为揭示促生菌对Cd胁迫下蒌蒿光合特性的作用机理,利用具有促生功能的芽孢杆菌（Bacillus sp.,T3）,成团泛菌（Pantoea agglomerans,J2）,荧光假单胞菌（Pseudomonas fluorescens,Y5）的混合菌剂进行盆栽接种试验,研究促生菌对Cd胁迫下蒌蒿光合气体交换、光合色素、光合矿质元素和叶绿素荧光参数的影响。结果表明:接种促生菌蒌蒿净光合速率、气孔导度、蒸腾速率显著增加,胞间CO2浓度明显降低;叶绿素a,叶绿素b,总叶绿素和类胡萝卜素含量增加,叶绿素a/b值显著降低;最大光化学效率、实际光化学量子产量、相对电子传递速率、光化学淬灭系系数显著增加,非光化学淬灭系数显著降低;蒌蒿对光合矿质元素P,...

To investigate the mechanism of mixed plant growth-promoting bacteria (PGPB) on photosynthetic characteristics ofArtemisia selengensisunder cadmium stress,a pot experiment was conducted usingBacillussp.,T3,Pantoea agglomerans,J2,Pseudomonas fluorescens,Y5,while observed and analyzed the effect of PGPB on photosynthetic gas exchange,photosynthetic pigments,photosynthetic mineral elements,chlorophyll fluorescence parameters ofArtemisia selengensisunder cadmium stress. The results showed that the net photosynthetic rate (Pn),stomatal conductance (...
