“…A positive influence on high root yield achievement marked the Khoy environment as favorable for sugar beet growing. A low night temperature, especially in summer, may contribute to lower respiration and higher sugar accumulation in the root (Fasahat et al, 2018). Considering that the grouping of experimental stations in terms of sugar yield is similar to that for root yield, it seems that the sugar yield is more affected by root yield than sugar content.…”

“…Sugar is a strong and very energetic dietary substance, so that only 25 grams of sugar is enough to produce 100 calories (https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/sugar/sugar-101). The sucrose content in sugar beet has increased from 6% (fresh weight) in the initial selection to 18% (fresh weight) in today's hybrids (Fasahat et al, 2018).…”

SummaryThe evaluation of sugar beet genotypes under different climate conditions is a principal goal of breeding programs. In most studies, environment has a high influence on the qualitative and quantitative traits of sugar beet. Therefore, data collected from different environments may contribute to more accurate genotype selection. In this study, the effect of different environments on sugar beet genotypes’ performance was evaluated using a meta-analysis method based on Hedges’ technique. Data were collected from 149 trials conducted in twelve regions in Iran over 15 years (2003–18). For all trials, the value of the traits was weighted, and subsequently the effect size, reaction ratio and confidence interval were estimated. Among the studied environments, Khoy had a positive effect on root yield, sugar content, sugar yield and white sugar yield. As could be expected, the effect of environment on final yield formation was high, so that the Shiraz environment had a negative effect on root yield and sugar yield. Overall, the ranking of environments based on the meta-analysis results was quite different from that obtained by comparison of mean results.

“…The integration of HMF production in biorefinery concepts requires a suitable starting biomass, which initially contains a high amount of glucose to be converted by hydrothermal treatment. One of the biomasses, which fits this purpose, is sugar beets originally containing 15–20 wt.% sugar [ 21 ]. The sugar is extracted during industrial processes, while the rest of the plant serves as a mediocre fertilizer or animal feed [ 21 ].…”

“…In 2018/2019, Südzucker, a leading sugar production company of Germany, produced 4.6 million tons of sugar from 29.4 million tons of sugar beets [ 22 ]. Totally, 25% of the sugar produced worldwide originates from sugar beets [ 21 ]. Thus, a high amount of potential feedstock for biorefineries is available, which would be another advantage adding to the short ways between farms and sugar production facilities [ 23 ].…”

Hydrothermal Conversion of Spent Sugar Beets into High-Value Platform Molecules

The growing importance of bio-based products, combined with the desire to decrease the production of wastes, boosts the necessity to use wastes as raw materials for bio-based products. A waste material with a large potential is spent sugar beets, which are mainly used as animal feeds or fertilizers. After hydrothermal treatment, the produced chars exhibited an H/C ratio of 1.2 and a higher heating value of 22.7 MJ/kg, which were similar to that of subbituminous coal and higher than that of lignite. Moreover, the treatment of 25 g/L of glucose and 22 g/L of fructose by heating up to 160 °C led to a possible application of spent sugar beets for the production of 5-hydroxymethylfurfural. In the present study, the maximum concentration of 5-hydroxymethylfurfural was 3.4 g/L after heating up to 200 °C.

Early‐stage sugar beet taproot development is characterized by three distinct physiological phases

Despite the agronomic importance of sugar beet ( Beta vulgaris L.), the early‐stage development of its taproot has only been poorly investigated. Thus, the mechanisms that determine growth and sugar accumulation in sugar beet are largely unknown. In the presented study, a physiological characterization of early‐stage sugar beet taproot development was conducted. Activities were analyzed for fourteen key enzymes of carbohydrate metabolism in developing taproots over the first 80 days after sowing. In addition, we performed in situ localizations of selected carbohydrate‐metabolic enzyme activities, anatomical investigations, and quantifications of soluble carbohydrates, hexose phosphates, and phytohormones. Based on the accumulation dynamics of biomass and sucrose, as well as on anatomical parameters, the early phase of taproot development could be subdivided into three stages—prestorage, transition, secondary growth and sucrose accumulation stage—each of which was characterized by distinct metabolic and phytohormonal signatures. The enzyme activity signatures corresponding to these stages were also shown to be robustly reproducible in experiments conducted in two additional locations. The results from this physiological phenotyping approach contribute to the identification of the key regulators of sugar beet taproot development and open up new perspectives for sugar beet crop improvement concerning both physiological marker‐based breeding and biotechnological approaches.
