Research Project: Understanding Pressure Bruise Susceptibility of Russet Potato Cultivars Using X-ray Ct and Cell Wall Analyses

Location: Small Grain and Food Crops Quality Research

Project Number: 3060-21430-009-017-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Mar 31, 2023
End Date: Mar 30, 2025

Objective:
Investigate pressure bruise susceptibility of Russet potato cultivars, and tuber’s tissue organization and the cell wall composition using state-of-the art methods to have a better understanding of the effects of long-term storage on potato tubers.

Approach:
Experiments will be conducted in a multi-institutional research setting, and the cooperator will carry out the following: Tubers of five russet potato cultivars will be submitted to the standard wound healing process after harvest. A set of tubers will be used for X-ray computed microtomography (CT) scanning to determine the cellular composition. Based on these results, tubers of two contrasting potato cultivars will be further examined with or without storage pile pressure during long-term cold storage. Samples will be collected monthly and pressure bruise development will be evaluated by integrating X-ray CT and other established methodologies. Impact of pressure bruise on the cell wall yield and composition and tuber storage quality attributes will be determined.
