Bisphenol A (BPA) is a widely used chemical, that can potentially be toxic to plants. In this study we examined the toxicity of 5-50 mg/l of BPA on Arabidopsis thaliana. Additionally, the effects of 0.5-5 mg/l of BPA were examined after four weeks of development. BPA had no effect on the germination rate and the chlorophyll a/b ratio. The chlorophyll a and carotenoid content was significantly elevated in seedlings treated with 5 mg/l of BPA. In 4-week-old plants there was no change in the chlorophyll and carotenoid content and photosynthetic parameters (F/F, F/F and PI) were unaffected, which suggests no photoinhibition. No oxidative stress symptoms were observed. BPA significantly decreased leaf protein content. A low concentration of BPA seems to have no significant effect on A. thaliana flowering, but further investigation is needed. The results obtained indicate that a low concentration of BPA has no negative effect on the growth and development of A. thaliana.
双酚A（BPA）是一种广泛使用的化学物质，可能对植物有毒。在本研究中，我们检测了5-50毫克/升双酚A对拟南芥的毒性。此外，在发育四周后检测了0.5-5毫克/升双酚A的影响。双酚A对发芽率和叶绿素a/b比值没有影响。用5毫克/升双酚A处理的幼苗中叶绿素a和类胡萝卜素含量显著升高。在4周龄的植物中，叶绿素和类胡萝卜素含量没有变化，光合参数（F/F、F/F和PI）未受影响，这表明没有光抑制。未观察到氧化应激症状。双酚A显著降低叶片蛋白质含量。低浓度的双酚A似乎对拟南芥开花没有显著影响，但需要进一步研究。所得结果表明，低浓度的双酚A对拟南芥的生长发育没有负面影响。
