Abstract: To explore the physiological and biochemical response mechanisms of plants and plant combinations and the advantages of plant combinations over single plants in phytoremediation of bisphenol A (BPA). In this study, the physiological responses to BPA of three plants, Phragmites australis, Typha Orientalis, and Triarrhena Sacchariflora, were studied. The results showed that under certain BPA concentration, some plant combinations could significantly improve the fresh weight, dry weight, photosynthetic pigment content, antioxidant enzyme activity (superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD)), antioxidant non-enzyme substance (GSH), and osmotic stress substance (Pro). The accumulation of reactive oxygen species (H2O2) and plasma membrane peroxide level (MDA) were significantly reduced. The maximum dry weight was 1.09 and 1.23 times as much as that of a single plant under the same treatment; the total chlorophyll content was 1.15 and 1.13 times as much as that of a single plant; the total chlorophyll content was 1.30 and 1.17 times as much as that of a single plant; the total chlorophyll content was 1.30 and 1.17 times as much as that of a single plant; the content of Pro was 1.09 and 1.16 times as much as that of a single plant; the content of H2O2 was 0.82 and 0.91 times as much as that of a single plant; and the content of MDA was 0.87 and 0.88 times as much as that of a single plant. This study provides a reference for revealing the physiological regulatory mechanism of the superiority of plant combinations over single plants in phytoremediation of BPA.

摘要: 为了探究植物组合内各种植物对双酚A(bisphenol A, BPA)的生理生化响应机制,及植物组合较单一植物在植物修复双酚A中的优势,本试验以湿地植物芦苇(Phragmites australis)、香蒲(Typha orientalis)和荻(Triarrhena sacchariflora)为材料,研究了3种植物及其组合对BPA的生理响应。结果表明,在一定BPA浓度下,部分植物组合可以显著提高植物鲜重、干重、光合色素含量、抗氧化酶活性[超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD)]、抗氧化非酶物质、渗透胁迫物质;显著降低活性氧积累量和质膜过氧化水平。其中,芦苇和香蒲的植物组合对BPA胁迫的耐受能力增加最为明显,干重最高达到同一处理下单一植物的1.09和1.23倍,总叶绿素含量达到1.15和1.13倍, CAT达到1.30和1.17倍,脯氨酸(Pro)含量达到1.09和1.16倍,H2O2含量达到0.82和0.91倍,丙二醛(MDA)含量达到0.87和0.88倍。本研究为揭示植物组合较单一植物在植物修复BPA中优势的生理调控机制提供了参考依据。
