“…The lower sucrose concentration under K deficiency was accompanied by accumulation of simple sugars glucose, fructose, and ribose, and sugar alcohols, which agreed with the observations made under P deficiency [27]. Simple sugars play important role in seed germination and desiccation tolerance during seed maturation [44]. Accumulation of sugar alcohols such as mannitol, myo-inositol, and pinitol act as compatible solutes and help to maintain the cellular integrity of membranes, and are strongly correlated with plant tolerance to abiotic stresses [45].…”

Impacts of potassium (K) deficiency and elevated carbon dioxide (eCO 2) on seed constituents have rarely been explored in most crops including soybean. A controlled environment experiment was conducted with soybean grown under a sufficient (5.0 mM) and two deficient (0.50 and 0.02 mM) levels of K fertilization at ambient (aCO 2) and eCO 2 (400 and 800 µmol•mol −1 , respectively). Both treatments significantly affected several constituents, with the K deficiency having stronger impacts than eCO 2. Out of 49 seed constituents, K deficiency and eCO 2 influenced 41 and 16 constituents, respectively. The K deficiency primarily decreased on average 16 constituents including minerals (e.g., K, P, Mg, Mn, Zn, Fe, B), oil, and essential fatty acids (e.g., linoleic and linolenic acids) but enhanced 25 constituents such as protein, amino acids, simple sugars, and stress-responsive metabolites (e.g., sugar alcohols mannitol and myo-inositol and proline). An accumulation of N while decreased C concentration resulted in the lower C:N ratio in the seeds of K-deficient plants. However, protein:oil, C:K, N:P, and N:K ratios were consistently greater under K deficiency. The eCO 2 also decreased minerals such as P, S, Zn, B, and essential fatty acids but enhanced the concentration of six constituents including alanine, oleic acid, fructose, and sugar alcohols across K fertilization. In addition, the impact of eCO 2 on several amino acids appeared to be dependent on the severity of K deficiency. For instance, eCO 2 decreased essential amino acids (e.g., valine, phenylalanine, isoleucine) in the seeds of severely K-deficient plants but not in the other treatments leading to a K × CO 2 interaction. Results showed that CO 2 enrichment is likely to exacerbate the decline in the concentration of seed minerals such as P, K, S, Zn and B, essential fatty acids, and amino acids under K limited conditions.

“…Among the carbohydrates, stachyose and sucrose consumption was found to be signiÞcantly different at almost all feeding durations. Soluble carbohydrates may have important roles in seed germination, seed desiccation tolerance, and cold stress tolerance (Obendorf and Kosina 2011). Furthermore, the nutritional role of carbohydrate content in soybean seed cannot be undermined, as it affects soyfood quality and nutritional values; glucose, fructose, and sucrose are readily digestible (Messina 2003), while rafÞnose and stachyose are indigestible and cause undesirable ßatulence and diarrhea (Rackis 1975).…”

Changes in protein, lipid, and carbohydrate content, and the weight loss of soybean seeds caused by the feeding of 6- to 7-d-old unmated male adults of the pentatomids Peizodorous hybneri (Gmelin) and Halymorpha halys (Stål), and an alydid, Riptortus pedestris (F.), were examined in the laboratory. Our goals were to determine which species had the greatest capacity to damage soybean seed and to measure the effect of that damage on the nutritional composition of soybean seed. Individuals of the three species were provided with a preweighed dry soybean seed and allowed to feed for 0, 4, 8, 12, 16, 20, and 24 d, after which the remaining seed was analyzed for any change in weight, protein, lipid, and carbohydrate concentration. Lipids, carbohydrates, and seed weights were reduced by bug feeding, and the reduction was directly proportional to feeding duration. H. halys was found to be the most voracious feeder, reducing soybean seed weight by 42% after 24 d of feeding. There was a significant interaction between species and feeding duration for changes in nutritional components. Seeds fed on by H. halys had the highest incremental increase in protein content (13%) after 24 d of feeding, followed by those fed on by R. pedestris and P. hybneri. However, carbohydrates and lipid content of the soybean seeds fed by the tested insect species were found to decrease significantly. Soybean pods at mature stages remain in the field for a long period, and findings of our study suggest that longer exposure of the mature soybean pods to these pest species in the field may lead to low-quality seeds and lower yields, and may even affect the germination potential of the seeds.

“…In fact, lipid and sucrose are abundant in soybean seed (Young and Mebrahtu, 1998;Obendorf et al, 2011), and decrease during germination as well (Pazur et al, 1962;Brown et al, 1962;Joshi et al, 1973;Kuo et al, 1990). However, to our knowledge, the contribution of each above compound in respiratory metabolism during soybean seed germination has not been clarified yet.…”

Role of raffinose family oligosaccharides (RFOs), sucrose and lipid in respiration metabolism during soybean seed germination were investigated to determine appropriate method for producing soybean sprouts containing high amount of RFOs. Soybean seed were soaked into 50 mM 1-deoxygalactonojirimycin (DGJ), which is a specific a-galactose inhibitor, for 90 minutes before and after germination preparation phase (GPP). Soybean seed without DGJ treatment was used as control. The growth rate, respiration rate, respiratory quotient, fatty acids and saccharides contents were measured during cultivation at 20. When DGJ was applied before GPP, the degradation of RFOs was significantly reduced, moreover the growth rate and respiration rate were suppressed due to the alternation of respiratory substrate from glucose to lipid in GPP. However, in the DGJ application after GPP, no difference was found from control although RFOs breakdown was functionally inhibited in subsequent radicle elongation phase (REP). These results suggest that RFOs are essential only in GPP as a source of respiratory substrate and lipids play the main role in respiration during REP. Therefore, prevention of RFOs degradation after GPP could be useful to maintain high amount of RFOs in soybean sprouts.
