摘要
采用室内生测、室外盆栽和水培相结合的研究方法，以多种受体品种来探讨番茄 的化感作用．结果表明，番茄植物不仅具有自毒作用，番茄植株的水提液对黄瓜、萝卜、生 菜、白菜、包心菜的幼苗生长均有显著的抑制作用；番茄植株的挥发物对黄瓜的生长具有 明显的抑制作用，但对绿豆、白菜、生菜及番茄自身的幼苗生长则无明显的影响；番茄移苗 后４０ ｄ之内，其根分泌物对黄瓜生长有明显抑制作用，但对生菜作用不明显认为自毒作 用是造成番茄连作障碍的原因之一，指出番茄种植应采用轮作方式，水培或大棚种植番茄 时，应避免与黄瓜间种．
The methods of bioassay, pot experiment and water culture were adopted to explore the allelopathic effect of tomato on several plant acceptors. The results showed that tomato had an autotoxidity effect. Its aquatic extract could significantly inhibit the seedling growth of Cucumis sativas, Raphanus sativa, Lactuca sativa, Brassica perkiensis, Brassica oleracea. but its volatiles had no significant effect on that of Phaseolus aureus, Brassica perkiensis, Lactuca sativa, and tomato itself. After the tomato seedlings were transplanted for 40 days, their root exudates had a significant inhibition on the growth of Cucumis sativas, but no effect on Lactu- ca sativa. It is suggested that the autotoxidity effect of tomato is one of causes obstructing its continuous cropping, and tomato should be avoided to intercrop with Cucumtf sativas in wateror shed culture.
