Abstract：The aim of present study was to explicit the effects of Bacillus subtilis B67 on the growth and development of cucumber seedlings.Different concentrations of Bacillus subtilis B67 were applied under hydroponic conditions and growth promotion in root (i.e.root length,root surface area,root volume,average root diameter,number of root tips and root fresh and dry weight) and shoot (i.e.stem diameter,shoot length,shot fresh and dry weights) parameters and root shoot ratio were recorded.The best treatment was the concentration of 20％ Bacillus bacteria growth of cucumber 2 times,after 21 day average diameter was 4.88 mm,plant height was 11.15 cm,root length was 21.65 cm,root shoot ratio was 0.94 and the treatment results were significant different.The results showed that the strain B67 applied at different concentration exhibit normal distribution in plant growth parameters,while the maximum growth promotion in cucumber seedlings reaches when it was applied at 20％ level two times (7 d interval),suggesting strain B67 could be integrated into commercial fertilizers.
