Abstract:: Taking tomato variety of ‘Qinyou Fenba 101F1’ as test material,the experiment was carried out by ensuring that the growth media was thoroughly watered with varied concentrations of mepiquat chloride(30 mg/kg，50 mg/kg，70 mg/kg，90 mg/kg and 110 mg/kg) before sowing.The results showed that the growth rate of tomato could be controlled effectively by the effect of mepiquat chloride on tomato seedling,with higher concentrations leading to more obvious effect.The concentration of 50 mg/kg could have a major effect on the plant height，stem diameter，hypocotyl length，and chlorophyll content of tomato seedlings and thus made them stronger.Besides，the concentration of 70 mg/kg could also contribute to strong seedlings.To prevent spindly growth and cultivating strong seedlings of tomato,it was recommended that concentration of mepiquat chloride be applied at 50-70 mg/kg.
