Postharvest losses are a key stumbling block to long-term postharvest storage of potato tubers. Due to the high costs and lack of infrastructure associated with cold storage, this storage method is often not the most viable option. Hence, sprout suppressants are an appealing option. In most developing countries, potato tubers in postharvest storage are accompanied by a rapid decline in the potato tuber quality due to the physiological process of sprouting. It results in weight changes, increased respiration, and decreased nutritional quality. Therefore, proper management of sprouting is critical in potato storage. To avoid tuber sprouting, increased storage and transportation of potatoes demands either the retention of their dormant state or the application of sprout growth suppressants. This review evaluates the current understanding of the efficacy of different sprout suppressants on potato storability and the extension of potato shelf-life. We also consider the implications of varied study parameters, i.e., cultivar, temperature, and method of application, on the outcomes of sprout suppressant efficacies and how these limit the integration of efficient sprout suppression protocols.
收获后损失是马铃薯块茎长期收获后储存的关键绊脚石。由于与冷藏相关的高成本和基础设施的缺乏，这种储存方法往往不是最可行的选择。因此，发芽抑制剂是一个有吸引力的选择。在大多数发展中国家，收获后储存的马铃薯块茎由于发芽的生理过程而导致马铃薯块茎质量迅速下降。这会导致重量变化、呼吸增加和营养质量下降。因此，在马铃薯储存中正确管理发芽至关重要。为了避免块茎发芽，增加马铃薯的储存和运输需要保持其休眠状态或应用发芽生长抑制剂。本综述评估了目前对不同发芽抑制剂对马铃薯耐储存性和延长马铃薯货架期功效的理解。我们还考虑了不同研究参数，即品种、温度和施用方法，对发芽抑制剂功效结果的影响，以及这些参数如何限制高效发芽抑制方案的整合。
