Abstract

The uptake experiments with pesticides were performed to clarify differences among plant species, and the influence of growth stages and conditions on the uptake and translocation ability of pesticides. There were 2-10-fold differences among plant species in the root and shoot concentrations of each pesticide, and shoot concentrations of pesticides in L. var. were relatively high. In addition, the changes in shoot concentrations with growth stage of were affected by root system development. The influence of temperature on uptake and translocation ability differed for each pesticide, while uptake and translocation ability were high for short day lengths. This indicated that plant uptake and translocation of pesticides were affected by root system development and growth conditions such as temperature and day length, not only the relationships to the chemical's properties and behavior of organic chemicals in the soil.

摘要

进行了农药吸收实验，以阐明不同植物物种之间的差异，以及生长阶段和条件对农药吸收和转运能力的影响。每种农药在根和地上部分的浓度在不同植物物种之间存在2至10倍的差异，并且L. var. 中农药的地上部分浓度相对较高。此外，地上部分浓度随生长阶段的变化受根系发育的影响。温度对每种农药吸收和转运能力的影响各不相同，而短日照条件下吸收和转运能力较高。这表明植物对农药的吸收和转运不仅受化学物质性质以及有机化学物质在土壤中行为的影响，还受根系发育和温度、日照长度等生长条件的影响。
