This study investigated the effects of microbial species and dilution rates on seed germination and seedling growth of watermelon ( Citrullus lanatus) through biological seed treatment. Six microbial strains, including three Bacillus strains, Pseudomonas fluorescens (KACC12332), Bacillus subtilis (KACC13751), and Escherichia coli, were applied to watermelon seeds at four dilution levels (standard, 1/2, 1/4, and 1/8). Parameters assessed included germination percentage, germination speed (T<sub>50</sub>), normal seedling rate, and early seedling growth. Higher microbial concentrations generally resulted in germination delay and lower germination rates. Among the tested treatments, Bacillus 3 at the 1/2 dilution level showed the most favorable germination performance, with 100% germination, 100% normal seedling rate, and a T<sub>50</sub> of 1.7 days. It also produced the most vigorous seedlings with a root length of 7.3 cm, fresh weight of 241.3 mg, and dry weight of 18.3 mg. In contrast, high concentrations of P. fluorescens significantly inhibited both germination and seedling growth, whereas E. coli and B. subtilis treatments showed negligible physiological effects. These results suggest that the physiological interaction between microbial inoculants and watermelon seeds can vary depending on strain and concentration. Overall, Bacillus 3 at a 1/2 dilution and Bacillus 2 at a 1/4 dilution were the most effective in enhancing seed vigor and promoting early seedling development, highlighting their potential as biological seed-coating agents for watermelon cultivation.
