| Summary: | The effects of wound healing on crop stand and productivity were examined on the potato (<i>Solanum tuberosum</i> L.) cultivars Alturas (Alt), Russet Burbank (RB), and Clearwater Russet (CW). Tuber yields increased linearly with an advancing wound healing period irrespective of the cultivar (R<sup>2</sup> = 0.91). In contrast to unhealed controls, RB and CW wound-healed for 8 days produced a 6% and 8% greater yield, respectively, while a shorter wound healing period of 2 days increased Alt yield by 7%. Increases in tuber yield, a consequence of enhanced specific tuber weight across wound healing periods, contributed towards increased relative crop value in Alt (13%), RB (22%), and CW (19%). In further lab evaluations, Alt exhibited increased desiccation resistance and was associated with an earlier induction (24 h post-wounding) of feruloyl transferase (FHT) compared to CW and RB. Since FHT facilitates suberin and wax development, delayed FHT induction likely promoted fresh-weight loss in CW and RB compared to Alt. Enzymatic evaluations to assess the production of reactive oxygen species to protect fresh-cut seed found that RB had the highest activities of superoxide dismutase and peroxidase. This study demonstrates the broad benefits of planting wound-healed seed while highlighting opportunities to improve best practices and genetic improvement for wound healing response. |
