Platycrater arguta is a rare and endangered deciduous shrub originating from the Tertiary Period. Understanding its drought tolerance crucial for conservation efforts enhancing resilience to environmental stress. This study aimed assess effects of varying levels stress on phenotype physiological-biochemical characteristics P. arguta. The subjected different using 10%, 20%, 30% polyethylene glycol-6000 (PEG-6000) over 10-day period. Additionally, exogenous melatonin application at various concentrations (including 100 µM) were examined determine potential in alleviating drought-induced damage. Key parameters measured included leaf relative water content, net photosynthetic rate (Pn), antioxidant enzyme activity, soluble sugar content. Drought significantly inhibited growth As PEG-6000 concentration increased, content decreased, while wilting severity, membrane damage, increased. A caused irreversible leading plant death. Exogenous µM alleviated this damage by increasing efficiency, boosting accumulating osmotic regulators, reducing desiccation. demonstrated that sensitive severe conditions, with causing However, improved plant's upregulating expression ABI1 downregulating genes such as AUX1A-2, IAA2-2, HP2-1. finding highlights protective agent against stress, providing valuable insights enhancement arguta's challenges.

Abstract Melatonin was found in plants the late 1990s, but its function, signaling, and interaction with other phytohormones still unclear. research has increased substantially recent years, including reports on impact of this putative plant hormone under biotic abiotic stress situations. Temperature extremes, salt, drought, hypoxia or anoxia, nutrient deficiency, herbicides, UV radiation stress, heavy metal toxicity are all important obstacles to horticulture crop production worldwide. To deal these environmental challenges, have evolved complex signaling networks. Phytohormones essential for controlling growth, development, responses. Melatonin, a pleiotropic chemical present variety species, recently emerged as powerful regulator tolerance. The purpose review is investigate interplay between melatonin control responses horticultural crops. We explore interactions several various stresses.

Ornamental crops particularly cut flowers are considered sensitive to heavy metals (HMs) induced oxidative stress condition. Melatonin (MLT) is a versatile phytohormone with the ability mitigate abiotic stresses in plants. Similarly, signaling molecules such as hydrogen sulfide (H2S) have emerged potential options for resolving HMs related problems The mechanisms underlying combined application of MLT and H2S not yet explored. Therefore, we evaluated individual applications (100 μM) form sodium hydrosulfide (NaHS), donor H2S, (1.5 mM) alleviate cadmium (Cd) (50 mg L−1) stock (Matthiola incana L.) plants by measuring various morpho-physiological biochemical characteristics. results depicted that Cd-stress inhibited growth, photosynthesis Cd-associated excessive ROS accumulation. Combined efficiently recovered all these attributes. Furthermore, Cd stress-induced markers including electrolyte leakage, malondialdehyde, peroxide partially reversed Cd-stressed application. This might be attributed or antioxidant plant defense activities, which effectively reduce severity indicators. Overall, supplementation, favorably regulated tolerance stock; yet, use had greater effect on than independent
