摘要：
The effect of boric acid on the ability of herbaceous plants to absorb heavy metals has been studied. The results show that at a low content of boron in sandy loam soil (0.0007 mg/kg dry matter), boric acid at doses of 0.1-3.0 kg/ha stimulates the accumulation of certain heavy metals in the aboveground part of plants from the families Asteraceae (Taraxacum officinale Wigg.), Poaceae (Phleum pratense L.), and Fabaceae (Trifolium pratense L.). The most active accumulation is characteristic of dandelion (T. officinale) plants, which allows this species to be considered promising for phytoremediation of soils with a low boron content given that boron is applied at specified doses.
