Accumulation and Tolerance of Zinc in Ornamental Plant Chlorophytum comosum

Abstract:

Article Preview

Chlorophytum comosum seedlings were treated with different Zinc (Zn) concentrations (CK, 200, 400, 600, 800, 1000, 1500, 2000 mg·kg-1dried growth medium) under controlled conditions. Physiological parameters and Zn content of roots and shoots were examined by pot-planting over a period of three months. The results showed that the length of roots, the fresh and the dried weight of plants were inhibited by Zn of all concentrations, while the length of aboveground parts and the volume of roots were stimulated by the lower Zn level. The Tolerance Index (TI) of C. comosum were above 50 in soil of Zn concentration less than 600mg·kg-1. In addition, results indicate that C. comosum can accumulate Pb up to 1093 mg·kg-1 and 4700 mg·kg-1 dry weight in roots and leaves respectively in Zn concentration of soil up to 2000 mg·kg-1.
