet varieties in response to salinity stress, three multi-germ sugar beets (13030, 22393 and ic) were grown in the greenhouse, faculty of agriculture, shahid chamran university, in 2009. the experiment was carried out under three levels of salinity in from of sodium chloride source, that included control (zero), 100 and 200 mm uses ...

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...

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...

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 (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...

Invertase inhibitors have been isolated and partially purified from red beets, sugar beets, and sweet potatoes. These inhibitors are thermolabile proteins with molecular weights of 18,000 to 23,000. They do not inhibit yeast and Neurospora invertases, but they are reactive with potato tuber invertase and other plant invertases with pH optima near 4.5. There are differences in reactivity of the ...

Research and Marketing Act funds have been allotted to the Western Regional Research Laboratory for work on the technology of sugar beets. Liaison between the Laboratory and industry has been established through the Committee on processing problems, appointed by the industry. This committe has met at the Laboratory to discuss subjects meriting investigation and has proposed four problems: (1) s...
