Currently, agriculture is facing the threat of climate change. Adaptation of plants to unfavorable growth conditions is undoubtedly a great challenge for scientists. A promising solution to this problem is priming, for which chemicals, microorganisms and phytohormones can be used. The use of priming not only affects the adaptation of plants to unfavorable environmental conditions caused by water deficiency, low temperatures, heat and soil pollution, but can also improve the quantity and quality of biomass. In this review, we focus on the role of plant phytohormones in inducing priming in crop plants. We took a closer look at hormones such as abscisic acid, salicylic acid, jasmonic acid and gibberellins. We focused not only on their physiological and morphological effects, but also on what changes at the molecular level are induced by priming with phytohormones. An interesting aspect of priming is the epigenetic changes induced by phytohormones, which influence better adaptation to unfavorable conditions, which is why we addressed this topic in this review.
目前，农业正面临气候变化的威胁。使植物适应不利的生长条件无疑是科学家面临的巨大挑战。解决这一问题的一个有前景的方法是引发处理，可使用化学物质、微生物和植物激素来进行引发处理。引发处理的应用不仅影响植物对因缺水、低温、高温和土壤污染导致的不利环境条件的适应，还能提高生物量的数量和质量。在这篇综述中，我们重点关注植物激素在诱导作物引发处理中的作用。我们深入研究了脱落酸、水杨酸、茉莉酸和赤霉素等激素。我们不仅关注它们的生理和形态学效应，还关注植物激素引发处理在分子水平上诱导了哪些变化。引发处理的一个有趣方面是植物激素诱导的表观遗传变化，这些变化影响对不利条件的更好适应，这就是为什么我们在这篇综述中探讨了这个话题。
