Chloromycetin effects on pigment content and chlorophyll fluorescence in Phyllostachys edulis seedlings

摘要: 为了探讨抗生素对植物生长的影响,以3年生毛竹Phyllostachys edulis实生苗为材料,用Yaxin-1161型非调制式叶绿素荧光仪和JIP-test数据分析方法,研究了采用不同浓度氯霉素(CAP)对其叶片色素质量分数和叶绿素荧光特性的影响。结果表明:氯霉素处理后,毛竹幼苗叶片叶绿素a, 叶绿素b和总叶绿素质量分数显著降低(P<0.05);捕获的激子将电子传递到电子传递链中超过初级醌受体(QA)的其他电子受体的效率(ET0 /TR0)。用于电子传递的量子产额(ET0 /ABS),最大光化学效率(P0)和吸收光能为基础的性能指数(PIABS)均显著下降(P<0.05),表明氯霉素具有抑制毛竹幼苗光合性能的作用。图1表3参29Abstract: To determine the effects of antibiotics on plant growth, three-year-old Phyllostachys edulis seedlings were used as experimental materials. Then pigment content and chlorophyll fluorescence with different concentrations of chloromycetin (CAP) were determined using a non-modulated chlorophyll fluorometer (Yaxin-1161) and the JIP-test data analysis method. Results showed that chlorophyll a, chlorophyll b, and total chlorophyll content of the leaves significantly decreased (P<0.05) with the CAP treatment. A significant decrease (P<0.05) was found with the probability that a trapped exciton moved an electron into the electron transport chain beyond Quinone A (QA)(ET0 /TR0), with quantum yield for electron transport (ET0 /ABS), with maximum quantum yield for primary photochemistry (P0), and with performance index on absorption basis (PIABS). This suggested that CAP suppressed leaf photosynthetic characteristics. [Ch, 1 fig. 3 tab. 29 ref.]
