Abstract A research experiment was conducted after sugar beet harvesting season of 2018/2019 to study the losses in sugar beet roots quality after harvesting and reducing it by using different storage methods (storage roots in shadow and open air), covering (without, covering with rice straw, sugar beet foliages and net) and spraying treatments (without, spraying with tap water and Mepiquat chloride at the rates of 0.5, 1.0 and 1.5 cm/L) during storage periods (one, two, three and four weeks from beginning the study) under environmental conditions of Dakahlia Governorate, Egypt. The experiment was carried out in factorial experiment in randomized complete blocks design with three replicates. Stored sugar beet roots in piles under shading net conditions indexed the highest sucrose and quality percentages and lowest K, Na and alfa amino nitrogen percentages in roots. The highest sucrose and quality percentages and lowest K, Na and alfa amino nitrogen percentages in roots were obtained by covering sugar beet piles with sugar beet foliages. The highest sucrose and quality percentages and lowest K, Na and alfa amino nitrogen percentages in roots were resulted when spraying piles before storage with Mepiquat chloride at 1.0 cm/L. It can be concluded that stored sugar beet roots after harvesting directly in piles under shading and covering with beet foliages and spraying piles with Mepiquat chloride at 1.0 cm/L to reduce losses in sugar beet roots quality after harvesting and during storage and achieve high quality characters of roots under the environmental conditions of Dakahlia Governorate, Egypt.

Close Relationship

The high yield level sugar beet has reached in the past years might have altered the morphology of the storage root. The study thus aimed at analyzing storage root diameter and length in relation to yield under various environmental conditions. For that purpose, data of various field and pot experiments were included covering a broad range of storage root diameters and yield levels of sugar beet. It turned out that there was a close relationship between storage root diameter and root yield, which was not affected by different environmental conditions (site, year). Furthermore, breeding progress had obviously not changed this relation, as it was not affected by varieties. Results from pot experiments could well be compared with field trial data. In field trials, storage root length did not exceed 25cm independent of yield level, whereas in pot experiments plants formed longer storage roots with higher yield levels. It is discussed that increasing penetration resistance in soil could limit the further expansion of the storage root diameter. A more aboveground growth of the storage root with increasing yield level, however, will make yield estimates based on root diameter more difficult.

Randomized Experimental Design

Improving environmental conditions in the production of seedlings by expanding the distribution of photosynthetically active radiation in abaxial leaves and protecting the substrate with straw can promote the production of higher quality seedlings. This study aimed to evaluate the reflective materials over the cultivation bench and the use of rice straw over the substrate in the formation of papaya seedlings of the group ‘Formosa’. The joint analysis was performed considering a completely randomized experimental design in a 3 x 2 factorial scheme, with five replications and six seedlings per plot. The use of aluminized screen (Aluminet®) and aluminum foil with an area of 1 m x 1.2 m as reflective material on the cultivation bench and treatment without reflective material were evaluated. Also, the presence and absence of a rice straw layer with 5 cm height, as covering over the substrate were evaluated. In the benches with aluminum foil and without reflective material, the seedling production without rice straw over the substrate provided papaya seedlings of higher quality than the rice straw over the substrate. The aluminum foil produced high-quality papaya seedlings in the treatments with rice straw over the substrate. The aluminized screen on the cultivation bench was not favorable for the papaya seedlings production.

Storage Methods

Different seed storage methods, varying in storage temperature, moisture and/or oxygen content, were applied to commercial sugar beet seed lots from four breeding companies. After storage for 10–11 months, germination of the seed was tested in the laboratory (cold test, 10°C). In addition, the contents of active ingredients (fungicides and insecticide) were analyzed and compared with the initial contents before storage. Based on these results, a selection of the most promising storage methods was made to test plant emergence in a field experiment. This research was performed in 2015/16 and in 2016/17. In both years, two storage treatments outperformed the others: these were storage in a closed jar with the addition of moisture absorber (i.e. silica gel) at room temperature and storage at –18°C in a closed plastic bag. Using these two storage methods, seed vigour and contents of active ingredients were comparable to those in seed that had not been stored for one year. Based on the results from this study, the advice to growers for a successful storage of residual sugar beet seed was adjusted in 2017, after including some practical guidelines and considerations.

AbstractThe gap between the current supply and future demand of meat has increased the need to produce plant-based meat analogs. Methylcellulose (MC) is used in most commercial products. Consumers and manufacturers require the development of other novel binding systems, as MC is not chemical-free. We aimed to develop a novel chemical-free binding system for meat analogs. First, we found that laccase (LC) synergistically crosslinks proteins and sugar beet pectin (SBP). To investigate the ability of these SBP-protein crosslinks, textured vegetable protein (TVP) was used. The presence of LC and SBP improved the moldability and binding ability of patties, regardless of the type, shape, and size of TVPs. The hardness of LC-treated patties with SBP reached 32.2 N, which was 1.7- and 7.9-fold higher than that of patties with MC and transglutaminase-treated patties. Additionally, the cooking loss and water/oil-holding capacity of LC-treated patties with SBP improved by up to 8.9–9.4% and 5.8–11.3%, compared with patties with MC. Moreover, after gastrointestinal digestion, free amino nitrogen released from LC-treated patties with SBP was 2.3-fold higher than that released from patties with MC. This is the first study to report protein-SBP crosslinks by LC as chemical-free novel binding systems for meat analogs.

Forage Intake

Compound feeds are frequently used at a fixed rate of 0.36kg to 0.40kg/kg milk produced, in addition to forage and other home-grown feeds. Such linear scales take no account of the curvilinear response of milk yield to concentrate feed intake, nor of the substitution effect of concentrate feed upon forage intake. In high-yielding herds, the use of fixed rate scales can result in the provision of concentrate feeds in excess of 10kg/d. An experiment was designed to evaluate whether milk yields could be maintained while reducing concentrate feed intake, and therefore placing greater reliance on forage intake, and including sugar-beet pulp as a source of highly digestible but non-starchy concentrate, and fish meal as a source of high quality undegraded dietary protein

Technological Quality

In 2005–2008, in several locations of southern Poland, the yield and technological root quality of two sugar beet cultivars (Esperanza and Henrike) cultivated in mustard mulch, straw mulch and in conventional tillage (with pre-winter plough) were investigated. Mustard mulch let to achieve the highest plant density during harvest. Replacing conventional ploughing with mustard mulch caused 9.4% root yield increase and with straw mulch 11.2%. Cultivation system had no effect on the content of sucrose and melassigenic components in the roots, except for potassium. Technological sugar yields obtained from mustard mulch were by 8.0% and in straw mulch by 11.3% higher than in the conventional tillage. Cv. Esperanza allowed getting the higher root yield, average fresh mass of single root and technological sugar yield, than cv. Henrike. In addition, lower content of alpha-amino-nitrogen was obtained from roots of the cv. Esperenza. In contrast, higher sucrose content and lower sodium content were found in the roots of cv. Henrike. The lowest variability in the sugar beet root yield features and technological quality was achieved from straw mulch.

Phoma Betae

Phoma betae from decayed sugar beet storage root tissue grew most rapidly in culture at 15C but produced more polygalacturonase (PG) at 20C. When the fungus was supplied with six different nitrogen sources, it produced the most PG on (NH4)2SO4.Assays of dialyzed culture filtrates using sodium polypectate and pectin or cell wall material from storage roots as the carbon sources showed the production of exopolygalacturonase (exo-PG) and endopolygalacturonate trans-eliminase (endo-PGTE). No pectin methyl esterase was detected. Exo-PG and endo-PGTE also were present in decayed sugar beet tissue. Only endo-PGTE was detected within 3 mm of tissue surrounding the rotted area.In culture, cell wall material from the susceptible variety A58 induced more endo-PGTE formation than the resistant 2B. But 2B induced more exo-PG formation than A58. It is suggested that endo-PGTE plays a major role in cell wall degradation because pH 7.5 was optimum for tissue maceration and pH 8.5 for enzyme activity and the advancing margins of rotted tissue contained only endo-PGTE.
