摘要: 通过基质栽培研究不同浓度的苯丙烯酸对黄瓜幼苗光合作用和超微结构的影响。结果表明,
苯丙烯酸浓度在80 µmol·L 时显著地降低了黄瓜幼苗的叶面积、叶绿素a含量、光合速率、蒸腾速率、根系活力和气孔张开数(P<0.05);叶绿体和线粒体等超微结构也受到破坏,而浓度在150 µmol·L 时显著减少了全株干质量和气孔总数,细胞器出现解体现象。

The innuence of cinnamic acid at diferent concentrations(O,80,150 µmol·L )on leaf gas exchange and cell uhrastructure of cucumber seedlings was investigated in substrate culture. Resulted showed that the einnamie acid at 80 µmol·L significantly reduced the leaf-area,the content of chlorophyll
a,the photosynthesis rate,the respiratory rate,the activity of root and the opening number of stomata,aceompanied by a deformation of the ultrastructures of chloroplast,mitoehondfion.More significa t effects were
observed at a 150 µmol·L cinnamie acid treatment.All these showed that cinnamic acid significantly influenced the photosynthesis by reducing the activity of root,function of the chloroplast and mitoehondrion,stomata

Key words: Cucumber, Cinnamic acid, Root activity, Photosynthesis, Uhrastructure
