Potato tubers are susceptible to wounding during post-harvest processes, leading quality decline, perishability and large economic losses. In this study, the potato cultivar, ‘Longshu No.7′, was foliar-sprayed with 3% chitosan (w/v) three times pre-harvest period after flowering evaluate effect of foliar spraying on suberization processing in wounds harvested tubers. Our results demonstrated that sprayed significantly reduced wound-induced fresh weight loss dry rot disease index by 37.34% 41.60% day 28 wounding, respectively. Foliar accelerated deposition suberin polyphenolic lignin at wound sites formation thicker cell layers. This occurred increased localized activities key enzymes pathways, including phenylalanine ammonia lyase, 4-coumaryl-coenzyme A ligase, cinnamyl alcohol dehydrogenase peroxidase (33.90–64.32%), as well contents cinnamic acid, sinapic flavonoids, lignins total phenolics (19.70–23.46%) wounded 7 wounding. indicated application could mitigate product damages.

Abstract Background Silicon and aluminium oxides make the bulk of agricultural soils. Plants absorb dissolved silicon as silicic acid into their bodies through roots. The moves with transpiration to target tissues in plant body, where it polymerizes biogenic silica. Mostly, mineral forms on a matrix cell wall polymers create composite material. Historically, silica deposition (silicification) was supposed occur once water evaporated from surface, leaving behind an increased concentration within tissues. However, recent publications indicate that certain proteins initiate control extent silicification. Scope Here we review scaffold formation silica, propose paradigm shift spontaneous polymerization dedicated active metabolic processes both location mineralization. Conclusion Protein activity concentrates beyond its saturation level. Polymeric structures at stabilize supersaturated allow flow stream, or bind initial condensation. Silica nucleation further are enabled polymeric scaffold, which is embedded mineral. Deposition terminated free consumed chemical moieties for binding saturated.

Therefore, finding effective strategies mitigate wound-related losses is very important from industry perspectives. Formation of protective barrier through accumulation suberin polyphenolics (SPP) a natural initial response tissues wounding. Materials methods In this study, efficacy two elicitors, such as chitosan oligosaccharide (COS 0.125 g L -1 ) cranberry pomace residue (Nutri-Cran was investigated using mechanically wounded tissue model by histological determination SPP formation in five agronomically relevant red-skin cultivars (Chieftain, Dakota Rose, Ruby, Red LaSoda, Norland). Furthermore, the potential role stress metabolic regulation involving phenolic metabolites, proline, antioxidant enzymes WH processes were also 0-9 days after Results discussion Exogenous treatments both COS Nutri-Cran resulted into enhanced surface, but impact more rapid with treatment select cultivars. Greater contents total soluble phenolic, ferulic acid, chlorogenic activity, superoxide dismutase activity observed elicitor treated at different time points reduced succinate dehydrogenase Norland Ruby 3 d, indicating suppression respiration rate. Collectively, these results suggest that can be potentially utilized an tubers for minimizing losses.
