It was shown that cadmium causes a slowdown of green foxtail Setaria veridis (L.) Beauv. shoots; however it had no effect on root growth or accumulation of underground and above-ground biomass. In the analysis of the effect of cadmium on the water regime and photosynthesis of plants, it was found that it had a negative effect on the stomatal-apparatus, which led to a decrease in the transpiration rate and stomatal conductance. It was noted that the water content of tissues, as well as the rate of photosynthesis in the presence of cadmium, reinained at the level of those in'control planrits. A high resistance of green foxtail to the effects of cadmium was established, which is provided with different adaptive mechanisms and anatomical and physiologicdal characteristics associated with its affiliation to the group of C4-plants.
结果表明，镉会导致绿狗尾草（Setaria veridis (L.) Beauv.）地上部分生长减缓；然而，它对根系生长或地下和地上生物量的积累没有影响。在分析镉对植物水分状况和光合作用的影响时发现，它对气孔装置有负面影响，导致蒸腾速率和气孔导度降低。值得注意的是，镉存在时组织的含水量以及光合作用速率保持在对照植物的水平。已确定绿狗尾草对镉的影响具有高度抗性，这与其属于C4植物组相关的不同适应机制以及解剖学和生理学特征有关。
