The phytoextraction ability and responses of sunn hemp, sunflower, and marigold plants were investigated toward carbaryl insecticide at 10 mg L and its degradative product (1-naphthol). All test plants exhibited significant carbaryl removal capability (65-93%) with different mechanisms. Marigold had the highest translocation factor, with carbaryl taken up, translocated and accumulated in the shoots, where it was biotransformed into 1-naphthol. Consequently, marigold had the least observable toxicity symptoms caused by carbaryl and the highest bioconcentration factor (1848), indicating its hyperaccumulating capability. Sunflower responded to carbaryl exposure differently, with the highest carbaryl accumulation (8.7 mg kg) in roots within 4 days of cultivation, leading to a partial toxicity effect. Sunn hemp exhibited severe toxicity, having the highest carbaryl accumulation (91.7 mg kg) that was biotransformed to 1-naphthol in the sunn hemp shoots. In addition, the different models were discussed on plant hormone formation in response to carbaryl exposure.
研究了黄秋葵、向日葵和万寿菊植物对 10mg/L 克百威杀虫剂及其降解产物(1-萘酚)的植物萃取能力和反应。所有测试植物都表现出显著的克百威去除能力(65-93%),具有不同的机制。万寿菊具有最高的转运因子,将克百威吸收、转运和积累在地上部分,并在那里将其生物转化为 1-萘酚。因此,万寿菊表现出的克百威毒性症状最少,生物浓缩因子最高(1848),表明其具有超积累能力。向日葵对克百威暴露的反应不同,在培养的第 4 天,根中积累的克百威最高(8.7mg/kg),导致部分毒性效应。黄秋葵表现出严重的毒性,在黄秋葵地上部分将最高量的克百威(91.7mg/kg)生物转化为 1-萘酚。此外,还讨论了不同模型对植物激素形成的响应。
