Abstract

To understand drought resistance capacity of Chimonobambusa marmorea f. variegata and how it occurs，the dynamics of C. marmorea f. variegata and its levels of superoxide dismutase （SOD），catalase （CAT），malondialdehyde （MDA），and chlorophyll were determined with leaves experiencing conditions of natural drought and rewetting. Results indicated that as drought stress continued（0 － 30 d），chlorophyll content significantly（P＜0.01） decreased from 4.470 to 1.676 mgg－1 and after 30 d treatment remained stable. CAT and SOD increased significantly（P＜0.01） as drought stress increased（0 － 30 d），and after 30 d treatment maintained high levels. MDA levels were highest when 40 d treatment. After rewetting for 5 d，chlorophyll and CAT remained unchanged，whereas SOD and MDA decreased significantly（P＜0.01） when 5 d rewetting. This indicated that a self-repair mechanism in the leaf cell membrane of bamboo was strong，and therefore，Chimonobambusa marmorea f. variegata was a drought-tolerant plant.［Ch，1 fig. 2 tab. 14 ref.］
