Abstract/Contents: | "To investigate the effects of different cutting frequencies (no cutting, once, twice, 5 times) and different lead (Pb) concentrations (0, 500, 1 000, 1 500 mg·kg-1) on Pb accumulation in tall fescue (Festuca elata), the change in Pb form and subcellular morphological structure were analyzed and cutting tests were conducted under Pb stress in pot culture. The main results were as follows: cutting treatment increased the acidity of soil, the acid-extractable and reducible state of Pb in the soil showed an increasing trend, and the acid-extractable and reducible state content of Pb under 5 cuttings were significantly higher than those under other cutting treatments (P<0.05). As cutting frequency increased, Pb content in the stubble and root of tall fescue increased, and the aboveground Pb accumulated mainly in the stubble. Under cutting treatment, a large amount of Pb accumulated in the cell wall of the root tip of tall fescue and the dense electron layer became more obvious. The number of plastids in the mature leaf chloroplasts of stubble increased sharply and oxidative damage was aggravated. Comprehensive analysis showed that cutting treatment can improve the bioavailability of Pb in the soil, promote the absorption of Pb by the roots of tall fescue, and enhance the transport Pb to the stubble part." |
