Abstract
This study identified the physiological characteristics of Alnus firma seedlings collected from air polluted industrial complex of Yeosu area with inoculation of nitrogen-fixing nodule. A. firma individuals resistant or sensitive to air pollution stress at the study area were selected. Seeds of the individuals were sown in a pot and inoculated with the nodules collected at the same area about 3 weeks after germination. To compare the inoculation effects, photosynthesis was measured among the A. firma seedlings under 12 inoculation combinations of seed sources and nodule sources. Photosynthetic activities of seedlings from resistant mother trees were obviously higher than those from sensitive mother trees. In general, the seedlings inoculated with nodule of sensitive trees, showed a worse physiological trend on every combination. In this study, inoculation effect was less important factor than seed sources to photosynthetic activities of A. firma. This physiological characteristic seemed to be determined by seed sources rather than nodule sources.
