Coconut holds significant importance as a fruit and oilseed crop in tropical subtropical regions. However, low-temperature (LT) stress has caused substantial reductions yield economics impedes coconut production, therefore constraining its widespread cultivation utilization. The appropriate application of potassium (K) the potential to enhance cold tolerance crops mitigate damage, but regulatory mechanisms by which K improves adaptability remain poorly understood. Transcriptome metabolomic analyses were performed on seedlings treated with LT (5 °C) room temperature (25 under various conditions: K0 (0.1 mM KCL), KL (2 KM (4 KH (8 KCL). Correlation analysis physiological indicators was also conducted. findings indicated that absorption, nutrient or osmotic regulation, accumulation substances, photosynthesis, hormone metabolism, reactive oxygen species (ROS) clearance pathways played crucial roles adaptation stress. disrupted homeostasis hormones, antioxidant enzyme activity, chlorophyll, K, regulation nutrients osmolytes. This leads downregulation genes metabolites related transporters, transcription factors, metabolism Applying helped maintain osmolytes, promoted removal ROS, reduced malondialdehyde, consequently diminishing damage seedlings. Furthermore, comprehensive metabolomics transcriptomics highlighted carbohydrate biosynthesis other secondary metabolites, amino acid lipid ABC transporters K’s role improving seedlings’ study identified pivotal biological pathways, genes, implicated acclimate
