摘要: 研究不同浓度肉桂酸对番茄苗期生长抑制作用以及加入碳化玉米芯缓解肉桂酸对番茄苗期生长抑制作用的效果。以肉桂酸作为番茄的连作障碍自毒物质,珍珠岩为基质进行盆栽试验,并就生物量、光合作用、根尖超微结构和MDA含量等指标的变化进行了讨论。结果表明,施用肉桂酸对幼苗的光合作用指标、生物量及叶绿素的含量具有显著的抑制作用。高浓度的肉桂酸处理使根尖的超微结构受到破坏。同时使幼苗体内MDA的含量显著增加。加入碳化玉米芯有效地缓解了肉桂酸对番茄幼苗的毒害作用。因此,施用碳化玉米芯可作为防止番茄连作障碍的措施之一。

Abstract: We examined the effects of cinnamic acid on the growth of tomato seedlings,and its alleviation of applied carbonized maize cob was shown.The tomato seedlings were transplanted in the hydroponic system with perlite as substrate,and the biomass,photosynthesis,ultrastructure of root and MDA were investigated.The results showed that cinnamic acid inhibited the biomass,photosynthesis and chlorophyll contents of tomato seedlings.Deformation of the ultrastructures of root was observed and the MDA content was increased by the treatment of high content cinnamic acid.But the inhabitations were alleviated by applied carbonized maize cob.Carbonized corn cob can be used to prevent the plants from monocropping obstacles.

Key words: Cinnamic acid, Tomato, Autotoxicity, Photosynthesis, Ultrastructure, MDA Carbonized maize cob
