以生菜和大白菜两种蔬菜作物为受体,通过测定番茄植株水浸提液对两种蔬菜作物幼苗生长的影响,对番茄化感物质的作用进行了研究.结果表明：①低浓度(0.02 g/ml)的番茄水浸提液抑制大白菜幼苗的根长和根重；而促进生菜的根长和根重②高浓度(0.08 g/ml)的番茄水浸提液对生菜和大白菜幼苗根长、根重和苗长均表现为抑制作用.随着浓度的加大,抑制作用增强；③0.04 g/ml的番茄水浸提液对生菜幼苗苗长和大白菜的根重、根长/苗长有明显的促进作用,而对大白菜幼苗苗长、根长有抑制作用；榆番茄水浸提液对生菜幼苗根长/苗长比均表现为抑制作用、而对白菜的却表现为促进作用.图5,表1,参11.

The study of allelopathy on tomato plants was made through measuring seedling growth of lettuce and celegy cabbage which were watered with the aqueous extract of tomato plants. The results lead to the following conclusions:① Tomato plants aqueous extract with lower concentration(0. 02 g/ml) re-strained length of seedling root and weight of celegy cabbage,while it prompted those of lettuce.②Toma-to plants aqueous extract with higher concentration ( 0 . 08 g/ml ) inhibited significantly both lettuce's length of seedling root as well as the weight of root and those of celegy cabbage;and the effects could be enhanced with the increase of the concentration.③Tomato plants aqueous extract in this concentration of 0. 04 g/ml,on one hand,which advanced seedling length of lettuces and root weight,root length and seed-ling length of celegy cabbages;on the other hand,which inhibited seedling length and root length of cele-gy cabbage.Tomato plant aqueous extract inhibited the ratio of seedling( root length)/( shoot length) of lettuce,while this turned to be helpful for Chinese cabbage. 5figs. ,1tab. ,11refs.
