Abstract	Pot experiments were carried out to examine the responses of growth, physiological properties, copper (Cu) absorption and translocation in two bamboo species, Phyllostachys auresulcata ‘Spectabilis’ and Pleioblastus chino ‘Hisauchii’ Two-year old plants with similar size were exposed to excess Cu treatments, in order to demonstrate their Cu tolerance and potential ability of phytoremediation under Cu-polluted soil as biofuel feedstock. Pots were irrigated with aqueous solutions of Cu in concentrations of 500, 1000 and 2000 mg CuSO$_{4}$·5H$_{2}$O kg$^{−1}$, against the control (tap water). Plant growth, chlorophyll contents, photosynthesis rate, malondialdehyde (MDA) content, Cu concentrations in leave, stem and root, and Cu contents in shoot per pot were measured after transplanted plants were grown under excess Cu treatments for 60 days. Two bamboo species had different responses to tolerance and allocation of supplied Cu. As Cu treatments rose, the percentage of senescent shoot and MDA content increased, and the chlorophyll content and photosynthetic capacity decreased. Such changes in Hisauchii were more obvious than in Spectabilis. However, number of emerged shoots did not differ between the two species across four Cu treatments. In the efficiency of decontamination, Hisauchii was more effective than Spectabilis, since either the Cu concentrations in leaves, stems and roots or Cu contents in shoot per pot in Cu treatments from 500 to 2000 mg kg$^{−1}$ were higher in Hisauchii than in Spectabilis It is suggested that the potential capability of absorbing Cu might cause the different response to cu stress between the two bamboo species. Both bamboo species can be considered to exhibit enough potential to develop in Cu-polluted areas of China as bioenergy resources and phytoremediation plants.
