摘要

最近气候模式的变化对农民的收入产生了深远的影响,导致作物产量下降。为了对抗这些不同的环境压力源,人们开发了新的策略来提高植物的耐受性。其中,植物激素在逆境条件下对植物的应用已成为近年来研究的热点。这就需要在农业实践中使用植物激素或生物刺激剂,它们通过增强各种生化、生理和分子过程,对植物生长调节和增强恢复力具有积极影响。因此,探索这些植物激素的作用和机制对培养抗逆性具有重要意义。在这些植物激素中,褪黑激素(MT)已显示出大量证据,即使在各种非生物胁迫下也能促进种子萌发。此外,MT种子处理可以改善根形态、种子萌发、光合作用、幼苗生长、延缓叶片衰老、提高抗氧化效率、促进果实成熟,并促进细胞和组织水平的组织发生。因此,本研究旨在探讨在非生物胁迫条件下,MT种子处理对其提高种子萌发的影响,重点研究其对激素和基因表达的影响。我们的主要目的是研究MT在非生物胁迫条件下促进种子萌发、建立幼苗、促进植物发育和维持体内平衡等方面的综合效应。

Enhancing crop resilience with melatonin seed treatment in horticulture crops

Recent shifts in climate patterns have exerted a profound impact on farmers’ earnings, resulting in diminished crop yields. To counteract these diverse environmental stressors, novel strategies have been developed to enhance plants’ ability to tolerate stress. Among them, the application of phytohormones to plants under stress conditions has gained significant importance recently. This necessitates the utilization of phytohormones or biostimulators in agricultural practices, which demonstrate a positive influence on plant growth regulation and fortification of resilience through augmentation of a various biochemical, physiological, and molecular processes. Hence, exploring the effects and mechanisms of these phytohormones is of paramount importance for cultivating enhanced stress tolerance. Among these phytohormones, melatonin (MT) has shown substantial evidence of bolstering seed germination even under various abiotic stressors. Additionally, MT seed treatment has been observed to enhance root morphology, seed germination, photosynthesis, seedling growth, delay leaf senescence, boost antioxidant efficiency, facilitate fruit maturation, and promote cellular and tissue-level histogenesis. Consequently, this study aims to delve into the impacts of MT seed treatment on its augmentation of seed germination under abiotic stress conditions, focusing on the modification of hormonal and genetic expressions. Our primary objective is to investigate the comprehensive spectrum of effects triggered by MT in enhancing seed germination, establishing seedlings, promoting plant development, and maintaining homeostasis amid abiotic stress conditions.
