Seed germination is a critical phase in plant growth, significantly influencing crop yield and quality. The primary objective was to determine the compound's efficacy in enhancing germination rates and vigor by monitoring key indicators such as germination percentage, speed, and seedling development. A range of concentrations was tested to identify optimal dosages and effects. Results indicated that dimethyl (1-hydroxy-1-phenylethyl) phosphonate, at specific concentrations, significantly improved germination speed and uniformity, with enhanced early growth metrics compared to untreated controls. The findings suggest that this compound may be an effective germination promoter in agricultural applications, potentially reducing germination time and improving crop establishment under diverse conditions. https://cjes.guilan.ac.ir/article_8138_4e1ec35afa55a0db8f15e4fb01ce31c5.pdf
