Abstract:
With cucumber (Cucumis sativus L.) and radish (Raphanus sativus L.) as materials，the effect of different concentrations of phthalic acid on seed germination，seedling growth and root morphology of them were studied.The results showed that seed germination，seedling growth and root morphology were significantly different among different concentrations of phthalic acid treatments.Seed germination and seedling root growth of cucumber were inhibited by phthalic acid.But effects of different concentrations of phthalic acid on seed germination and root growth manifested as low concentrations promoted and high concentrations inhibited，the peak appeared at 0.05 mmol/L.In the concentration range 0.50~2.00 mmol/L，phthalic acid significant inhibited seed germination，fresh and dry matter accumulation and root growth of cucumber seedlings.
