摘要

The effect and the action mechanism of lanthanum on GF_(43) plantlet in vitro were studied. The results of experiments show that root growth rate and dry weight of GF_(43) by LaCl_3 treatments increase . The activities of antioxidant enzymes in root system such as superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) apparently enhance. Moreover centre dot O_2~- and malond ialdehyde (MDA) contents and cell membrane permeability of GF_(43) are decreased by LaCl_3. The relatively stable membrane structure of cell could also be maintained and the root ageing of GF_(43) plantlet in vitro delays.
