%X The effects of the ectomycorrhizal fungus Pisolithus tinctorius and cadmium (Cd) on physiological properties and Cduptake by Populus alba กม glandulosa was investigated under greenhouse conditions. Cd treatment decreased the photosyntheticrate (PN) of both non-mycorrhizal (NM) plants (16.3%) and ectomycorrhizal (ECM) plants (11.5%). In addition,the reduction in total dry weight by Cd treatment was greater in ECM plants (24.3%) than that in NM plants (17.6%). Mycorrhizalinfection increased the PN and transpiration rate in both control and Cd-treated plants. Cd treatment increasedsuperoxide dismutase (SOD) activity and decreased glutathione reductase activity, and the increase of SOD activity byCd treatment was greater in NM plants (40.3%) than that in ECM plants (3.7%). Thiol content increased in both NM andECM plants treated with Cd solution, and the increase in thiol content in NM plants (43.9%) was greater than that of ECMplants (15.6%). Cd uptake in the leaves, stems, and roots of ECM plants was 69.9%, 167.2% and 72.8%, respectively, higherthan in the NM plants. However, the increase in Cd uptake ability of ECM plants resulted in a reduction in dry weight.
