Abstract

Purpose. Establishing the influence of hyperthermal treatment of lettuce seeds and chemical contamination in the soil on the growth rates of seedlings. Methodology. The paper determines the level of influence of two factors on the growth characteristics of lettuce used for biotesting of soil contaminated with petroleum products. In accordance with the purpose of the study, lettuce seeds were pre-heat treated at a temperature of 60 C. Processing time - 5 minutes Pre-viously, a study was conducted to select the inhibitory and hormesis action of heat treatment (heat treatment time). After heat treatment, the envelopes with the seeds were dried. Next, lettuce seeds were sown in the plant. Originality. If we consider that heat treatment simulates the action of certain factors, or the complex action of certain factors, it means that we must take this into account and use certain sensitized objects in the practice of biotesting. Practical meaning. The effect of chemical soil contamination (aviation kerosene) on the sensitized plant object has been determined. Namely, lettuce used in the practice of biotesting of soil contaminated with petroleum products. The dependence of lettuce growth characteristics on the level of excess aviation fuel content in the soil is determined. Conclusions. As a result of the analysis of the received experimental data it is established that for the minimum of the used concentrations of pollu-tant (1 OAC for aviation kerosene) the sensitizing effect of additional influence of another factor - by nature - hyper-thermia is possible. This fact requires the improvement of the practice of determining the OAC, because in real condi-tions, the objects are exposed to a set of factors, the negative effects of which may be mutually reinforcing.
沙拉种子高温处理及土壤化学污染对芽苗菜生长指标影响的研究
目的。建立生菜种子过热处理和土壤化学污染对幼苗生长速率的影响。方法。测定了两种因素对石油产品污染土壤中生菜生长特性的影响程度。根据研究目的,将生菜种子在60℃的温度下进行预处理,处理时间- 5分钟。在此之前,对热处理的抑制和激效作用(热处理时间)进行了选择研究。热处理后,装有种子的信封被干燥。接下来,在植株中播种莴苣种子。创意。如果我们认为热处理模拟了某些因素的作用,或某些因素的复杂作用,这意味着我们必须考虑到这一点,并在生物试验的实践中使用某些致敏对象。现实意义。测定了化学土壤污染(航空煤油)对敏化植物客体的影响。即莴苣用于土壤污染的生物试验实践中的石油产品。确定了生菜生长特性对土壤中过量航空燃料含量水平的依赖性。结论。对所收到的实验数据进行分析后,可以确定,对于使用的最低污染物浓度(航空煤油为1 OAC),另一个因素(按性质而言)的附加影响的致敏效应是可能的。这一事实要求改进确定OAC的做法,因为在实际条件下,物体受到一系列因素的影响,这些因素的负面影响可能是相互加强的。
