摘要

处理土豆可能会造成瘀伤,导致质量缺陷,从而降低零售商、加工商和消费者的可接受性。了解品种特有的瘀伤易感性有助于制定适当的瘀伤管理计划。进行了一项为期两年的试验,以检验六个商业种植的赤褐色品种受撞击高度影响的瘀伤易感性。Russet Burbank、Ranger Russet、Clearwater Russet、Dakota Russet、Teton Russet和Umatilla Russet使用一种装置进行冲击,该装置将100克钢重从8、18或30厘米的高度掉落,以对静止块茎的芽端和茎端产生均匀的冲击。对黑斑瘀伤的发生率、严重程度和深度以及粉碎性瘀伤的发病率进行了评估。冲击高度和块茎末端对各品种的黑斑和碎伤有显著影响。随着撞击高度的增加,黑斑瘀伤的发生率、严重程度、深度和粉碎性瘀伤发生率都增加。在8cm的冲击高度下,不同品种或块茎末端的粉碎损伤没有显著差异,但在18cm和30cm的冲击高度上差异明显。总体而言,与所有品种的茎端相比,芽端的黑斑瘀伤发生率、严重程度和深度都较低,尽管芽端之间的反应差异取决于品种。与其他品种相比,清水罗素和达科他罗素的黑斑瘀伤发生率最高。在六个品种中,Teton Russet的黑斑挫伤发生率、严重程度和深度最低,但粉碎性挫伤发生率最高。这项研究深入了解了包括一个以上撞击高度的重要性,以制定强有力的瘀伤易感性研究方案,并为行业制定特定品种的瘀伤管理建议。

Susceptibility of Potato Cultivars to Blackspot and Shatter Bruise at Three Impact Heights

Susceptibility of Potato Cultivars to Blackspot and Shatter Bruise at Three Impact Heights

Handling potatoes can create opportunities to develop bruise resulting in quality defects that reduce the acceptability for purchase among retailers, processors, and consumers. Understanding cultivar specific bruise susceptibility can aid in developing appropriate bruise management programs. A two-year trial was conducted to examine bruise susceptibility in six commercially grown russet cultivars as affected by impact height. Russet Burbank, Ranger Russet, Clearwater Russet, Dakota Russet, Teton Russet, and Umatilla Russet were impacted using a device that dropped a 100 g steel weight from 8, 18, or 30 cm height to deliver a uniform impact on both the bud and stem end of a stationary tuber. Blackspot bruise incidence, severity and depth, and shatter bruise incidence were evaluated. Blackspot and shatter bruise were significantly influenced by impact height and tuber end in all cultivars. As impact height increased, blackspot bruise incidence, severity, depth, and shatter bruise incidence increased. There were no significant differences among cultivars or tuber ends in shatter bruise at the 8 cm impact height, but differences became evident at 18 and 30 cm impact heights. Overall, the bud end had lower blackspot bruise incidence, severity, and depth compared to the stem end for all cultivars, although the response difference between ends was dependent on cultivar. Clearwater Russet and Dakota Russet had the highest blackspot bruise incidence compared to other cultivars. Teton Russet had the lowest blackspot bruise incidence, severity rating, and depth among the six cultivars but had the highest shatter bruise incidence. This study provided insight on the importance of including more than one impact height to develop robust bruise susceptibility research protocols as well as develop cultivar-specific bruise management recommendations for the industry.
