“…Germination inhibitor is a general term referring to toxic substances produced by the plant, as well as substances with related structures that are not found in the plants. These chemicals inhibit or delay the germination process of the seeds in either the same species or others [8,11,12]. This inhibitory action can be through an osmotic effect, liberation of toxic chemicals, or limitation of the oxygen supply [1,[11][12][13][14].…”

“…Phenols are chemically active and are easily oxidized [26]. The effect of these chemicals is in addition to osmotic properties, caused by salt crystals present in the pericarp [11,12,14,18,21]. Salt crystals in the pericarp can restrict the seed water and oxygen uptake [21].…”

“…Salt crystals in the pericarp can restrict the seed water and oxygen uptake [21]. However, the possibility of severe effects from the high osmotic value is low, due to the halophytic characteristic of sugar beet [12].…”

Endogenous inhibitors have a crucial effect on the success of sugar beet (Beta vulgaris) seed germination. The strength of this effect changes during seed maturation, and washing away these inhibitors can facilitate germination. Investigation of various washing factors such as water-to-seed ratio, stirring time, and speed of stirring on a mixed-maturity lot of sugar beet seeds revealed the significant effect of the interaction of all factors. Seeds with different maturity classes, from the same lot, were washed using procedures determined from the first experiment. Statistical analysis of the germination data of the washed seeds showed a significant difference in mean germination time depending on maturity class. Washing seeds of different maturity classes with 40 mL of water per gram of seed improved the germination performance of maturity classes 2 and 5, compared with 20 mL water per gram of seed. The UV absorbance of inhibitors washed from seeds differed between maturity classes. The change in seed moisture content during the washing process is another factor altered by the extent of seed development, and this variation in water uptake may reflect the pericarp structure of seed in different maturity classes. The findings in this manuscript highlight the importance of optimizing the pre-treatment procedures in accordance with the individual seed lot.

“…De Kock and coworkers (13,14) have prepared from the water-extract of sugar heet seeds an unsaturated yellow oil which acts as a powerful germination inhibitor of cress (Lepidium sativum) and other seeds and which strongly inhibits the respiration and phosphate uptake of washed sugar-beet disks. A marked inhibition of polyphenoloxidase preparations from mealworm (Tenebrio mollitor) and sugar beet was also observed.…”

“…Sugar beet seeds require sophisticated seed enhancement techniques in order to optimise their germination capacity (Habib, 2010). This is because the seeds are irregular in shape and have a hard pericarp that contains germination inhibitors (Kock et al, 1953;Salimi & Boelt, 2019). The pericarp also acts as a physical barrier to water and oxygen uptake, thereby retarding germination (Abts et al, 2013).…”

Biostimulant potential of agro-industrial side-streams - sustainable sugar beet cultivation and drought tolerance in wheat

The biostimulant potential of three agro-industrial side-streams (hydrolysed wheat gluten (HWG), potato protein (PP/PF) and the chitosan derivative KitoFlokk™ (KF/KF200) and two chitosan types (KA and KB) was compared to that of untreated controls and nutrient solution in trials with three sugar beet genotypes (Volga, Armesa, Mustang) and two spring wheat genotypes (204, 276). In general, 1-2 g/kg HWG or PP/PF applied as a soil mix enhanced sugar beet growth and physiology. Sugar beet also responded positively to increasing concentration (4-6 g per kg or L) of chitosan (KF/KF200, KA and KB), irrespective of application method (soil mix, soil drenching, foliar spray). In addition, bio-pellets containing 15% KB consistently improved growth and physiology of sugar beet. Transcriptome analysis attributed the biostimulant effects of HWG and PP/PF to upregulation of genes associated with metabolic processes (e.g. photosynthesis, protein synthesis and aromatic amino acids) compared with untreated controls. In wheat, bio-priming with 2% or 4% KF200 and foliar application of HWG, PP or 2% KF200 enhanced growth and yield components during early and late drought, with wheat genotype 276 showing better yield performance during drought than genotype 204, when primed/sprayed with biostimulants. Therefore side-streams from wheat and potato starch processing (HWG and PF) and chitosan (KA, KB and KF/KF200) from seafood processing, have biostimulant capacity, triggering metabolic processes that improve growth and bio-macromolecules in sugar beet and drought tolerance in wheat when applied as a soil mix, soil drench, foliar spray or bio-pellet.
