Euphorbia jolkinii dominates the subalpine meadows in Shangri-La (Southwest China) owing to its potent allelopathic effects. However, effects underlying allelopathy require further characterization at physiological and molecular levels. In this study, physiological, biochemical, metabolic mechanisms E. were investigated using Arundinella hookeri as a receptor plant. The treatment of A. seedlings with aqueous extract (EJAE) disrupted their growth by inhibiting photosynthesis, disrupting oxidation systems, increasing soluble sugar accumulation chlorophyll synthesis. Collectively, causes severe impairment accompanied abnormal photosynthesis reduced biomass accumulation. Moreover, EJAE suppressed gibberellin, indoleacetic acid, zeatin, salicylic jasmonic acid levels while promoting abscisic Further metabolomic analyses identified numerous differentially abundant metabolites primarily enriched α-linolenic, phenylpropanoid, flavonoid biosynthesis pathways EJAE-treated seedlings. This study demonstrated that exhibits comprehensive on plants, including significant disruption endogenous hormone synthesis, inhibition an membrane changes crucial processes associated biosynthesis. Thus, our provides solid theoretical foundation for understanding regulatory allelopathy.
