- 摘要:
- 以凤尾竹（Bambusa multiplex cv.Fernleaf）、孝顺竹（Bambusa multiplex (Lour.) Raeuschelex J）、四季竹（Sinobambusa tootsik(Sieb.) Makino）3种观赏竹为试材，研究了自然干旱胁迫条件对3种观赏竹叶片的质膜透性(PMP)、叶片组织含水量(RWC)、丙二醛（MDA）含量以及叶绿素含量的影响。结果表明：随着干旱时间的延长，3个竹种的丙二醛含量都在不断增加，叶片质膜透性呈增加趋势，而叶片组织含水量和叶绿素含量呈下降趋势。采用模糊隶属函数法综合评价3个竹种的抗旱性，表明四季竹的抗旱性最强，其次是孝顺竹，凤尾竹的相对最弱。
- 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.
