Objective: The cell suspension cultures of Sorbus aucuparia (SASC) was used to study the effect of abiotic elicitors-heavy metals on the SASC biomass. Method: The different concentrations of lanthanum chloride

copper nitrate

lead nitrate solution were prepared to treat the SASC

an electronic balance was used for measurement of Biomass of SASC. Result: The cell growth was stimulated by low concentration of lanthanum chloride but inhibited by high concentration of lanthanum chloride

the effect on cell growth was similar to Hormesis phenomenon

optimal stimulating concentration was 0.01 mg·L-1;low concentration of copper nitrate inhibited cell growth but high concentrations stimulated cell growth

after treated with 0.05 mg·L-1 copper nitrate the cell biomass was the lowest;substantially all concentrations of lead nitrate stimulated cell growth

the optimal stimulating concentration was 0.5 mg·L-1. Conclusion: Heavy metals affect the SASC biomass

and its role in the extent and manner may be related to elicitors' type and concentration.
