| description | This work presents the results of experimental tests to evaluate the effects of prolonged contamination by Cr on <i>Moso Bamboo</i> (<i>MB</i>) (<i>Phyllostachys pubescens</i>) and the adaptability of the <i>MB</i> to the Mediterranean climate. A preliminary test on the <i>MB</i> was developed in the laboratory, simulating irrigation under Mediterranean conditions (600 mm per year) and tropical conditions (1800 mm per year), to evaluate the rate of growth and the <i>MB</i>’s capability for Cr phytoextraction from contaminated soil. The tolerance of <i>MB</i> to Cr was also performed showing a good response of the plant to 100 mg Cr/L solution, utilized for irrigation of the pots. The results show that the rate of <i>MB</i>’s removal of Cr from soil ranged from 49.2% to 61.7% as a function of the soil degree of contamination, which varied from approx. 100 mg/kg to 300 mg/kg. The distribution of Cr in the various sections of the bamboo revealed that the greater percentage was present in rhizomes: 42%, equal to 114 mg Cr for 600 mm per year, and 50%, equal to 412 mg Cr for 1800 mm per year. A noteworthy diffusion of the metal towards the outermost parts of the plant was shown. The values of Cr retained in the stems and leaves of <i>MB</i> tissues were quite high and varied from 1100 mg/kg to 1700 mg/kg dry weight. |
