摘要
以黄瓜、萝卜为试材,研究了不同浓度邻苯二甲酸对蔬菜种子萌发、幼苗生长及根系形态的影响。结果表明:不同浓度邻苯二甲酸对黄瓜、萝卜种子萌发及幼苗生长发育的影响存在较大差异。邻苯二甲酸不利于黄瓜种子萌发及幼苗根系生长发育;而对萝卜种子萌发及幼苗根系生长的影响表现为低浓度促进、高浓度抑制,峰值浓度为0.05mmol/L,当浓度范围在0.50～2.00mmol/L时,邻苯二甲酸显著抑制了种子萌发、幼苗干鲜物质积累及根系的生长发育。
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.
