Adding activated carbon into culture medium could reduce the autotoxic effects on the second-batch seedlings.

接种于生根培养基和继代生长培养基上的二茬苗具有最明显的自毒抑制现象，其次是接种于初代培养基上的二茬苗，在培养基中添加活性碳可降低二茬苗受到的抑制。

Base on these phenomena, this study investigated the different responses of roots of these two species to cinnamic acid, in respect of the metabolism of reactive oxygen species, metabolism of water in plant, nutrient ion uptake and the growth in order to clarify the mechanism of the autotoxic effect of cinnamic acid on cucumber.

基于这一有趣的现象，本研究以黄瓜及黑籽南瓜为材料，通过对比研究两者受到自毒物质肉桂酸(cinnamic acid，CA)侵害时在活性氧代谢、水分代谢、养分吸收及生长等方面的响应差异，进一步探讨CA对黄瓜生理代谢过程的影响机制，主要结果如下： 1 0.25mM CA处理3天激发了黄瓜根系质膜NADPH氧化酶活性的显著提高，增加了活性氧H_2O_2和O_2~

Allelopathic effects of vanillin and cinnamic acid, two eggplant autotoxic substances, on pepper seed germination, seedling growth and mycelium growth of Fusarium oxysporum f.sp with different concentrations were studied in laboratory and bioassay experiments by a simulative way.

运用模拟的方式，采用生物测定和室内培养的方法，研究了两种茄子自毒物质香草醛和肉桂酸各浓度对辣椒种子萌发和幼苗生长的化感效应，及其对辣椒枯萎菌菌丝生长的影响。

The results suggested that the decomposing substances after cotton stalks returned to soil have autotoxic effect. Cotton seed germination and photosynthesis physiological activities were affected by decomposed substances of cotton stalks.

表明棉花秸秆还田后分解产生的化学物质具有一定的自毒效应，对连作棉花种子萌发、抗氧化物酶活性和光合生理造成影响。

Root activity of eggplant seedling decreased with the concentration of the methanol isolatable components increasing. Autotoxic substances in the methanol isolatable fraction suppressed the absorption of NO〓, PO〓, K〓, Mg〓 and Ca〓, implying the inhibition effect of the substances on ion uptake was one of the important mechanisms in allelopathy.

茄子幼苗的根系活力随水提物中醇溶性组分浓度的增加而降低，同时植株对NO〓、PO〓、K〓、Mg〓、Ca〓等离子的吸收受阻，因此抑制离子吸收是水提物中自毒物质的重要效应之一。

Laboratory and greenhouse experiments were conducted to determine if the autotoxic effect is responsible for continuous cropping obstacle of chrysanthemum " Gaoyataizi" and the autotoxic effects of different parts from continuous cropping chrysanthemum on seed germination and seedling growth, cuttings rhizogenesis and the growth of potted-chrysanthemum "Gaoyataizi".

为此本论文旨在以连作障碍典型品种之一的'高压太子'为材料，采用室内生测及温室盆栽对菊花的自毒作用进行如下研究探讨：自毒作用是否是导致菊花连作障碍的因素之一；菊花不同部位水浸液处理对自身种子萌发、幼苗生长、扦插生根及盆栽菊花生长及其重要生理生化过程的自毒效应。

Allelopathic effect on the peppers and eggplants seed were obviously different. The pepper seeds appeared an apparent lower inhibition comparing to eggplant seeds after treating with two autotoxic substance.

香草醛和肉桂酸对辣椒和茄子种子的化感效应存在较大差异，辣椒种子受这两种自毒物质的抑制强度明显弱于茄子种子。
