Abstract:
Taking B.multiplex cv.Fernleaf， B.multiplex (Lour.) Raeuschelex J，S.tootsik(Sieb.) Makino as materials,the effects of contents of membrane permeability(PMP)，RWC，MDA content and chlorophyll content of three bamboo leaves were studied under natural drought stress conditions.The results showed that cell membrane permeability and the MDA contents of bamboo leaves increased，RWC and chlorophyll content decreased with the prolongation of the stress time.The method of obscure mathematics was used to evaluate their drought resistance ability comprehensively based on physiological and biochemical indexes.The results indicated that drought resistance sequence of S.tootsik (Sieb.) Makino> B.multiplex (Lour.) Raeuschelex J > B.multiplex cv.Fernleaf.
