人类面临的挑战是，必须增加粮食生产，以养活呈指数增长的世界人口，而作物病害使产量下降到我们再也负担不起的水平。此外，水果收获后会产生大量废物。在收获后，由于疾病导致的水果腐烂可能占全球总产量的50%。目前，最有效的疾病控制手段是使用杀虫剂。然而，由于毒性，它们在收获后的使用极其有限。在过去几十年中，开发了更安全的收获后疾病控制方法。它们都已被纳入旨在实现害虫（和疾病）综合管理（IPM）以将农药使用量减少到最低限度的计划中。不幸的是，这些方法未能提供稳健的解决方案。因此，有必要制定可导致有效控制的替代战略。利用植物的免疫能力被认为是预防收获后疾病的一种可行途径。也有报道称，通过使用来自生物来源、生物控制和物理手段的更安全的化学物质，收获后诱导了抗性（IR）。在这篇综述中，我们总结了这些不同策略的成功活动，并探讨其背后的机制。我们进一步探讨引发的概念，以及它的持久性和广谱性如何有助于水果抗性。
Humanity faces the challenge of having to increase food production to feed an exponentially growing world population, while crop diseases reduce yields to levels that we can no longer afford. Besides, a significant amount of waste is produced after fruit harvest. Fruit decay due to diseases at a post-harvest level can claim up to 50% of the total production worldwide. Currently, the most effective means of disease control is the use of pesticides. However, their use post-harvest is extremely limited due to toxicity. The last few decades have witnessed the development of safer methods of disease control post-harvest. They have all been included in programs with the aim of achieving integrated pest (and disease) management (IPM) to reduce pesticide use to a minimum. Unfortunately, these approaches have failed to provide robust solutions. Therefore, it is necessary to develop alternative strategies that would result in effective control. Exploiting the immune capacity of plants has been described as a plausible route to prevent diseases post-harvest. Post-harvest-induced resistance (IR) through the use of safer chemicals from biological origin, biocontrol, and physical means has also been reported. In this review, we summarize the successful activity of these different strategies and explore the mechanisms behind. We further explore the concept of priming, and how its long-lasting and broad-spectrum nature could contribute to fruit resistance.
