Abstract: In this peper, the salt-stress responses in six species of bamboo were studied. Under saltstress, the root viability of all species and the malondialdehyde (MDA) content in bamboo shoots andleaves decreased and increased, respectively. Most of the species showed some adaptability to NaCltreatment, With prolonging duration of tteatment, the root viability was Partially recovered and the degree of membrane -lipid peroxidation was alleviated. The changes in root viability and MDA contentshowed to some extent difference among those species. Addition of Ca~(2+) markedly alleviated the effectsof salinity on Arundinaria var. disticha. The NaCl-induced accumulation of MDA was significantly inhibited by supplemental Ca~(2+). The exogenous calcium recovered pert of the root viabilitycauced by NaCl stress.
