Abstract: In order to expand Phyllostachys violascens planting area,we try to find the reason of Ph. violascens fail to grow well even decay and death in the saline?鄄alkali land,therefore salt tolerance in Phyllostachys violascens with NaCl stress is studied,root activity and cell membrane permeability were studied in a pot culture experiment with a different concentration of NaCl(mass concentration,respectively 0,1.0 ,3.0,5.0 gL-1)treatments:(1) 12.83 gg-1h-1 treated with 0 gL-1 NaCl solution,(2) 9.4 gg-1h-1 treated with 1.0 gL-1 NaCl solution,(3) 10.80 gg-1h-1 treated with 3.0 gL-1 NaCl solution,(4) 7.22 gg-1h-1 treated with 5.0 gL-1 NaCl solution. Results showed that Treatment 1 made roots the most active,Treatment 3 was not significantly different from the control(P = 0.326),and Treatment 4 was significantly different from the control(P = 0.008). Ph. violascens showed some adaptability under NaCl stress with higher root activity in the earlier stages. However,the root system was damaged,and vigor declined over time. Cell membrane permeability of the Treatment 1 was 6.03%;there were no significant differences with Treatments 2 (6.97%)or 3 (6.93%),but Treatment 4 was greater at 8.75%. Overall,changes in cell membrane permeability were greater in the early stages of NaCl stress treatment and more stable in the later stages.[Ch,2 fig. 2 tab. 25 ref.]
