“…Additionally, COS treatment increased TSP content in Red Norland tuber tissues at 9 d after wounding. Previously, enhanced phenolic content was observed with COS elicitor treatments in wounded potato tuber tissues (Chintha et al, 2023;Xie et al, 2023). Xie et al (2023) also observed stimulation in biosynthesis of cinnamic, caffeic, pcoumaric, and ferulic acids with COS elicitor treatment in potato tuber tissues.…”

“…Oxidative PPP provides precursors to downstream pathways such as shikimate pathway and play an important role in biosynthesis of secondary metabolites including phenolics in potato tuber tissues during WH responses (Woolfson et al, 2023). Previously, Chintha et al (2023) observed enhanced activity of G6PDH, a key rate limiting enzyme of oxidative PPP, in wounded and COS treated potato tuber tissues. Activation of G6PDH is also reported during WH of hot water treated carrot (Daucas carota L.) (Jiang et al, 2024).…”

“…Overall, COS elicitor treatment slightly enhanced the GPX activity, but it was not statistically significant in most cultivars and at any time points examined. Chintha et al (2023) reported enhanced GPX activity with COS treatment during WH of Russet Burbank tubers. Whether the impact of elicitor treatments on GPX activity is cultivar specific or not needs further evaluation.…”

“…Previously, Chintha et al (2023) observed that natural elicitors such as water-soluble chitosan oligosaccharide (COS) and cranberry pomace residue (Nutri-Cran) have positive impacts on SPP accumulation and overall WH processes in mechanically wounded tissues of potato tubers (cvs. Russet Burbank and Russet Norkotah).…”

“…and Chintha et al (2023) reported suberization rating of 3.0-4.0 after 3 and 4 d of wounding. Except for potato cultivar Red LaSoda, greater SPP rating was observed in Nutri-Cran treated tissues and it was statistically significant (p ≤ 0.05) for Dakota Rose at 3 d, Chieftain at 6 d and for Red Norland and Chieftain at 9 d, when compared to the control (MES) treatment (Figures2-4).…”

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