In this research, the effects of Zn application on plant growth and Zn distribution were examined in two cult vats of aerobic flee under pot soil culture condition with six zinc supplied level. Both Zn deficiency and Zn toxicity affected plant growth, and reached the highest value at 5.0 mg/kg soil for both varieties. Excessive Zn application rates led to a dry matter decrease of 24.6% in Baxi Ludao. With increasing soil Zn supplied level, plants continued to take up Zn even beyond toxicity level, and the extra zinc was found to mainly store in sheath. Among .all individual plant organ, leaf zinc mass fraction was lowest, and keep relatively stable with zinc applied increased, instead of sharply rising like root and sheath.
