分别采用浸种和灌根的方法，研究了肉桂酸对番茄种子萌发、幼苗生长和生理特性的影响。结果表明，不同浓度的肉桂酸溶液都不同程度抑制番茄种子发芽和幼苗生长，低浓度抑制作用弱，高浓度抑制作用强，其中4.0mmol·L-1浓度处理对番茄的化感效应尤为显著。肉桂酸对番茄种子发芽的影响效应大于对幼苗生长的影响，同时肉桂酸还对番茄幼苗的生理活动产生了一定的负面影响，尤其是4.0mmol·L-1浓度处理显著增加了叶片中可溶性糖含量，降低了番茄幼苗的根系活力。

The effect of cinnamic acid on tomato (Lycopersicon esculentum Mill.)seed germination, seedling growth and physiological characteristics was studied by soaking seed and root-irrigation methods. The results showed that different cinnamic acid concentrations inhibited the tomato seed germination and seedling growth in different degrees. The inhibition effect of low cinnamic acid concentration was weak,while its impacting effect was strong,especially with 4.0 mmol·L-1 concentration treatment. The allelopathic effect of cinnamic acid on tomato germination was obvious larger than on seedling growth. At the same time,cinnamic acid had negative impact on physiological activities of tomato seedlings,especially the 4.0 mmol·L-1 concentration treatment increased significantly the soluble sugar content in tomato leaf blades,and reduced the root activity of tomato seedlings.
